Chapter 8: Playing the Game

Source Player Core pg. 397
At this point, you have a character and are ready to play Pathfinder! Or maybe you're the GM and you're getting ready to run your first adventure. Either way, this chapter provides the full details for the rules outlined in Chapter 1. This chapter begins by describing the general rules and conventions of how the game is played and then presents more in-depth explanations of the rules for each mode of play.

Before diving into how to play Pathfinder, it's important to understand the game's three modes of play, which determine the pace of your adventure and the specific rules you'll use at a given time. Each mode provides a different pace and presents a different level of risk to your characters. The Game Master (GM) determines which mode works best for the story and controls the transition between them. You'll likely talk about the modes less formally during your play session, simply transitioning between exploration and encounters during the adventure, before heading to a settlement to achieve something during downtime.

The most intricate of the modes is encounter mode. This is where most of the intense action takes place, and it's most often used for combat or other high-stakes situations. The GM typically switches to encounter mode by calling on the players to “roll for initiative” to determine the order in which all the actors take their turns during the encounter. Time is then divided into a series of rounds, each lasting roughly 6 seconds in the game world. Each round, player characters, other creatures, and sometimes even hazards or events take their turn in initiative order. At the start of a participant's turn, they gain the use of a number of actions (typically 3 in the case of PCs and other creatures) as well as a special action called a reaction. These actions, and what you do with them, are how you affect the world within an encounter. The full rules for playing in encounter mode start on page 435.

In exploration mode, time is more flexible and the play more free-form. Minutes, hours, or even days in the game world pass quickly in the real world, as the characters travel cross-country, explore uninhabited sections of a dungeon, recover from a battle, or roleplay during a social gathering. Often, developments during exploration lead to encounters, and the GM will switch to that mode of play until the encounter ends, before returning to exploration mode. The rules for exploration start on page 438.

The third mode is downtime. During downtime, the characters are at little risk, and the passage of time is measured in days or longer. This is when you might forge a magic sword, research a new spell, or prepare for your next adventure. The rules for downtime are on page 440. Sections covering each of the modes of play detail how the structure of those modes works during a game session. The other portions of this chapter explain rules that come up throughout the course of the game.

Making Choices

Source Player Core pg. 397
Throughout the game, the GM describes what's happening in the world and then asks the players, “So what do you do?” Exactly what you choose to do, and how the GM responds to those choices, builds a unique story experience. Every game is different, because you'll rarely, if ever, make the same decisions as another group of players. This is true for the GM as well—two GMs running the exact same adventure will put different emphasis and flourishes on the way they present each scenario and encounter.

Often, your choices have no immediate risk or consequences. If you're traveling along a forest path and come across a fork in the trail, the GM will ask, “Which way do you go?” You might choose to take the right fork or the left. You could also choose to leave the trail, or just go back to town. Once your choice is made, the GM tells you what happens next. Down the line, that choice may impact what you encounter later in the game, but in many cases nothing dangerous happens immediately.

But sometimes what happens as a result of your choices is less than certain. In those cases, you'll attempt a check, as described starting on page 400.

The Pathfinder Baseline

Source Player Core pg. 397
Your group will likely talk about what types of content you want in your game before your campaign begins. The following is a set of basic assumptions that works for many groups. The GM can find more guidance in GM Core.
  • Bloodshed, injuries, and even dismemberment might be described. However, excessive descriptions of gore and cruelty should be avoided.
  • Romantic and sexual relationships can happen in the game, but players should avoid being overly suggestive. Sex happens “off-screen.” One player character attempting to initiate a relationship with another should generally be avoided.
  • Avoid excessively gross or scatological descriptions.
Player characters shouldn't perform the following acts:
  • Torture
  • Rape, nonconsensual sexual contact, or sexual threats
  • Harm to children, including sexual abuse
  • Owning slaves or profiting from slavery
  • Reprehensible uses of mind-control magic

Villains might engage in such acts “off-screen,” but many groups choose to not have villains engage in these activities.

Rules Overview

Source Player Core pg. 398
This section summarizes the rules found elsewhere in this chapter.

Modes of Play

Source Player Core pg. 398
This game presents three main methods of structuring play.

Encounter mode (page 435) is highly structured and is most often used for combat or stressful situations. Everyone in an encounter rolls initiative (page 435) to determine the order they act, with highest results going first. A participant takes their turn when their initiative comes up (page 435). You can Delay to change when you take your turn (416).

Exploration mode (page 438) takes place over minutes or hours. You use your travel Speed if you're moving, and you engage in exploration activities like Avoiding Notice, Detecting Magic, Scouting, or Searching. You can rest for the night while exploring to recover HP and abilities, and make daily preparations at the start of each day (page 439).

Downtime mode (page 440) takes place over days. You might make money, train, or recover, among other things.

Actions

Source Player Core pg. 398
During an encounter, you get 3 actions and 1 reaction per turn (page 435). Icons indicate whether your abilities take a single action [one-action] , 2 actions [two-actions] , 3 actions [three-actions] , a reaction [reaction] , or a free action [free-action] . Reactions have triggers (page 414), allowing you to take them whenever they come up. The Ready basic action (page 417) lets you prepare to use a single action as a reaction. Free actions can have triggers like reactions; a free action with no trigger can be used like a single action, but don't cost any of your actions for the turn.

The most important actions to learn are the basic actions (page 416). Specialty basic actions come up less frequently, and you typically won't look them up until you need them. Speaking (page 419) normally doesn't take an action.

Related: Activities (page 414), disrupting actions (415)

Rolling Checks

Source Player Core pg. 398
An action that can potentially fail requires rolling a check (page 400). Roll a d20 (20-sided die) and identify the modifiers, bonuses, and penalties that apply. Then, calculate the result, compare it to the DC (your target number), and determine the degree of success and the effect.

Most checks are modified by your attribute modifier (Strength, Dexterity, Constitution, Intelligence, Wisdom, or Charisma) and your proficiency modifier (untrained, trained, expert, master, or legendary) for the statistic. You might get a circumstance, status, or item bonus or penalty as well.

The degrees of success (page 401) are critical success, success, failure, and critical failure. You get a success if you meet or exceed the DC, or a critical success if you exceed the DC by 10 or more. If your result is lower than the DC, you get a failure, or a critical failure if you failed by 10 or more.

Effects

Source Player Core pg. 398
An effect is the rules term for anything that occurs in the game world. Effects might have limited range (page 426), and you may need to designate targets (page 426) or create areas (page 426) for your effects. Areas include bursts from a single point, cones blasting out from you, emanations surrounding you or another creature, or straight lines.

Effects that last for a period of time list a duration (page 426). These can last a set increment of time, or can end if certain requirements are met. Many effects apply conditions (page 442), which measure advantages or impediments like being blinded, frightened, or invisible.

Movement

Source Player Core pg. 398
Your Speed (page 420) governs how far you can move. Stride (page 418) is an action that has the move trait and allows you to move a number of feet up to your Speed. You may need to Stride multiple times in a turn! Move actions can often trigger reactions or free actions. However, unlike other actions, a move action can trigger reactions not only when you first use the action, but also for every 5 feet you move during that action (page 422). The Step action (page 418) lets you move without triggering reactions, but only 5 feet. Other basic actions with the move trait include Crawl, Drop Prone, and Stand (page 418).

This game measures movement on a grid (page 421). Difficult terrain and other types of terrain (page 423) may impede your movement.

Creatures can get tactical advantages by careful positioning. The most common are using cover from terrain and other creatures to increase your AC (page 424), and flanking (page 425), which requires you and an ally to be on the opposite sides of an enemy to reduce the enemy's AC.

Attacking

Source Player Core pg. 398
Strike (page 418) actions have the attack trait and allow you to attack with a weapon you're wielding or an unarmed attack (such as a fist). If you're using a melee weapon or unarmed attack, your target must be within your reach (page 426); if you're attacking with a ranged weapon, your target must be within your range (page 526). Ranged weapons get less effective as you exceed their range increments (page 403). Striking multiple times in a turn has diminishing returns. A multiple attack penalty (page 402) applies to each attack after the first.

Defenses

Source Player Core pg. 399
Your Armor Class (AC) (page 404) is the main DC used for attacks against you. You might also roll a type of check called a saving throw (page 404), also called a save, against spells, afflictions, and a wide variety of other effects. There are three kinds of saving throw: Fortitude, Reflex, and Will.

Damage

Source Player Core pg. 399
Attacks, spells, and other dangers deal damage (page 406). The amount is typically determined by a damage roll (page 406), which can use a variety of sizes and numbers of dice.

Damage reduces the Hit Points (HP) (page 410) that measure a creature's overall health or an object's durability. A creature might have immunity to damage or effects of certain kinds, a resistance that reduces the damage it takes, or a weakness that increases damage it takes (page 408). These are typically keyed to damage types (page 409) such as slashing damage or fire damage.

Related: Persistent damage condition (page 445)

Spells

Source Player Core pg. 399
Most of the rules for casting spells are in Chapter 7 (pages 296–303). For a spell that requires an attack roll against the target's AC, you'll calculate your spell attack modifier (page 403). For one that causes its subject to attempt a saving throw, you'll need your spell DC (page 403).

Related: Dismiss and Sustain basic actions (419)

Skills

Source Player Core pg. 399
Skill checks are required for all sorts of other tasks related to adventuring and life in general. Most of their rules are in Chapter 4 (page 224). You'll find the rules for calculating skill modifiers on page 226. Many exploration activities (page 438), such as Avoid Notice and Investigate, also use skill checks.

Perception and Detection

Source Player Core pg. 399
Your Perception modifier (page 404) indicates how good you are at noticing things around you. You typically use the Seek basic action (page 417) to find physical things or the Sense Motive basic action (page 417) in social situations. While in exploration mode, the Search activity (page 439) lets you keep an eye out for things around you.

Four main conditions indicate how well you can pinpoint and target a creature: observed, hidden, undetected, and unnoticed (page 434). A creature with the concealed or invisible condition is harder to find and target (page 442).

Related: Light (page 432), special senses (page 433)

Checks

Source Player Core pg. 400
When success isn't certain—whether you're swinging a sword at a foul beast, attempting to leap across a chasm, or straining to remember the name of the earl's second cousin at a soiree—you'll attempt a check.

All types of checks, from skill checks to attack rolls to saving throws, follow these basic steps.
  • Roll a d20 and identify the modifiers, bonuses, and penalties that apply.
  • Calculate the result.
  • Compare to the DC.
  • Determine the degree of success and the effect.
Checks and Difficulty Classes (DC) both come in many forms. When you swing your sword at that foul beast, you make an attack roll against its Armor Class, which is the DC to hit another creature. As you try to leap across that chasm, you'll attempt an Athletics skill check with a DC based on the distance you're trying to jump. When calling to mind the name of the earl's second cousin, you attempt a check to Recall Knowledge. You might use either the Society skill or a Lore skill you have that's relevant to the task, and the DC depends on how common the knowledge of the cousin's name might be, or possibly how many drinks your character had when they were introduced to the cousin the night before.

No matter the details, for any check you must roll the d20 and achieve a result equal to or greater than the DC to succeed. Each of these steps is explained below.

Step 1: Roll D20

Source Player Core pg. 400
Start by rolling your d20. You'll then identify all the relevant modifiers, bonuses, and penalties that apply. A modifier can be either positive or negative, but a bonus is always positive, and a penalty is always negative. The sum of all the modifiers, bonuses, and penalties you apply to the d20 roll is called your total modifier for that statistic.

Attribute Modifier

Source Player Core pg. 400
Nearly all checks allow you to add an attribute modifier to the roll. Attribute modifiers represent your raw capability and are described on page 19. Exactly which attribute modifier you use is determined by what you're trying to accomplish. Usually, a sword swing applies your Strength modifier, whereas remembering the name of the earl's cousin uses your Intelligence modifier.

Bonuses

Source Player Core pg. 400
When attempting a check that involves something you have some training in, you will also add your proficiency bonus. This bonus depends on your proficiency rank: untrained, trained, expert, master, or legendary. If you're untrained, your bonus is +0—you must rely on raw talent and any bonuses from the situation. Otherwise, the bonus equals your character's level plus a certain amount depending on your rank. If your proficiency rank is trained, this bonus is equal to your level + 2, and higher proficiency ranks further increase the amount you add to your level.

Proficiency Bonus

Proficiency RankProficiency Bonus
Untrained0
TrainedYour level + 2
ExpertYour level + 4
MasterYour level + 6
LegendaryYour level + 8

There are three other types of bonus that frequently appear: circumstance bonuses, item bonuses, and status bonuses. If you have different types of bonuses that would apply to the same roll, you'll add them all. But if you have multiple bonuses of the same type, you can use only the highest bonus on a given roll—they aren't cumulative. For instance, if you have both a proficiency bonus and an item bonus, you add both to your d20 result, but if you have two item bonuses, you add only the higher of the two.

Circumstance bonuses involve the situation you find yourself in when attempting a check. For instance, using Raise a Shield with a buckler grants you a +1 circumstance bonus to AC. Being behind cover grants you a +2 circumstance bonus to AC.

Item bonuses are granted by some item that you are wearing or using, either mundane or magical. For example, armor gives you an item bonus to AC, while an expanded alchemist's toolkit grants you an item bonus to Crafting checks when making alchemical items.

Status bonuses typically come from spells, other magical effects, or something applying a helpful, often temporary, condition to you. For instance, the 3rd-rank heroism spell grants a +1 status bonus to attack rolls, Perception checks, saving throws, and skill checks.

Penalties

Source Player Core pg. 400
Penalties work very much like bonuses. You can have circumstance penalties, status penalties, and sometimes even item penalties. Like bonuses of the same type, you take only the worst all of various penalties of a given type. However, you can apply both a bonus and a penalty of the same type on a single roll. For example, if you had a +1 status bonus from a heroism spell but a –2 status penalty from the sickened condition, you'd apply them both to your roll—so heroism still helps even though you're feeling unwell.

Unlike bonuses, penalties can also be untyped, in which case they won't be classified as “circumstance,” “item,” or “status.” Unlike other penalties, you always add all your untyped penalties together rather than simply taking the worst one. For instance, when you use attack actions, you incur a multiple attack penalty on each attack you make on your turn after the first attack of the turn, and when you attack a target that's beyond your weapon's normal range increment, you incur a range penalty on the attack. Because these are both untyped penalties, if you make multiple attacks at a faraway target, you'd apply both the multiple attack penalty and the range penalty to your roll.

Once you've identified all your various modifiers, bonuses, and penalties, you move on to the next step.

Step 2: Calculate Result

Source Player Core pg. 401
This step is simple. Add up all the various modifiers, bonuses, and penalties you identified in Step 1—this is your total modifier. Next add that to the number that came up on your d20 roll. This total is your check result.

Step 3: Compare to DC

Source Player Core pg. 401
Whenever you attempt a check, you compare your result against the Difficulty Class (DC) of the check. Your check succeeds if it's equal to or greater than the DC. If you roll anything less than the DC, you fail.

Sometimes you'll know the DC and make the comparison yourself. Other times, you might not know the DC right away. Swimming across a river would require an Athletics check, but it doesn't have a specified DC—so how will you know if you succeed or fail? You call out your result to the GM and they'll let you know if it's a success, failure, or otherwise. While you might learn the exact DC through trial and error, DCs sometimes change, so asking the GM whether a check is successful is best.

Getting a DC from a Modifier

Source Player Core pg. 401
When someone attempts a check against you, you might need to defend with one of your statistics that’s normally a modifier, such as your “Reflex DC.” Rather than rolling a check of your own, you need to generate a fixed DC based on your modifier. Your DC for a given statistic is 10 + the total modifier for that statistic. So if you have a +4 Reflex save, your Reflex DC is 14.

Step 4: Degree of Success

Source Player Core pg. 401
Many times, it's important to determine not only if you succeed or fail, but also how spectacularly you succeed or fail. Exceptional results—either good or bad—can cause you to critically succeed or critically fail at a check.

You critically succeed when the check's result meets or exceeds the DC by 10 or more. If the check is an attack roll, this is also known as a critical hit. You can also critically fail a check. The rules for critical failure—sometimes called a fumble—are the same as those for a critical success, but in the other direction: if you fail a check by 10 or more, that's a critical failure.

Some actions and abilities have stronger effects on a critical success or failure. For example, a Strike deals double damage on a critical hit. If an effect doesn't list a critical success effect, the critical success effect is the same as the success effect, and the same goes for critical failures.

Natural 1 and Natural 20

Source Player Core pg. 401
If you rolled a 20 on the die (a “natural 20”), your result is one degree of success better than it would be by numbers alone. If you roll a 1 on the d20 (a “natural 1”), your result is one degree worse. This means that a natural 20 usually results in a critical success and natural 1 usually results in a critical failure. However, if you were going up against a very high DC, you might get only a success with a natural 20, or even a failure if 20 plus your total modifier is 10 or more below the DC. Likewise, if your modifier for a statistic is so high that adding it to a 1 from your d20 roll exceeds the DC by 10 or more, you can succeed even if you roll a natural 1!

Certain abilities can change the degree of success on a roll. When resolving such an ability, apply the adjustment from a natural 20 or natural 1 before anything else.

Attack Rolls

Source Player Core pg. 402
When you use a Strike action or make a spell attack, you attempt a check called an attack roll. Attack rolls take a variety of forms and are often highly variable based on the weapon you are using for the attack, but there are three main types: melee attack rolls, ranged attack rolls, and spell attack rolls. Spell attack rolls work a little bit differently, so they are explained separately on the next page.

Melee attack rolls use Strength as their attribute modifier by default. If you're using a weapon or attack with the finesse trait, then you can use your Dexterity modifier instead.

Melee attack roll result = d20 roll + Strength modifier (or optionally Dexterity modifier for a finesse weapon) + proficiency bonus + other bonuses + penalties

Ranged attack rolls use Dexterity as their attribute modifier.

Ranged attack roll result = d20 roll + Dexterity modifier + proficiency bonus + other bonuses + penalties

When attacking with a weapon, whether melee or ranged, you add your proficiency bonus for the weapon you're using. Your class determines your proficiency rank for various weapons. Sometimes, you'll have different proficiency ranks for different weapons or groups of weapons.

The bonuses you might apply to attack rolls can come from a variety of sources. Circumstance bonuses can come from the aid of an ally or a beneficial situation. Status bonuses are typically granted by spells and other magical aids. The item bonus to attack rolls comes from magic weapons—notably, a weapon's potency rune (GM Core, page 236).

Penalties to attack rolls come from situations and effects as well. Circumstance penalties come from risky tactics or detrimental circumstances, status penalties come from spells and magic working against you, and item penalties occur when you use a shoddy item (page 270). When making attack rolls, two main types of untyped penalties are likely to apply. The first is the multiple attack penalty, and the second is the range penalty. The first applies anytime you make more than one attack action during the course of your turn, and the other applies only with ranged or thrown weapons. Both are described below.

Multiple Attack Penalty

Source Player Core pg. 402
The more attacks you make beyond your first in a single turn, the less accurate you become, represented by the multiple attack penalty. The second time you use an attack action during your turn, you take a –5 penalty to your check. The third time you attack, and on any subsequent attacks, you take a –10 penalty to your check. Every check that has the attack trait counts toward your multiple attack penalty, including Strikes, spell attack rolls, certain skill actions like Shove, and many others.

Some weapons and abilities reduce multiple attack penalties, such as agile weapons, which reduce these penalties to –4 on the second attack or –8 on further attacks.

Multiple Attack Penalty

AttackMultiple Attack PenaltyAgile
FirstNoneNone
Second-5-4
Third and subsequent-10-8

Always calculate your multiple attack penalty based on the weapon you're using on that attack, not ones you used on previous attacks. For example, let's say you're wielding a longsword in one hand and a shortsword (which has the agile trait) in your other hand, and you make three Strikes with these weapons over the course of your turn. The first Strike you make during your turn has no penalty, no matter what weapon you are using. The second Strike will take either a –5 penalty if you use the longsword or a –4 penalty if you use the shortsword. Your third attack would be a –10 penalty with the longsword and a –8 penalty with the shortsword, no matter what weapon you used for your previous Strikes.

The multiple attack penalty applies only during your turn, so you don't have to keep track of it if you can perform a Reactive Strike or a similar reaction that lets you make a Strike on someone else's turn.

Range Penalty

Source Player Core pg. 403
Ranged and thrown weapons each have a listed range increment, and attacks with them grow less accurate against targets farther away (range and range increments are covered in depth on page 426). As long as your target is at or within the listed range increment, also called the first range increment, you take no penalty to the attack roll. If you're attacking beyond that range increment, you take a –2 penalty for each additional increment beyond the first. You can attempt to attack with a ranged weapon or thrown weapon up to six range increments away, but the farther away you are, the harder it is to hit your target.

For example, the range increment of a crossbow is 120 feet. If you are shooting at a target no farther away than that distance, you take no penalty due to range. If they're beyond 120 feet but no more than 240 feet away, you take a –2 penalty due to range. If they're beyond 240 feet but no more than 360 feet away, you take a –4 penalty due to range, and so on, until you reach the last range increment: beyond 600 feet but no more than 720 feet away, where you take a –10 penalty due to range.

Compare to AC

Source Player Core pg. 403
You compare your attack roll to Armor Class (AC), a special type of DC. Learn how to calculate it on page 404.

Spell Attack Rolls

Source Player Core pg. 403
If you cast spells, you might need to make a spell attack roll. These rolls are usually made when you cast a spell that targets a creature's AC.

The attribute modifier for a spell attack roll depends on how you gained the spell. If your class grants you spellcasting, use your key attribute modifier (such as Intelligence for a wizard). Innate spells use your Charisma modifier unless the ability that granted them states otherwise. Focus spells and other sources of spells specify which attribute modifier you use for spell attack modifiers in the ability that granted them. If you have spells from multiple sources or traditions, you might use different attribute modifiers for spell attack modifiers for these different sources of spells. For example, a dwarf cleric with the Stonewalker ancestry feat would use her Charisma modifier when casting one with stone from that feat, since it's a divine innate spell, but she would use her Wisdom modifier when casting heal and other spells using her cleric divine spellcasting.

If you have the ability to cast spells, you'll have a proficiency rank for your spell attack modifier, so you'll always add a proficiency bonus. Spell attack rolls can benefit from circumstance bonuses and status bonuses, though item bonuses to spell attack rolls are rare. Penalties affect spell attack rolls just like any other attack roll—including your multiple attack penalty.

Calculate a spell attack roll with the following formula.

Spell attack roll result = d20 roll + spellcasting attribute modifier + proficiency bonus + other bonuses + penalties


Spell DC

Source Player Core pg. 403
Many times, instead of requiring you to make a spell attack roll, the spells you cast will require those within the area or targeted by the spell to attempt a saving throw against your spell DC to determine how the spell affects them. Calculate it using the following formula.

Spell DC = 10 + spellcasting attribute modifier + proficiency bonus + other bonuses + penalties


Defenses

Source Player Core pg. 404
Multiple statistics help you defend against attacks, spells, hazards, and other dangers of adventuring: Armor Class and three saving throws.

Armor Class

Source Player Core pg. 404
Attack rolls are compared to a special Difficulty Class called Armor Class (AC), which measures how hard it is for your foes to hit you with Strikes, spell attack rolls, and other attacks. Just like for any other check and DC, the result of an attack roll must meet or exceed your AC to be successful, which allows your foe to deal damage to you. Armor Class is calculated using the following formula.

Armor Class = 10 + Dexterity modifier (up to your armor's Dex Cap) + proficiency bonus + armor's item bonus to AC + other bonuses + penalties

Use your proficiency bonus for the category (light, medium, or heavy) or the specific type of armor you're wearing. If you're not wearing armor, use your proficiency in unarmored defense.

Armor Class can benefit from bonuses with a variety of sources, much like attack rolls. Armor itself grants an item bonus, so other item bonuses usually won't apply to your AC, but magic armor can increase the item bonus granted by your armor.

Penalties to AC come from situations and effects in much the same way bonuses do. Circumstance penalties come from unfavorable situations, and status penalties come from effects that impede your abilities or from broken armor. You take an item penalty when you wear shoddy armor (page 270).

Saving Throws

Source Player Core pg. 404
There are three types of saving throws: Fortitude saves, Reflex saves, and Will saves. These are frequently called “saves”—it's the same thing. Saving throws measure your ability to shrug off harmful effects in the form of afflictions, damage, or conditions. You'll always add a proficiency bonus to each save. Your class might give a different proficiency to each save, but you'll be trained at minimum. Some circumstances and spells might give you circumstance or status bonuses to saves, and you might find resilient armor or other magic items that give an item bonus.

Fortitude saving throws allow you to reduce the effects of abilities and afflictions that can debilitate the body. They use your Constitution modifier and are calculated as shown in the formula below.

Fortitude save result = d20 roll + Constitution modifier + proficiency bonus + other bonuses + penalties

Reflex saving throws measure how well you can respond quickly to a situation and how gracefully you can avoid effects that have been thrown at you. They use your Dexterity modifier and are calculated as shown in the formula below.

Reflex save result = d20 roll + Dexterity modifier + proficiency bonus + other bonuses + penalties

Will saving throws measure how well you can resist attacks to your mind and spirit. They use your Wisdom modifier and are calculated as shown in the formula below.

Will save result = d20 roll + Wisdom modifier + proficiency bonus + other bonuses + penalties

Sometimes you'll need to know your DC for a given saving throw (such as a Grapple attempt requiring a roll against your Reflex DC). Like any other DC derived from a modifier, the DC for a saving throw is 10 + the total modifier for that saving throw.

Most of the time, when you attempt a saving throw, you don't have to use your actions or your reaction. You don't even need to be able to act to attempt saving throws. However, in some special cases you might have to take an action to attempt a save. For instance, you can try to recover from the sickened condition by spending an action to attempt a Fortitude save.

Basic Saving Throws

Source Player Core pg. 404
Sometimes you will be called on to attempt a basic saving throw (or “basic save”). This type of saving throw works just like any other saving throw—the “basic” part refers to the effects. For a basic save, you'll attempt the check and determine whether you critically succeed, succeed, fail, or critically fail like you would any other saving throw. Then one of the following outcomes applies based on your degree of success—no matter what caused the saving throw. Some spells or abilities add an additional effect on certain results but still use a basic saving throw for brevity.

Critical Success You take no damage from the effect.
Success You take half the listed damage from the effect.
Failure You take the full damage listed from the effect.
Critical Failure You take double the listed damage from the effect.

Perception

Source Player Core pg. 404
Perception measures your ability to be aware of your environment. Every creature has Perception, which works with and is limited by a creature's senses. (Details on senses and detecting things are on page 434). Whenever you need to attempt a check based on your awareness, you'll attempt a Perception check. Your Perception uses your Wisdom modifier, so you'll use the following formula when attempting a Perception check.

Perception check result = d20 roll + Wisdom modifier + proficiency bonus + other bonuses + penalties

Nearly all creatures are at least trained in Perception, so you will almost always add a proficiency bonus to your Perception modifier. You might add a circumstance bonus for advantageous situations or environments and typically get status bonuses from spells or other magical effects. Items can also grant you a bonus to Perception, typically in a certain situation. For instance, a fine spyglass grants a +1 item bonus to Perception when attempting to see something a long distance away. Circumstance penalties to Perception occur when an environment or situation (such as fog) hampers your senses, while status penalties typically come from conditions, spells, and magic effects that foil the senses. You'll rarely encounter item penalties or untyped penalties for Perception.

Many abilities are compared to your Perception DC to determine whether they succeed. As with any DC based on a modifier, your Perception DC is 10 + your total Perception modifier.

Perception for Initiative

Source Player Core pg. 405
Often, you’ll roll a Perception check to determine your order in initiative. When you do this, instead of comparing the result against a DC, the GM will put the results for everyone in the encounter in order. The creature with the highest result acts first, the creature with the second-highest result goes second, and so on. Sometimes you may be called on to roll a skill check for initiative instead, but you’ll compare results just as if you had rolled Perception. The full rules for initiative are found in the rules for encounter mode on page 435.

Skill Checks

Source Player Core pg. 405
Pathfinder has a variety of skills, from Athletics to Medicine to Occultism. Each grants you a set of related actions that rely on you rolling a skill check. Each skill has a key attribute modifier, based on the scope of the skill in question. For instance, Athletics deals with feats of physical prowess, like swimming and jumping, so its key attribute modifier is Strength. Medicine deals with the ability to diagnose and treat wounds and ailments, so its key attribute modifier is Wisdom. The key attribute modifier for each skill is listed on page 227 in Chapter 4: Skills. No matter which skill you're using, you calculate a check for it using the following formula.

Skill check result = d20 roll + the skill's key attribute modifier + proficiency bonus + other bonuses + penalties

You're unlikely to be trained in every skill. As normal, when using a skill in which you're untrained, your proficiency bonus is +0; otherwise, it equals your level plus 2 for trained, or higher once you become expert or better. The proficiency rank is specific to the skill you're using. Aid from another character or some other beneficial situation may grant you a circumstance bonus. A status bonus might come from a helpful spell or magical effect. Sometimes tools related to the skill grant you an item bonus to your skill checks. Conversely, unfavorable situations might give you a circumstance penalty to your skill check, while harmful spells, magic, or conditions might also impose a status penalty. Using shoddy or makeshift tools might cause you to take an item penalty. Sometimes a skill action can be an attack, and in these cases, the skill check might take a multiple attack penalty, as described on page 234.

When an ability calls for you to use the DC for a specific skill, you can calculate it by adding 10 + your total modifier for that skill.

Damage Rolls

Source Player Core pg. 406
Strikes, spells, hazards, and all number of other dangers can deal damage, which can kill creatures and destroy objects.

Damage decreases a creature's Hit Points (HP) on a 1-to- 1 basis (so a creature that takes 6 damage loses 6 Hit Points). The full rules for losing HP can be found in the Hit Points, Healing, and Dying section on page 410.

Damage is sometimes given as a fixed amount, but more often than not you'll make a damage roll to determine how much damage you deal. A damage roll typically uses a number and type of dice determined by the weapon or unarmed attack used or the spell cast, and it's often enhanced by various modifiers, bonuses, and penalties. Like checks, a damage roll—especially a melee weapon damage roll—is often modified by a number of modifiers, penalties, and bonuses. When making a damage roll, you take the following steps, explained in detail below.
  • Roll damage dice indicated by the weapon, unarmed attack, or spell, and apply the modifiers, bonuses, and penalties that apply to the result of the roll.
  • Determine the damage type.
  • Apply immunities, weaknesses, and resistances the subject has to the damage.
  • If any damage remains, reduce Hit Points the target has by that amount.

Step 1: Roll Damage Dice

Source Player Core pg. 406
Your weapon, unarmed attack, spell, or even a magic item determines what size and number of dice you roll for damage. For instance, if you're using a normal longsword, you'll roll 1d8. If you're casting a 3rd-rank fireball spell, you'll roll 6d6. Sometimes, especially in the case of weapons, you'll apply modifiers, bonuses, and penalties to the damage.

Damage rolls for melee weapons and unarmed attacks typically add your Strength attribute modifier.

Melee damage roll = damage die of weapon or unarmed attack + Strength modifier + bonuses + penalties

Damage rolls for ranged weapons typically don't add an attribute modifier, though you add your Strength modifier to damage rolls for thrown weapons or half the modifier to damage rolls for ranged weapons with the propulsive trait.

Ranged damage roll = damage die of weapon (+ Strength modifier for a thrown weapon or half Strength modifier for a propulsive weapon) + bonuses + penalties

For damage rolls with spells, alchemical bombs, and similar items, you don't add an attribute modifier unless otherwise noted.

Spell (or similar effect) damage roll = damage die of effect + bonuses + penalties

As with checks, you might add circumstance, status, or item bonuses to your damage rolls, but if you have multiple bonuses of the same type, you add only the highest bonus of that type. Again like checks, you may also apply circumstance, status, item, and untyped penalties to the damage roll, and again you apply only the greatest penalty of a specific type but apply all untyped penalties together.

If the combined penalties on an attack would reduce the damage to 0 or below, you still deal 1 damage. Sometimes there are other considerations, described below.

Adding Damage Dice

Source Player Core pg. 406
Each weapon lists the damage die used for its damage roll. A standard weapon deals one die of damage, but a magical striking rune can increase the number of dice rolled, as can some special actions and spells. These additional dice use the same die size as the weapon or unarmed attack's normal damage die.

Counting Damage Dice

Source Player Core pg. 406
Effects based on a weapon's number of damage dice include only the weapon's damage die plus any extra dice from a striking rune. They don't count extra dice from abilities, critical specialization effects, property runes, weapon traits, or the like.

Increasing Die Size

Source Player Core pg. 406
When an effect calls on you to increase the size of your weapon damage dice, instead of using its normal weapon damage dice, use the next larger die, as listed below (so if you were using a d4, you'd use a d6, and so on). If you are already using a d12, the size is already at its maximum. You can't increase your weapon damage die size more than once.

1d4 » 1d6 » 1d8 » 1d10 » 1d12


Persistent Damage

Source Player Core pg. 406
Persistent damage is a condition that causes damage to recur beyond the original effect. Like normal damage, it can be doubled or halved based on the results of an attack roll or saving throw. Unlike with normal damage, when you are subject to persistent damage, you don’t take it right away. Instead, you take the specified damage at the end of your turns, after which you attempt a DC 15 flat check to see if you recover from the persistent damage. See page 445 in the Conditions Appendix for the complete rules regarding the persistent damage condition.

Doubling and Halving Damage

Source Player Core pg. 407
Sometimes you'll need to halve or double an amount of damage, such as when the outcome of your Strike is a critical hit or when you succeed at a basic Reflex save against a spell. When this happens, you roll the damage normally, adding all the normal modifiers, bonuses, and penalties. Then you double or halve the amount as appropriate. As normal, round down if you halve the damage (though 1 damage halved remains at a minimum of 1 damage).

When doubling, the GM might allow you to roll the dice twice and double the modifiers, bonuses, and penalties instead of doubling the entire result, but this usually works best for single-target attacks or spells at low levels when you have a small number of damage dice to roll. Benefits you gain specifically from a critical hit, like the extra damage die from the fatal weapon trait, aren't doubled.

Step 2: Damage Type

Source Player Core pg. 407
Once you've calculated how much damage you deal, you'll need to determine the damage type. The smack of a club deals bludgeoning damage. The shock of a lightning bolt spell deals electricity damage. Sometimes you might apply precision damage, dealing more damage for hitting a creature in a vulnerable spot or when the target is somehow vulnerable. The damage types are described on page 409.

Step 3: Apply Immunities, Weaknesses, and Resistances

Source Player Core pg. 407
Defenses against certain types of damage or effects are called immunities or resistances, while vulnerabilities are called weaknesses. Apply immunities first, then weaknesses, and resistances third. See page 408.

Step 4: Reduce Hit Points

Source Player Core pg. 407
Any remaining damage reduces the target’s Hit Points on a 1-to-1 basis. More information can be found in the Hit Points, Healing, and Dying section on page 410.

Nonlethal Attacks

Source Player Core pg. 407
You can make a nonlethal attack to knock someone out instead of killing them (see Knocked Out and Dying on page 410). Weapons with the nonlethal trait (including fists) do this automatically. You take a –2 circumstance penalty to the attack roll when you make a nonlethal attack using a weapon or unarmed attack that doesn’t have the nonlethal trait. You also take this penalty when making a lethal attack using a nonlethal weapon. Spells and other effects with the nonlethal trait that reduce a creature to 0 Hit Points knock the creature out instead of killing them.

Immunity, Weakness, and Resistance

Source Player Core pg. 408
Damage and effects can be negated, deal less damage, or deal more damage due to the recipient’s immunity, weakness, or resistance.

Immunity

Source Player Core pg. 408
When you have immunity to a specific type of damage, you ignore all damage of that type. If you have immunity to a specific condition or type of effect, you can't be affected by that condition or any effect of that type. You can still be targeted by an ability that includes an effect or condition you are immune to; you just don't apply that particular effect or condition.

If you have immunity to effects with a certain trait (such as death effects, poison, or disease), you are unaffected by effects with that trait. Often, an effect both has a trait and deals that type of damage (such as a lightning bolt spell). In these cases, the immunity applies to the effect corresponding to the trait, not just the damage. However, some complex effects might have parts that affect you even if you're immune to one of the effect's traits; for instance, a spell that deals both fire and acid damage can still deal acid damage to you even if you're immune to fire.

Immunity to Critical Hits

Source Player Core pg. 408
Immunity to critical hits works a little differently. When a creature immune to critical hits is critically hit by a Strike or other attack that deals damage, it takes normal damage instead of double damage. This does not make it immune to any other critical success effects of the actions, such as a critical specialization effect or the extra damage of the deadly trait. However, in some cases the GM might determine the added effects don’t apply.

Immunity to Nonlethal

Source Player Core pg. 408
Another exception is immunity to the nonlethal trait. If you’re immune to nonlethal, you’re immune to all damage from attacks and effects with the nonlethal trait, no matter what other type the damage has. For instance, a typical construct has immunity to nonlethal attacks. No matter how hard you hit it with your fist, you’re not going to damage it. However, you can take a penalty to remove the nonlethal trait from your fist (page 282), and some abilities give you unarmed attacks without the nonlethal trait.

Temporary Immunity

Source Player Core pg. 408
Some effects grant you immunity to the same effect for a set amount of time. If an effect grants you temporary immunity, repeated applications of that effect don't affect you for as long as the temporary immunity lasts. Unless the effect says it applies only to a certain creature's ability, it doesn't matter who created the effect. For example, the blindness spell says, “The target is temporarily immune to blindness for 1 minute.” If anyone casts blindness on that creature again before 1 minute passes, the spell has no effect.

Temporary immunity doesn't prevent or end ongoing effects of the source of the temporary immunity. For instance, if an ability makes you frightened and you then gain temporary immunity to the ability, you don't immediately lose the frightened condition due to the immunity you just gained—you simply don't become frightened if you're targeted by the ability again before the immunity ends.

Weakness

Source Player Core pg. 408
If you have a weakness to a certain type of damage or damage from a certain source, that type of damage is extra effective against you. Whenever you would take that type of damage, increase the damage you take by the value of the weakness. For instance, if you are dealt 2d6 fire damage and have weakness 5 to fire, you take 2d6+5 fire damage.

If you have a weakness to something that doesn't normally deal damage, such as water, you take damage equal to the weakness value when touched or affected by it. If more than one weakness would apply to the same instance of damage, use only the highest applicable weakness value. This usually only happens when a creature is weak to both a type of damage and a material or trait, such as a cold iron axe cutting a monster that has weakness to cold iron and slashing.

Resistance

Source Player Core pg. 408
If you have resistance to a type of damage, each time you take that type of damage, reduce the amount of damage you take by the listed number (to a minimum of 0 damage).

Resistance can specify combinations of damage types or other traits. For instance, you might encounter a monster that's resistant to non-magical bludgeoning damage, meaning it would take less damage from bludgeoning attacks that weren't magical, but would take normal damage from your +1 mace (since it's magical) or a nonmagical spear (since it deals piercing damage). A resistance also might have an exception. For example, resistance 10 to physical damage (except silver) would reduce any physical damage by 10 unless that damage was dealt by a silver weapon.

If you have more than one type of resistance that would apply to the same instance of damage, use only the highest applicable resistance value, as described in weakness.

It's possible to have resistance to all damage. When an effect deals damage of multiple types and you have resistance to all damage, apply the resistance to each type of damage separately. If an attack would deal 7 slashing damage and 4 fire damage, resistance 5 to all damage would reduce the slashing damage to 2 and negate the fire damage entirely.

Hit Points, Healing, and Dying

Source Player Core pg. 410
For adventurers, injury and death lurk around every corner.

Hit Points

Source Player Core pg. 410
All creatures and objects have Hit Points (HP). Your maximum Hit Point value represents your health, wherewithal, and heroic drive when you're in good health and rested. Your maximum Hit Points include the Hit Points you gain at 1st level from your ancestry and class, those you gain at higher levels from your class, and any you gain from other sources (like the Toughness general feat). When you take damage, you reduce your current Hit Points by a number equal to the damage dealt.

Some spells, items, and other effects, as well as simply resting, can heal creatures. When you're healed, you regain Hit Points equal to the amount healed, up to your maximum Hit Points.

Temporary Hit Points

Source Player Core pg. 410
Some spells or abilities give you temporary Hit Points. Track these separately from your current and maximum Hit Points; when you take damage, reduce your temporary Hit Points first. Most temporary Hit Points last for a limited duration. You can’t regain lost temporary Hit Points through healing, but you can gain more via other abilities. You can have temporary Hit Points from only one source at a time. If you gain temporary Hit Points when you already have some, choose whether to keep the amount you already have and their corresponding duration or to gain the new temporary Hit Points and their duration.

Fast Healing and Regeneration

Source Player Core pg. 410
A creature with fast healing or regeneration regains the listed amount of Hit Points each round at the beginning of its turn. A creature with regeneration has additional benefits. Its dying condition can’t increase to a value that would kill it (this stops most creatures from going beyond dying 3) as long as its regeneration is active. If it takes damage of a type listed in the regeneration entry, its regeneration deactivates until the end of its next turn.

Items and Hit Points

Source Player Core pg. 410
Items have Hit Points like creatures, but the rules for damaging them are different, as explained on page 269. An item has a Hardness statistic that reduces damage the item takes by that amount. The item then takes any damage left over. If an item is reduced to 0 HP, it’s destroyed. An item also has a Broken Threshold. If its HP are reduced to this amount or lower, it’s broken, meaning it can’t be used for its normal function and it doesn’t grant bonuses. You usually can’t attack an attended object (one on a creature’s person).

Getting Knocked Out

Source Player Core pg. 410
Creatures can't be reduced to fewer than 0 Hit Points. When most creatures reach 0 Hit Points, they die and are removed from play unless the attack was nonlethal, in which case they're instead knocked out for a significant amount of time (usually 10 minutes or more). When undead and constructs reach 0 Hit Points, they're destroyed.

Player characters, their companions, and other significant characters and creatures don't automatically die when they reach 0 Hit Points. Instead, they are knocked out and are at risk of death. The GM might determine that villains, powerful monsters, special NPCs, and enemies with special abilities that are likely to bring them back to the fight (like ferocity, regeneration, or healing magic) can use these rules as well.

As a player character, when you're reduced to 0 Hit Points, you're knocked out with the following effects:
  • Move your initiative position to directly before the turn in which you were reduced to 0 HP.
  • Gain the dying 1 condition. If the effect that knocked you out was a critical success from the attacker or the result of your critical failure, you gain the dying 2 condition instead. If you have the wounded condition, increase your dying value by an amount equal to your wounded value. If the damage was dealt by a nonlethal attack or nonlethal effect, you don't gain the dying condition; you're instead unconscious with 0 Hit Points.

Dying

Source Player Core pg. 411
While you have the dying condition, you’re bleeding out or otherwise at death’s door. You’re unconscious while you have the dying condition. Dying always includes a value. If this value ever reaches dying 4, you die. While you’re dying, your dying value can increase or decrease in two ways.

Recovery Checks

Source Player Core pg. 411
While you're dying, attempt a recovery check at the start of each of your turns. This is a flat check with a DC equal to 10 + your current dying value to see if you get better or worse.

Critical Success Your dying value is reduced by 2.
Success Your dying value is reduced by 1.
Failure Your dying value increases by 1.
Critical Failure Your dying value increases by 2.

Taking Damage

Source Player Core pg. 411
If you take damage while you already have the dying condition, increase your dying condition value by 1, or by 2 if the damage came from an attacker’s critical hit or your own critical failure.

Losing the Dying Condition

Source Player Core pg. 411
You lose the dying condition if it ever reaches dying 0. If you're still at 0 Hit Points, you remain unconscious, but you can wake up as described in that condition. You lose the dying condition automatically and wake up if you ever have 1 Hit Point or more.

Anytime you lose the dying condition, you gain the wounded 1 condition, or increase your wounded value by 1 if you already have that condition.

Death

Source Player Core pg. 411
After you die, you can’t act or regain actions, can’t be affected by spells that target creatures (unless they specifically target dead creatures), and for all other purposes, you’re an object. When you die, you’re reduced to 0 Hit Points if you had a different amount, and you can’t be brought above 0 Hit Points as long as you remain dead. Some magic can bring creatures back to life, such as the resurrect ritual or the raise dead spell, though these abilities aren’t without their risks or effects, and rare artifacts and powers can even interfere with them.

Instant Death

Source Player Core pg. 411
There are ways in which you can die instantly, without reaching dying 0 first.

Death Effects

Source Player Core pg. 412
Some spells and abilities can kill you immediately or bring you closer to death without needing to reduce you to 0 Hit Points first. These abilities have the death trait and usually involve energy from the Void, the antithesis of life, or other effects that target the mind or soul. If you're reduced to 0 Hit Points by a death effect, you're slain instantly without needing to reach dying 4. For instance, the vision of death spell automatically kills those it reduces to 0 Hit Points as terrifying hallucinations cause them to drop dead.

A death effect might state that it kills you outright, without dealing damage, in which case you die without having to first reach dying 4 or be reduced to 0 Hit Points. For instance, the Grim Reaper, an extremely powerful entity of death, can automatically slay creatures who fail their save against its death strike ability.

Massive Damage

Source Player Core pg. 412
You die instantly if you ever take damage equal to or greater than double your maximum Hit Points in one blow.

Hero Points

Source Player Core pg. 413
Your heroic deeds earn you Hero Points, which grant you good fortune or let you recover from the brink of death. Unlike most aspects of your character, which persist over the long term, Hero Points last for only a single session.

The GM is in charge of awarding Hero Points. Usually, each character gets 1 Hero Point at the start of a session and can gain more later by performing heroic deeds—something selfless, daring, or beyond normal expectations. You can have a maximum of 3 Hero Points at a time, and you lose any remaining Hero Points at the end of a session.

You can spend your Hero Points in one of two ways. Neither of these is an action, and you can spend Hero Points even if you aren't able to act. You can spend a Hero Point on behalf of your familiar or animal companion.
  • Spend 1 Hero Point to reroll a check. You must use the second result. This is a fortune effect (which means you can't use more than 1 Hero Point on a check).
  • Spend all your Hero Points (minimum 1) to avoid death. You can do this when your dying condition would increase. You lose the dying condition entirely and stabilize with 0 Hit Points. You don't gain the wounded condition or increase its value from losing the dying condition in this way, but if you already had that condition, you don't lose it or decrease its value.

Describing Heroic Deeds

Source Player Core pg. 413
Because spending Hero Points reflects heroic deeds or tasks that surpass normal expectations, if you spend a Hero Point, you should describe the deed or task your character accomplishes with it to the other players.

Your character's deed might invoke a lesson learned in a past adventure, could be spurred by a determination to save someone else, or might depend on an item that ended up on their person due to a previous exploit. If you don't want to describe the deed or don't have any strong ideas about how to do so, ask the GM to come up with something for you. This can be a collaborative process, too. The GM might remind you of a long-forgotten event in the campaign, and all you have to do is fill in how that event comes to mind just at the right time, motivating you to push past your limits.

Actions

Source Player Core pg. 414
You affect the world around you primarily by using actions, which produce effects. Actions are most closely measured and restricted during the encounter mode of play, but even when it isn't important for you to keep strict track of actions, they remain the way in which you interact with the game world.

You will need to track your actions carefully in an encounter. At the start of each turn you take in an encounter, you regain 3 actions and 1 reaction to spend that round. (Regaining your actions is described in detail on page 435.) You can spend your actions in many different ways.

There are four types of actions: single actions, activities, reactions, and free actions.

Single actions can be completed in a very short time. They're self-contained, and their effects are generated within the span of that single action.

Activities usually take longer and require using multiple actions, which must be spent in succession. Stride is a single action, but Sudden Charge is an activity in which you use both the Stride and Strike actions to generate its effect.

Reactions have triggers, which must be met for you to use the reaction. You can use a reaction anytime its trigger is met, whether it's your turn or not. Outside of encounters, your use of reactions is more flexible and up to the GM. Reactions are usually triggered by other creatures or by events outside your control.

Free actions don't cost you any of your actions per turn, nor do they cost your reaction. A free action with no trigger follows the same rules as a single action (except the action cost). It must be used on your turn and can't be used during another action. A free action with a trigger follows the same rules as a reaction (except the reaction cost). It can be used any time its trigger is met.

Action Icon Key

These icons appear in stat blocks as shorthand for each type of action. As a player, you'll usually see the icon in an action's header (such as in a basic action, skill action, feat, or spell). In a creature stat block, or a feat that gives you a new action in addition to other benefits, the icon will appear in the running text. For examples, see the formatting of rules on page 15.

Activities

Source Player Core pg. 414
An activity typically involves using multiple actions to create an effect greater than you can produce with a single action, or combining multiple single actions to produce an effect that's different from merely the sum of those actions. In some cases, usually when spellcasting, an activity can consist of only 1 action, 1 reaction, or even 1 free action.

An activity might cause you to use specific actions within it. You don't have to spend additional actions to perform them—they're already factored into the activity's required actions. (See Subordinate Actions on page 415.)

You have to spend all the actions of an activity at once to gain its effects. In an encounter, this means you must complete it during your turn. If an activity gets interrupted or disrupted in an encounter (page 415), you lose all the actions you committed to it.

Exploration and Downtime Activitie

Source Player Core pg. 414
Outside of encounters, activities can take minutes, hours, or even days. These activities usually have the exploration or downtime trait to indicate they're meant to be used during these modes of play. You can often do other things off and on as you carry out these activities, provided they aren't significant activities of their own. For instance, if you're Repairing an item, you might stretch your legs or have a brief discussion, but you couldn't Decipher Writing at the same time.

If an activity outside of an encounter is interrupted or disrupted, as described in Disrupting Actions on page 415, you usually lose the time you put in, but no additional time.

Actions with Triggers

Source Player Core pg. 414
You can use free actions that have triggers and reactions only in response to certain events. Each such reaction and free action lists the trigger that must happen for you to perform it. When its trigger is satisfied—and only when it is satisfied—you can use the reaction or free action, though you don't have to use the action if you don't want to.

There are only a few basic reactions and free actions that all characters can use. You're more likely to gain actions with triggers from your class, feats, and magic items.Outside of encounters, activities can take minutes, hours, or even days. These activities usually have the exploration or downtime trait to indicate they're meant to be used during these modes of play. You can often do other things off and on as you carry out these activities, provided they aren't significant activities of their own. For instance, if you're Repairing an item, you might stretch your legs or have a brief discussion, but you couldn't Decipher Writing at the same time.

If an activity outside of an encounter is interrupted or disrupted, as described in Disrupting Actions on page 415, you usually lose the time you put in, but no additional time.

Limitations on Triggers

Source Player Core pg. 414
The triggers listed in the stat blocks of reactions and some free actions limit when you can use those actions. You can use only one action in response to a given trigger. For example, if you had a reaction and a free action that both had a trigger of “your turn begins,” you could use either of them at the start of your turn—but not both. If two triggers are similar, but not identical, the GM determines whether you can use one action in response to each or whether they're effectively the same thing. Usually, this decision will be based on what's happening in the narrative.

This limitation of one action per trigger is per creature; more than one creature can use a reaction or free action in response to a given trigger. If multiple actions would be occurring at the same time, and it's unclear in what order they happen, the GM determines the order based on the narrative.

Other Actions

Source Player Core pg. 415
Sometimes you need to attempt something not already covered by defined actions in the game. When this happens, the rules tell you how many actions you need to spend, as well as any traits your action might have. For example, a spell that lets you switch targets might say you can do so “by spending a single action, which has the concentrate trait.” Game Masters can also use this approach when a character tries to do something that isn’t covered in the rules.

Gaining and Losing Actions

Source Player Core pg. 415
Effects can change the number of actions you can use on your turn, or whether you can use actions at all. The slowed condition, for example, causes you to lose actions, while the quickened condition causes you to gain them. Conditions are detailed in the appendix on pages 442–447. Whenever you lose a number of actions—whether from these conditions or in any other way—you choose which to lose if there's any difference between them. For instance, the haste spell makes you quickened, but it limits what you can use your extra action to do. If you lost an action while haste was active, you might want to lose the action from haste first, since it's more limited than your normal actions.

Some effects are even more restrictive. Certain abilities, instead of or in addition to changing the number of actions you can use, say specifically that you can't use reactions. The most restrictive form of reducing actions is when an effect states that you can't act: this means you can't use any actions, or even speak. When you can't act, you still regain your actions unless another effect (like the stunned condition) prevents it

Disrupting Actions

Source Player Core pg. 415
Various abilities and conditions, such as a Reactive Strike, can disrupt an action. When an action is disrupted, you still use the actions or reactions you committed and you still expend any costs, but the action's effects don't occur. In the case of an activity, you usually lose all actions spent for the activity up through the end of that turn. For instance, if you began to Cast a Spell requiring 3 actions and the first action was disrupted, you lose all 3 actions that you committed to that activity.

The GM decides what effects a disruption causes beyond simply negating the effects that would have occurred from the disrupted action. For instance, a Leap disrupted midway wouldn't transport you back to the start of your jump, and a disrupted item hand off might cause the item to fall to the ground instead of staying in the hand of the creature who was trying to give it away.

Basic Actions

Source Player Core pg. 416
Basic actions represent common tasks like moving around, attacking, and helping others. As such, every creature can use basic actions except in some extreme circumstances, and many of those actions are used very frequently. Most notably, you'll use Interact, Step, Stride, and Strike a great deal. Many feats and other actions call upon you to use one of these basic actions or modify them to produce different effects. For example, a more complex action might let you Stride twice, and a large number of activities include a Strike. An action or activity might also modify a basic action, such as having you Stride up to half your Speed.

Actions that are used less frequently but are still available to most creatures are presented in Specialty Basic Actions starting on page 418. These typically have requirements that not all characters are likely to meet, such as wielding a shield, having a burrow Speed, or falling through the air.

In addition to the actions in these two sections, the actions for spellcasting can be found on pages 299–300, and the actions for using magic items appear on page 220 of GM Core.

Delay and Ready: If you want to change when you take actions, two basic actions let you do so. Delay shifts your entire turn later in the round, and Ready lets you prepare to take one specific action when a trigger you choose is met.

Aid [reaction]

Source Core Rulebook pg. 470 4.0
Trigger An ally is about to use an action that requires a skill check or attack roll.
Requirements The ally is willing to accept your aid, and you have prepared to help (see below).
You try to help your ally with a task. To use this reaction, you must first prepare to help, usually by using an action during your turn. You must explain to the GM exactly how you’re trying to help, and they determine whether you can Aid your ally.

When you use your Aid reaction, attempt a skill check or attack roll of a type decided by the GM. The typical DC is 20, but the GM might adjust this DC for particularly hard or easy tasks. The GM can add any relevant traits to your preparatory action or to your Aid reaction depending on the situation, or even allow you to Aid checks other than skill checks and attack rolls.

Critical Success You grant your ally a +2 circumstance bonus to the triggering check. If you’re a master with the check you attempted, the bonus is +3, and if you’re legendary, it’s +4.
Success You grant your ally a +1 circumstance bonus to the triggering check.
Critical Failure Your ally takes a –1 circumstance penalty to the triggering check.

Crawl [one-action]

Move 
Source Core Rulebook pg. 470 4.0
Requirements You are prone and your Speed is at least 10 feet.
You move 5 feet by crawling and continue to stay prone.

Delay [free-action]

Source Core Rulebook pg. 470 4.0
Trigger Your turn begins.
You wait for the right moment to act. The rest of your turn doesn’t happen yet. Instead, you’re removed from the initiative order. You can return to the initiative order as a free action triggered by the end of any other creature’s turn. This permanently changes your initiative to the new position. You can’t use reactions until you return to the initiative order. If you Delay an entire round without returning to the initiative order, the actions from the Delayed turn are lost, your initiative doesn’t change, and your next turn occurs at your original position in the initiative order.

When you Delay, any persistent damage or other negative effects that normally occur at the start or end of your turn occur immediately when you use the Delay action. Any beneficial effects that would end at any point during your turn also end. The GM might determine that other effects end when you Delay as well. Essentially, you can’t Delay to avoid negative consequences that would happen on your turn or to extend beneficial effects that would end on your turn.

Drop Prone [one-action]

Move 
Source Core Rulebook pg. 470 4.0
You fall prone.

Escape [one-action]

Attack 
Source Core Rulebook pg. 470 4.0
You attempt to escape from being grabbed, immobilized, or restrained. Choose one creature, object, spell effect, hazard, or other impediment imposing any of those conditions on you. Attempt a check using your unarmed attack modifier against the DC of the effect. This is typically the Athletics DC of a creature grabbing you, the Thievery DC of a creature who tied you up, the spell DC for a spell effect, or the listed Escape DC of an object, hazard, or other impediment. You can attempt an Acrobatics or Athletics check instead of using your attack modifier if you choose (but this action still has the attack trait).

Critical Success You get free and remove the grabbed, immobilized, and restrained conditions imposed by your chosen target. You can then Stride up to 5 feet.
Success You get free and remove the grabbed, immobilized, and restrained conditions imposed by your chosen target.
Critical Failure You don’t get free, and you can’t attempt to Escape again until your next turn.

Interact [one-action]

Manipulate 
Source Core Rulebook pg. 470 4.0
You use your hand or hands to manipulate an object or the terrain. You can grab an unattended or stored object, open a door, or produce some similar effect. You might have to attempt a skill check to determine if your Interact action was successful.

Leap [one-action]

Move 
Source Core Rulebook pg. 470 4.0
You take a careful, short jump. You can Leap up to 10 feet horizontally if your Speed is at least 15 feet, or up to 15 feet horizontally if your Speed is at least 30 feet. You land in the space where your Leap ends (meaning you can typically clear a 5-foot gap, or a 10-foot gap if your Speed is 30 feet or more).

If you Leap vertically, you can move up to 3 feet vertically and 5 feet horizontally onto an elevated surface.

Jumping a greater distance requires using the Athletics skill.

Ready [two-actions]

Concentrate 
Source Core Rulebook pg. 470 4.0
You prepare to use an action that will occur outside your turn. Choose a single action or free action you can use, and designate a trigger. Your turn then ends. If the trigger you designated occurs before the start of your next turn, you can use the chosen action as a reaction (provided you still meet the requirements to use it). You can’t Ready a free action that already has a trigger.

If you have a multiple attack penalty and your readied action is an attack action, your readied attack takes the multiple attack penalty you had at the time you used Ready. This is one of the few times the multiple attack penalty applies when it’s not your turn.

Release [free-action]

Manipulate 
Source Core Rulebook pg. 470 4.0
You release something you're holding in your hand or hands. This might mean dropping an item, removing one hand from your weapon while continuing to hold it in another hand, releasing a rope suspending a chandelier, or performing a similar action. Unlike most manipulate actions, Release does not trigger reactions that can be triggered by actions with the manipulate trait (such as Attack of Opportunity).

If you want to prepare to Release something outside of your turn, use the Ready activity.

Seek [one-action]

Concentrate Secret 
Source Core Rulebook pg. 471 4.0
You scan an area for signs of creatures or objects. If you're looking for creatures, choose an area you're scanning. If precision is necessary, the GM can have you select a 30-foot cone or a 15-foot burst within line of sight. You might take a penalty if you choose an area that's far away.

If you're using Seek to search for objects (including secret doors and hazards), you search up to a 10-foot square adjacent to you. The GM might determine you need to Seek as an activity, taking more actions or even minutes or hours if you're searching a particularly cluttered area.

The GM attempts a single secret Perception check for you and compares the result to the Stealth DCs of any undetected or hidden creatures in the area or the DC to detect each object in the area (as determined by the GM or by someone Concealing the Object). A creature you detect might remain hidden, rather than becoming observed, if you're using an imprecise sense or if an effect (such as invisibility) prevents the subject from being observed.

Critical Success If you were searching for creatures, any undetected or hidden creature you critically succeeded against becomes observed by you. If you were searching for an object, you learn its location.
Success If you were searching for creatures, any undetected creature you succeeded against becomes hidden from you instead of undetected, and any hidden creature you succeeded against becomes observed by you. If you were searching for an object, you learn its location or get a clue to its whereabouts, as determined by the GM.

Sense Motive [one-action]

Concentrate Secret 
Source Core Rulebook pg. 471 4.0
You try to tell whether a creature's behavior is abnormal. Choose one creature, and assess it for odd body language, signs of nervousness, and other indicators that it might be trying to deceive someone. The GM attempts a single secret Perception check for you and compares the result to the Deception DC of the creature, the DC of a spell affecting the creature's mental state, or another appropriate DC determined by the GM. You typically can't try to Sense the Motive of the same creature again until the situation changes significantly.

Critical Success You determine the creature’s true intentions and get a solid idea of any mental magic affecting it.
Success You can tell whether the creature is behaving normally, but you don’t know its exact intentions or what magic might be affecting it.
Failure You detect what a deceptive creature wants you to believe. If they’re not being deceptive, you believe they’re behaving normally.
Critical Failure You get a false sense of the creature’s intentions.

Stand [one-action]

Move 
Source Core Rulebook pg. 471 4.0
You stand up from prone.

Step [one-action]

Move 
Source Core Rulebook pg. 471 4.0
Requirements Your Speed is at least 10 feet.
You carefully move 5 feet. Unlike most types of movement, Stepping doesn't trigger reactions, such as Attacks of Opportunity, that can be triggered by move actions or upon leaving or entering a square.

You can't Step into difficult terrain, and you can't Step using a Speed other than your land Speed.

Stride [one-action]

Move 
Source Core Rulebook pg. 471 4.0
You move up to your Speed.

Strike [one-action]

Attack 
Source Core Rulebook pg. 471 4.0
You attack with a weapon you're wielding or with an unarmed attack, targeting one creature within your reach (for a melee attack) or within range (for a ranged attack). Roll the attack roll for the weapon or unarmed attack you are using, and compare the result to the target creature's AC to determine the effect. See Attack Rolls and Damage for details on calculating your attack and damage rolls.

Critical Success As success, but you deal double damage.
Success You deal damage according to the weapon or unarmed attack, including any modifiers, bonuses, and penalties you have to damage.

Take Cover [one-action]

Source Core Rulebook pg. 471 4.0
Requirements You are benefiting from cover, are near a feature that allows you to take cover, or are prone.
You press yourself against a wall or duck behind an obstacle to take better advantage of cover. If you would have standard cover, you instead gain greater cover, which provides a +4 circumstance bonus to AC; to Reflex saves against area effects; and to Stealth checks to Hide, Sneak, or otherwise avoid detection. Otherwise, you gain the benefits of standard cover (a +2 circumstance bonus instead). This lasts until you move from your current space, use an attack action, become unconscious, or end this effect as a free action.

Specialty Basic Actions

Source Player Core pg. 418
These actions are useful under specific circumstances. The Arrest a Fall, Burrow, and Fly actions require you to have a special movement type (page 420). The climb and swim Speeds use the corresponding actions from the Athletics skill (pages 234–235).

Arrest a Fall [reaction]

Source Core Rulebook pg. 472 4.0
Trigger You fall.
Requirements You have a fly Speed.
You attempt an Acrobatics check to slow your fall. The DC is typically 15, but it might be higher due to air turbulence or other circumstances.

Success You fall gently, taking no damage from the fall.

Avert Gaze [one-action]

Source Core Rulebook pg. 472 4.0
You avert your gaze from danger. You gain a +2 circumstance bonus to saves against visual abilities that require you to look at a creature or object, such as a medusa's petrifying gaze. Your gaze remains averted until the start of your next turn.

Burrow [one-action]

Move 
Source Core Rulebook pg. 472 4.0
Requirements You have a burrow Speed.
You dig your way through dirt, sand, or a similar loose material at a rate up to your burrow Speed. You can’t burrow through rock or other substances denser than dirt unless you have an ability that allows you to do so.

Dismiss [one-action]

Concentrate 
Source Core Rulebook pg. 305 4.0
You end one spell effect or magic item effect. This must be an effect you are allowed to dismiss, as defined by the spell or item. Dismissal might end the effect entirely or might end it just for a certain target or targets, depending on the spell or item.

Fly [one-action]

Move 
Source Core Rulebook pg. 472 4.0
Requirements You have a fly Speed.
You move through the air up to your fly Speed. Moving upward (straight up or diagonally) uses the rules for moving through difficult terrain. You can move straight down 10 feet for every 5 feet of movement you spend. If you Fly to the ground, you don’t take falling damage. You can use an action to Fly 0 feet to hover in place. If you’re airborne at the end of your turn and didn’t use a Fly action this round, you fall.

Grab an Edge [reaction]

Manipulate 
Source Core Rulebook pg. 472 4.0
Trigger You fall from or past an edge or handhold.
Requirements Your hands are not tied behind your back or otherwise restrained
When you fall off or past an edge or other handhold, you can try to grab it, potentially stopping your fall. You must succeed at a Reflex save, usually at the Climb DC. If you grab the edge or handhold, you can then Climb up using Athletics.

Critical Success You grab the edge or handhold, whether or not you have a hand free, typically by using a suitable held item to catch yourself (catching a battle axe on a ledge, for example). You still take damage from the distance fallen so far, but you treat the fall as though it were 30 feet shorter.
Success If you have at least one hand free, you grab the edge or handhold, stopping your fall. You still take damage from the distance fallen so far, but you treat the fall as though it were 20 feet shorter. If you have no hands free, you continue to fall as if you had failed the check.
Critical Failure You continue to fall, and if you’ve fallen 20 feet or more before you use this reaction, you take 10 bludgeoning damage from the impact for every 20 feet fallen.

Mount [one-action]

Move 
Source Core Rulebook pg. 472 4.0
Requirements You are adjacent to a creature that is at least one size larger than you and is willing to be your mount.
You move onto the creature and ride it. If you’re already mounted, you can instead use this action to dismount, moving off the mount into a space adjacent to it.

Point Out [one-action]

Auditory Manipulate Visual 
Source Core Rulebook pg. 472 4.0
Requirements A creature is undetected by one or more of your allies but isn’t undetected by you.
You indicate a creature that you can see to one or more allies, gesturing in a direction and describing the distance verbally. That creature is hidden to your allies, rather than undetected. This works only for allies who can see you and are in a position where they could potentially detect the target. If your allies can't hear or understand you, they must succeed at a Perception check against the creature's Stealth DC or they misunderstand and believe the target is in a different location.

Raise a Shield [one-action]

Source Core Rulebook pg. 472 4.0
Requirements You are wielding a shield.
You position your shield to protect yourself. When you have Raised a Shield, you gain its listed circumstance bonus to AC. Your shield remains raised until the start of your next turn.

Sustain an Activation [one-action]

Concentrate 
Source Core Rulebook pg. 534 4.0
Requirements You have at least one magic item activation that you can sustain and you are not fatigued
Choose one magic item activation with a sustained duration you have in effect. The duration of that activation continues until the end of your next turn. Some activations may have slightly different or expanded effects if you sustain them. Sustaining an Activation for more than 10 minutes (100 rounds) ends the activation and makes you fatigued unless the item's description states a different maximum duration (such as “up to 1 minute” or “up to 1 hour”).

If your Sustain an Activation action is disrupted, the item's effect immediately ends.

Movement

Source Player Core pg. 420
Your movement and position determine how you interact with the world. Moving in exploration and downtime modes is relatively fluid. Movement in encounter mode follows additional rules explained in Tactical Movement (page 421). The rules below apply in all modes of play.

Movement Types

Source Player Core pg. 420
Creatures in Pathfinder soar through the clouds, scale sheer cliffs, and tunnel underfoot. The majority of creatures have a Speed, which is how fast they can move across the ground.

Some abilities give you different ways to move, such as through the air or underground. Each of these special movement types has its own Speed value. Many creatures have these Speeds naturally, such as a bird having a fly Speed or a fish having a swim Speed. The various types of movement are listed below. Since the Stride action can be used only with your normal Speed, moving using one of these movement types requires using a special action, and you can't Step while using one of these movement types. Since Speed by itself refers to your land Speed, rules text concerning these special movement types specifies the movement types to which it applies. Speeds can be increased or decreased with item, circumstance, and status bonuses and penalties. Penalties can't reduce your Speeds below 5 feet unless stated otherwise.

Switching from one movement type to another requires ending your action that has the first movement type and using a new action that has the second movement type. For instance, if you Climbed 10 feet to the top of a cliff, you could then Stride forward 10 feet. In some cases, the GM might rule otherwise, especially if you're moving a very short distance using one of the types of movement.

Speed

Source Player Core pg. 420
Most characters and monsters have a Speed statistic that indicates how quickly they can move across the ground. This statistic is referred to as land Speed when it's necessary to differentiate it from special Speeds.

When you use the Stride action, you move a number of feet equal to your Speed. Numerous other abilities also allow you to move, from Crawling to Leaping, and most of them are based on your Speed in some way. Whenever a rule mentions your Speed without specifying a type, it's referring to your land Speed.

Burrow Speed

Source Player Core pg. 420
A burrow Speed lets you tunnel through the ground. You can use the Burrow action (page 419) if you have a burrow Speed. Burrowing doesn’t normally leave behind a tunnel unless the ability specifically states that it does. Most creatures need to hold their breath when burrowing, and they might need tremorsense (page 433) to navigate.

Climb Speed

Source Player Core pg. 420
A climb Speed allows you to move up or down inclines and vertical surfaces. Most creatures need to succeed at Athletics checks to Climb, but if you have a climb Speed, you automatically succeed and move up to your climb Speed instead of the listed distance.

You might still have to attempt Athletics checks to Climb in hazardous conditions, to Climb extremely difficult surfaces, or to cross horizontal planes such as ceilings. You can also choose to roll an Athletics check to Climb rather than accept an automatic success in hopes of getting a critical success. Your climb Speed grants you a +4 circumstance bonus to Athletics checks to Climb.

If you have a climb Speed, you're not off-guard while you're climbing.

Fly Speed

Source Player Core pg. 420
As long as you have a fly Speed, you can use the Fly and Arrest a Fall actions (page 418). You can also attempt to Maneuver in Flight if you're trained in the Acrobatics skill.

Wind conditions can affect how you use the Fly action. In general, moving against the wind uses the same rules as moving through difficult terrain (or greater difficult terrain, if you're also flying upward), and moving with the wind allows you to move 10 feet for every 5 feet of movement you spend (not cumulative with moving straight downward). For more information on spending movement, see Tactical Movement on page 421.

Upward and downward movement are both relative to the gravity in your area; if you're in zero gravity, moving up or down is no different from moving horizontally.

Swim Speed

Source Player Core pg. 420
With a swim Speed, you can propel yourself through the water with little impediment. Instead of attempting Athletics checks to Swim, you automatically succeed and move up to your swim Speed instead of the listed distance. Moving up or down is still moving through difficult terrain.

You might still have to attempt checks to Swim in hazardous conditions or to cross turbulent water. You can also choose to roll an Athletics check to Swim rather than accept an automatic success in hopes of getting a critical success. Your swim Speed grants you a +4 circumstance bonus to Athletics checks to Swim.

Having a swim Speed doesn't necessarily mean you can breathe in water, so you might still have to hold your breath if you're underwater to avoid drowning (page 437).

Falling

Source Player Core pg. 421
If you fall more than 5 feet, when you land you take bludgeoning damage equal to half the distance you fell. Treat falls longer than 1,500 feet as though they were 1,500 feet (750 damage). If you take any damage from a fall, you land prone. You fall about 500 feet in the first round of falling and about 1,500 feet each round thereafter.

You can Grab an Edge as a reaction to reduce the damage from some falls (page 419), or Arrest a Fall if you have a fly Speed (page 418). In addition, if you fall into water, snow, or another relatively soft substance, you can treat the fall as though it were 20 feet shorter, or 30 feet shorter if you intentionally dove in. The effective reduction can't be greater than the depth (so when falling into 10-foot-deep water, you treat the fall as 10 feet shorter).

Falling on a Creature

Source Player Core pg. 421
If you land on a creature, that creature must attempt a DC 15 Reflex save. Intentionally aiming yourself to land on a creature after a long fall is almost impossible.
Critical Success The creature takes no damage.
Success The creature takes bludgeoning damage equal to one-quarter the falling damage you took.
Failure The creature takes bludgeoning damage equal to half the falling damage you took.
Critical Failure The creature takes the same amount of bludgeoning damage you took from the fall.

Falling Objects

Source Player Core pg. 421
A dropped object takes damage just like a falling creature. If the object lands on a creature, that creature can attempt a Reflex save using the same rules as for a creature falling on a creature. Hazards and spells that involve falling objects, such as a rock slide, have their own rules about how they interact with creatures and the damage they deal.

Tactical Movement

Source Player Core pg. 421
Your movement during encounter mode—and at other times where precise movement matters—depends on the actions and other abilities you use. Whether you Stride, Step, Swim, or Climb, the maximum distance you can move is based on your Speed. Certain feats or magic items can grant you other movement types, allowing you to swiftly burrow, climb, fly, or swim (page 420).

When the rules refer to a “movement cost” or “spending movement,” they are describing how many feet of your Speed you must use to move from one point to another. Normally, movement costs the number of feet you're moving. However, sometimes it's harder to move a certain distance due to difficult terrain (page 423) or other factors. In such a case, you might have to spend a different amount of movement to move from one place to another.

Grid Movement

Source Player Core pg. 421
If an encounter involves combat, it’s often a good idea to track the movement and relative position of the participants using a Pathfinder Flip-Mat or some other form of grid to display the terrain, and miniatures to represent the combatants. When a character moves on a grid, every 1-inch square of the play area is 5 feet across in the game world. Hence, a creature moving in a straight line spends 5 feet of its movement for every map square traveled. Difficult terrain, described on page 423, can make some squares cost more of your movement.

Diagonal Movement

Source Player Core pg. 421
Because moving diagonally covers more ground, you count that movement differently. The first square of diagonal movement you make in a turn counts as 5 feet, but the second counts as 10 feet, and your count thereafter alternates between the two. For example, as you move across 4 squares diagonally, you would count 5 feet, then 10, then 5, and then 10, for a total of 30 feet. You track your total diagonal movement across all your movement during your turn, but reset your count at the end of your turn. The diagram on page 423 shows an example.

3D Movement

Source Player Core pg. 421
Most movement in a game can be represented on a flat map. If creatures are flying, swimming, or otherwise moving through three-dimensional space, see the advice on page 437 under Special Battles.

Size, Space, and Reach

Source Player Core pg. 421
Creatures and objects of different sizes occupy different amounts of space. The sizes and the spaces they each take up on a grid are listed in the Size and Reach table (see below). The table also lists the typical reach for creatures of each size, for both tall creatures (most bipeds) and long creatures (most quadrupeds). See page 426 for more about reach.

The Space entry lists how many feet on a side a creature's space is, so a Large creature fills a 10-foot-by- 10-foot space, or 4 squares on the grid. (If you need to measure in three dimensions, their space is also 10 feet high.) Sometimes part of a creature extends beyond its space, such as if a giant octopus is grabbing you with its tentacles. In that case, the GM will usually allow attacking the extended portion, even if you can't reach the main creature.

Table 9-1: Size and Reach

SizeSpaceReach (Tall)Reach (Long)
TinyLess than 5 feet0 feet0 feet
Small5 feet5 feet5 feet
Medium5 feet5 feet5 feet
Large10 feet10 feet5 feet
Huge15 feet15 feet10 feet
Gargantuan20 feet or more20 feet15 feet

A Small or larger creature or object takes up at least 1 square on a grid, and creatures of these sizes can't usually share spaces except in situations like a character riding a mount.

Multiple Tiny creatures can occupy the same square. At least four can fit in a single square, though the GM might determine that even more can fit. Tiny creatures can share a space occupied by a larger creature as well. If a Tiny creature's reach is 0 feet, it must share a space with a creature in order to attack it.

Moving Through a Creature’s Space

Source Player Core pg. 422
You can move through the space of a willing creature. If you want to move through an unwilling creature’s space, you can Tumble Through it (see Acrobatics on page 233). You can’t end your turn in a square occupied by another creature, though you can end a move action in its square provided that you immediately use another move action to leave that square. If two creatures end up in the same square by accident, the GM determines which one is forced out of the square (or whether one falls prone).

Prone and Incapacitated Creatures

Source Player Core pg. 422
You can share a space with a prone creature if that creature is willing, unconscious, or dead and if it is your size or smaller. The GM might allow you to climb atop the corpse or unconscious body of a larger creature in some situations. A prone creature can’t stand up while someone else occupies its space, but it can Crawl to a space where it’s able to stand, or it can attempt to Shove the other creature out of the way.

Creatures of Different Sizes

Source Player Core pg. 422
In most cases, you can move through the space of a creature three sizes larger than you or larger. This means a Medium creature can move through the space of a Gargantuan creature and a Small creature can move through the space of a Huge or Gargantuan creature. Likewise, a bigger creature can move through the space of a creature three sizes smaller than itself or smaller. You still can't end your movement in a space occupied by a creature.

Tiny creatures are an exception, just like with sharing a space. They can move through creatures' spaces and can even end their movement there.

Similarly, other creatures can move through and end their movement in a Tiny creature's space.

Objects

Source Player Core pg. 422
Because objects aren’t as mobile as creatures are, they’re more likely to fill a space. This means you can’t always move through their spaces like you might move through a space occupied by a creature. You might be able to occupy the same square as a statue of your size, but not a wide column. The GM determines whether you can move into an object’s square normally, whether special rules apply, or if you are unable to move into the square at all.

Forced Movement

Source Player Core pg. 422
When an effect forces you to move, or if you start falling, the distance you move is defined by the effect that moved you, not by your Speed. Forced movement doesn't trigger reactions that are triggered by movement. Some common causes of forced movement include the Reposition and Shove actions of Athletics. In the rare cases where it's unclear whether your movement is voluntary or forced, the GM makes the determination.

If forced movement would move you into a space you can't occupy—because objects are in the way or because you lack the movement type needed to reach it, for example—you stop moving in the last space you can occupy.

Usually the creature or effect forcing the movement chooses the path the victim takes. If you're pushed or pulled, you can usually be moved through hazardous terrain, pushed off a ledge, or the like. Abilities that reposition you in some other way can't put you in such dangerous places unless they specify otherwise. In all cases, the GM makes the final call if there's doubt on where forced movement can move a creature.

Some abilities allow a creature to move while carrying another along with it. This is forced movement for the carried creature. Unless noted otherwise, they both move on the same path while this happens—the carrying creature can't drag its victim through dangers while avoiding them itself, for example.

Terrain

Source Player Core pg. 423
Several types of terrain can complicate your movement by slowing you down, damaging you, or endangering you. Navigating these types of terrain can be challenging, but it can also let you get an advantage over your foes.

Difficult Terrain

Source Player Core pg. 423
Difficult terrain is any terrain that impedes your movement, ranging from particularly rough or unstable surfaces to thick ground cover and countless other impediments. Moving into a square of difficult terrain (or moving 5 feet into or within an area of difficult terrain, if you're not using a grid) costs an extra 5 feet of movement. Moving into a square of greater difficult terrain instead costs 10 additional feet of movement. This additional cost is not increased further when moving diagonally. You can't Step into difficult terrain.

Movement you make while jumping ignores the terrain you're jumping over. Some abilities (such as flight or being incorporeal) allow you to avoid the movement reduction from some types of difficult terrain.

Ignore Difficult Terrain

Source Player Core pg. 423
Certain abilities let you ignore difficult terrain. If you can ignore difficult terrain, you can also move through greater difficult terrain at the extra movement cost difficult terrain normally imposes. An ability doesn’t let you entirely ignore greater difficult terrain unless the ability specifies otherwise.

Hazardous Terrain

Source Player Core pg. 423
Hazardous terrain damages you whenever you move through it. An acid pool and a pit of burning embers are both examples of hazardous terrain. The amount and type of damage depend on the specific hazardous terrain.

Narrow Surfaces

Source Player Core pg. 423
A narrow surface is so precariously thin that you need to Balance (see Acrobatics on page 233) or risk falling. Even on a success, you are off-guard on a narrow surface. Each time you are hit by an attack or fail a save on a narrow surface, you must succeed at a Reflex save (with the same DC as the Acrobatics check to Balance) or fall.

Uneven Ground

Source Player Core pg. 423
Uneven ground is an area unsteady enough that you need to Balance (see Acrobatics on page 233) or risk falling prone and possibly injuring yourself, depending on the specifics of the uneven ground. You are off-guard on uneven ground. Each time you are hit by an attack or fail a save on uneven ground, you must succeed at a Reflex save (with the same DC as the Acrobatics check to Balance) or fall prone.

Inclines

Source Player Core pg. 423
An incline is an area so steep that you need to Climb using the Athletics skill in order to progress upward. You’re off-guard when Climbing an incline.

Cover

Source Player Core pg. 424
When you're behind an obstacle that could block weapons, guard you against explosions, and make you harder to detect, you're behind cover. Standard cover gives you a +2 circumstance bonus to AC, to Reflex saves against area effects, and to Stealth checks to Hide, Sneak, or otherwise avoid detection. You can increase this to greater cover using the Take Cover basic action (page 418), increasing the circumstance bonus to +4. If cover is especially light, typically when it's provided by a creature, you have lesser cover, which grants a +1 circumstance bonus to AC. A creature with standard cover or greater cover can attempt to use Stealth to Hide, but lesser cover isn't sufficient.

Cover

Type of CoverBonusCan Hide
Lesser+1 to ACNo
Standard+2 to AC, Reflex, StealthYes
Greater+4 to AC, Reflex, StealthYes

Cover is relative, so you might simultaneously have cover against one creature and not another. Cover applies only if your path to the target is partially blocked. If a creature is entirely behind a wall or the like, you don't have line of effect (page 426) and typically can't target it at all.

Usually, the GM can quickly decide whether your target has cover. If you're uncertain or need to be more precise, draw a line from the center of your space to the center of the target's space. If that line passes through any terrain or object that would block the effect, the target has standard cover (or greater cover if the obstruction is extreme or the target has Taken Cover). If the line passes through a creature instead, the target has lesser cover. When measuring cover against an area effect, draw the line from the effect's point of origin to the center of the creature's space. See the diagram for examples.

Cover and Large Creatures

Source Player Core pg. 424
If a creature between you and a target is two or more sizes larger than both you and your target, that creature’s space blocks the effect enough to provide standard cover instead of lesser cover. The GM might determine that a creature doesn’t gain cover from terrain that it’s significantly larger than. For example, a Huge dragon probably wouldn’t receive any benefit from being behind a 1-foot-wide pillar.

Special Circumstances

Source Player Core pg. 424
Your GM might allow you to overcome your target’s cover in some situations. If you’re right next to an arrow slit, you can shoot without penalty, but you have greater cover against someone shooting back at you from far away. Your GM might let you reduce or negate cover by leaning around a corner to shoot or the like. This usually takes an action to set up, and the GM might measure cover from an edge or corner of your space instead of your center.

3D Flanking

Source Player Core pg. 425
Though battle grids are often two-dimensional, the game world isn't! Sometimes you might need to visualize a creature's space as a cube for flanking. For instance, if Valeros is underneath a flying sphinx while Lini is flying above the sphinx, they might be flanking it even if they're piled in an odd stack on your battle grid. And if Valeros were mounted on a horse, he might be able to measure from farther off the ground than normal.

In these cases, it's usually best to have the GM make the call on who's flanking rather than trying to do meticulous measurements in three dimensions.

Flanking

Source Player Core pg. 425
When you and an ally are flanking a foe, it has a harder time defending against you. A creature is off-guard (taking a –2 circumstance penalty to AC) to melee attacks from creatures that are flanking it.

To flank a foe, you and your ally must be on opposite sides of the creature. A line drawn between the center of your space and the center of your ally's space must pass through opposite sides or opposite corners of the foe's space. Additionally, both you and the ally have to be able to act, you must be wielding melee weapons or be able to make an unarmed attack, you can't be under any effects that prevent you from attacking, and you must both have the enemy within reach. If you are wielding a reach weapon, you use your reach with that weapon for this purpose.

Effects

Source Player Core pg. 426
Anything you do in the game has an effect. Many of these outcomes are easy to adjudicate during the game. If you tell the GM that you draw your sword, no check is needed. Other times, the specific effect requires more detailed rules governing how your choice is resolved.

Many spells, magic items, and feats create specific effects, and your character will be subject to effects caused by monsters, hazards, the environment, and other characters.

Effects sometimes require checks, but not always. Casting a fly spell on yourself creates an effect that allows you to soar through the air, but casting the spell does not require a check. Conversely, using the Intimidate skill to Demoralize a foe does require a check, and your result on that check determines the effect's outcome.

Duration

Source Player Core pg. 426
Most effects are discrete, creating an instantaneous effect when you let the GM know what actions you are going to use. Firing a bow, moving to a new space, or taking something out of your pack all resolve instantly. Other effects instead last for a certain duration. Once the duration has elapsed, the effect ends. The rules generally use the following conventions for durations, though spells have some special durations detailed on pages 302.

For an effect that lasts a number of rounds, the remaining duration decreases by 1 at the start of each turn of the creature that created the effect. Detrimental effects often last “until the end of the target's next turn” or “through” a number of their turns (such as “through the target's next 3 turns”), which means that the effect's duration decreases at the end of the creature's turn, rather than the start.

Instead of lasting a fixed number of rounds, a duration might end only when certain conditions are met (or cease to be true). If so, the effects last until those conditions are met.

Some effects can be ended early with the Dismiss action (page 419). An effect with the sustained duration lasts until the end of your next turn, but it can be extended as described in the Sustain action (page 419).

Range and Reach

Source Player Core pg. 426
Abilities that generate an effect typically work within a specified range or a reach. Most spells and abilities list a range—the maximum distance from the creature or object creating the effect in which the effect can occur.

Ranged and thrown weapons have a range increment. Attacks with such weapons work normally up to that range. Attacks against targets beyond that range take a –2 penalty, which worsens by 2 for every additional multiple of that range, to a maximum of a –10 penalty after five additional range increments. Attacks beyond this range are not possible. For example, using a shortbow, your attacks take no penalty against a target up to 60 feet away, a –2 penalty if a target is over 60 and up to 120 feet away, a –4 if they're over 120 and up to 180 feet away, and so on, up to a maximum of 360 feet.

Reach is how far you can physically reach with your body or a weapon. Melee Strikes rely on reach. Your reach is typically 5 feet, but weapons with the reach trait can extend this. Larger creatures can have greater reach; for instance, an ogre has a 10-foot reach. Unlike with measuring most distances, 10-foot reach can reach 2 squares diagonally. Reach greater than 10 feet is measured normally: 20-foot reach can reach 3 squares diagonally, 30-foot reach can reach 4, and so on.

Targets

Source Player Core pg. 426
Some effects require you to choose specific targets. Targeting can be difficult or impossible if your chosen creature is undetected by you, if the creature doesn't match restrictions on who you can target, or if some other ability prevents it from being targeted.

Some effects require a target to be willing. Only you can decide whether your PC is willing, and the GM decides whether an NPC is willing. Even if you or your character don't know what the effect is, such as if your character is unconscious, you still decide if you're willing.

Some effects target or require an ally, or otherwise refer to an ally. This must be someone on your side, often another PC, but it might be a bystander you are trying to protect. You don't count as your own ally. If it isn't clear, the GM decides who counts as an ally or an enemy.

Areas

Source Player Core pg. 426
Some effects occupy an area of a specified shape and size. An area effect always has a point of origin and extends out from that point. There are four types of areas: emanations, bursts, cones, and lines. See page 428 for details.

Line of Effect

Source Player Core pg. 426
When creating an effect, you usually need an unblocked path to the target of a spell, the origin point of an effect's area, or the place where you create something with a spell or other ability. This is called a line of effect. You have line of effect unless a creature is entirely behind a solid physical barrier. Visibility doesn't matter for line of effect, nor do portcullises and other barriers that aren't totally solid. Usually a 1-foot-square gap is enough to maintain a line of effect, though the GM makes the final call.

In an area effect, creatures or targets must have line of effect to the point of origin to be affected. If there's no line of effect between the origin of the area and the target, the effect doesn't apply to that target. For example, if there's a solid wall between the origin of a fireball and a creature that's within the burst radius, the wall blocks the effect—that creature is unaffected by the fireball and doesn't need to attempt a save against it. Likewise, any ongoing effects created by an ability with an area cease to affect anyone who moves outside of the line of effect.

Line of Sight

Source Player Core pg. 427
Some effects require you to have line of sight to your target. As long as you can precisely sense the area (as described in Perception on page 433) and it is not blocked by a solid barrier (as described in Cover on page 424), you have line of sight. An area of darkness prevents line of sight if you don’t have darkvision, but portcullises and other obstacles that aren’t totally solid do not. Usually a 1-foot-square gap is enough to maintain line of sight, though the GM makes the final call.

Area

Source Player Core pg. 428
An area always has a point of origin and extends out from that point. There are four types of areas: emanations, bursts, cones, and lines.

When you're playing in encounter mode and using a grid, areas are measured in the same way as movement (page 420), but areas' distances are never affected by difficult terrain. Standard or greater cover can apply against areas, but not lesser cover. You can use the diagrams on page 429 as common reference templates for areas, rather than measuring squares each time. Many area effects describe only the effects on creatures in the area. The GM determines any effects to the environment and unattended objects.

Burst

Source Player Core pg. 428
A burst effect issues forth in all directions from a single corner of a square within the range of the effect, spreading in all directions to a specified radius. For instance, when you cast fireball, it detonates at the corner of a square within 500 feet of you and creates a 20-foot burst, meaning it extends out 20 feet in every direction from the corner of the square you chose, affecting each creature whose space (or even one square of its space) is within the burst.

Cone

Source Player Core pg. 428
A cone shoots out from you in a quarter circle on the grid. When you aim a cone, the first square of that cone must share an edge with your space if you're aiming orthogonally, or it must touch a corner of your space if you're aiming diagonally. If you're Large or larger, the first square can run along the edge of any square of your space. You can't aim a cone so that it overlaps your space. The cone extends out for a number of feet, widening as it goes, as shown in the Areas diagram. For instance, if you cast the breathe fire spell, you create a cone of flames that originates at the edge of one square of your space and affects a quarter-circle area 15 feet on each edge.

If you make a cone originate elsewhere, use these same rules, with the first square of the cone using an edge or corner of that creature or object's space instead of your own.

Emanation

Source Player Core pg. 428
An emanation issues forth from each side of your space, extending out to a specified number of feet in all directions. For instance, the bless spell’s emanation radiates 15 or more feet outward from the caster. Because the sides of a creature’s space are the starting point for the emanation, an emanation from a Large or larger creature affects a greater overall area than that of a Medium or smaller creature. Unless the text states otherwise, the creature creating an emanation effect chooses whether the creature at its center is affected.

Line

Source Player Core pg. 428
A line shoots forth from you, following a straight path in a direction of your choosing. The line affects each creature whose space it overlaps. Unless a line effect says otherwise, it is 5 feet wide. For example, the lightning bolt spell’s area is a 60-foot line that’s 5 feet wide.

Afflictions

Source Player Core pg. 430
Diseases and poisons are types of afflictions, as are curses and radiation. An affliction can infect a creature for a long time, progressing through different and often increasingly debilitating stages.

Format

Source Player Core pg. 430
Whether appearing in a spell, as an item, or within a creature’s stat block, afflictions appear in the following format.

Name and Traits

Source Player Core pg. 430
The affliction’s name is given first, followed by its traits in parentheses—including the trait for the type of affliction (curse, disease, poison, and so forth). If the affliction needs to have a level specified, it follows the parentheses, followed by any unusual details, such as restrictions on removing the conditions imposed by an affliction. If no level is listed, the affliction matches the level of the creature, hazard, or item causing the affliction.

Saving Throw

Source Player Core pg. 430
When you're first exposed to the affliction, you must attempt a saving throw against it. This first attempt to stave off the affliction is called the initial save. An affliction usually requires a Fortitude save, but the exact save and its DC are listed after the name and type of affliction. Spells that can cause an affliction typically use the caster's spell DC.

On a successful initial saving throw, you are unaffected by that exposure to the affliction. You don't need to attempt further saving throws against it unless you are exposed to the affliction again.

If you fail the initial saving throw, you advance to stage 1 of the affliction and are subjected to the listed effect. On a critical failure, after its onset period (if applicable), you advance to stage 2 of the affliction and are subjected to that effect instead.

Onset

Source Player Core pg. 430
Some afflictions have onset times. For these afflictions, once you fail your initial save, you don’t gain the effects for the first stage of the affliction until the onset time has elapsed. If this entry is absent, you gain the effects for the first stage (or the second stage on a critical failure) immediately upon failing the initial saving throw.

Maximum Duration

Source Player Core pg. 430
If an affliction lasts only a limited amount of time, it lists a maximum duration. Once this duration passes, the affliction ends. Otherwise, it lasts until you succeed at enough saves to recover, as described in Stages below.

Stages

Source Player Core pg. 430
An affliction typically has multiple stages, each of which lists an effect followed by an interval in parentheses. When you reach a given stage of an affliction, you are subjected to the effects listed for that stage.

At the end of a stage's listed interval, you must attempt a new saving throw. On a success, you reduce the stage by 1; on a critical success, you reduce the stage by 2. You are then subjected to the effects of the new stage. If the affliction's stage is ever reduced below stage 1, the affliction ends and you don't need to attempt further saves unless you're exposed to the affliction again.

On a failure, the stage increases by 1; on a critical failure, the stage increases by 2. You are then subjected to the effects listed for the new stage. If a failure or critical failure would increase the stage beyond the highest listed stage, the affliction instead repeats the effects of the highest stage.

Damage and Conditions

Source Player Core pg. 430
Any damage listed for a stage happens immediately when you reach that stage. Conditions affect you when you reach the stage and last for their normal duration. For instance, if you were drained for an affliction with a maximum duration of 5 minutes, you remain drained after the affliction ends, as normal for the drained condition. A condition that automatically changes its value or ends under certain circumstances, like frightened, still does so. Any condition that doesn’t have a default duration, such as clumsy or paralyzed, lasts as long as you’re at that stage unless noted otherwise, as do any penalties or any other effect of the stage that doesn’t list a duration.

Multiple Exposures

Source Player Core pg. 430
Multiple exposures to the same curse or disease currently affecting you have no effect. For a poison, however, failing the initial saving throw against a new exposure increases the stage by 1 (or by 2 if you critically fail) without affecting the maximum duration. This is true even if you’re within the poison’s onset period, though it doesn’t change the onset length. If the poison does not have an onset time or it’s already elapsed, you are immediately subject to the effects of the new stage.

Virulent Afflictions

Source Player Core pg. 431
Afflictions with the virulent trait are harder to remove. You must succeed at two consecutive saves to reduce a virulent affliction’s stage by 1. A critical success reduces a virulent affliction’s stage by only 1 instead of by 2.

Removing Afflictions

Source Player Core pg. 431
Apart from waiting them out, afflictions can be removed through certain uses of the skills and spells. The Treat Disease and Treat Poison uses of Medicine are commonly used to treat those afflictions.

The cleanse affliction spell is also available to most spellcasters. Spells that counteract conditions at the source, such as sound body, can also be effective against diseases and poisons that cause those conditions.

Curses are trickier, requiring solutions that specifically mention them, such as a 4th-rank cleanse affliction or the Break Curse skill feat.

Perception and Detection

Source Player Core pg. 432
Your Perception measures your ability to notice things, search for what’s hidden, and tell whether something about a situation is suspicious.
Perception is frequently used for rolling initiative in an encounter, and for the Seek action. See page 404 for the procedure for rolling a Perception check.

Light

Source Player Core pg. 432
There are three levels of light: bright light, dim light, and darkness. The rules in this book assume that all creatures are in bright light unless otherwise noted. A source of light lists the radius in which it sheds bright light, and it sheds dim light to double that radius.

Bright Light

Source Player Core pg. 432
In bright light, such as sunlight, creatures and objects can be observed clearly by anyone with average vision or better.

Dim Light

Source Player Core pg. 432
Areas in shadow or lit by weak light sources are in dim light. Creatures and objects in dim light have the concealed condition, unless the seeker has darkvision or low-light vision (see page 433), or a precise sense other than vision.

Darkness

Source Player Core pg. 432
A creature or object within darkness is hidden or undetected unless the seeker has darkvision or a precise sense other than vision. A creature without darkvision or another means of perceiving in darkness has the blinded condition while in darkness, though it might be able to see illuminated areas beyond the darkness. If a creature can see into an illuminated area, it can observe creatures within that illuminated area normally. After being in darkness, sudden exposure to bright light might make you dazzled for a short time, as determined by the GM.

Senses

Source Player Core pg. 432
The ways a creature can use Perception depend on what senses it has. The primary concepts you need to know for understanding senses are precise senses, imprecise senses, and the three states of detection a target can be in: observed, hidden, or undetected. Vision, hearing, and scent are three prominent senses, but each has a different degree of acuity.

Precise Senses

Source Player Core pg. 433
Average vision is a precise sense—a sense that can be used to perceive the world in nuanced detail. The only way to target a creature without having drawbacks is to use a precise sense. You can usually detect a creature automatically with a precise sense unless that creature is hiding or obscured by the environment, in which case you can use the Seek basic action to better detect the creature.

Imprecise Senses

Source Player Core pg. 433
Average hearing is an imprecise sense—it can’t detect the full range of detail that a precise sense can. You can usually sense a creature automatically with an imprecise sense, but it has the hidden condition instead of the observed condition. It might be undetected by you if it’s using Stealth or is in an environment that distorts the sense, such as a noisy room in the case of hearing. In those cases, you have to use the Seek basic action to detect the creature. At best, an imprecise sense can be used to make an undetected creature (or one you didn’t even know was there) merely hidden—it can’t make the creature observed.

Vague Senses

Source Player Core pg. 433
A character also has many vague senses—ones that can alert you that something is there but aren't useful for zeroing in on it to determine exactly what it is. The most useful of these for a typical character is the sense of smell. At best, a vague sense can be used to detect the presence of an unnoticed creature, making it undetected. Even then, the vague sense isn't sufficient to make the creature hidden or observed.

When one creature might detect another, the GM almost always uses the most precise sense available.

Pathfinder's rules assume that a given creature has vision as its only precise sense and hearing as its only imprecise sense. Some characters and creatures, however, have precise or imprecise senses that don't match this assumption. For instance, a character with poor vision might treat that sense as imprecise, an animal with the scent ability can use its sense of smell as an imprecise sense, and a creature with echolocation or a similar ability can use hearing as a precise sense. Such senses are often given special names and appear as “echolocation (precise),” “scent (imprecise) 30 feet,” etc.

Special Senses

Source Player Core pg. 433
While a human might have a difficult time making creatures out in dim light, an elf can see those creatures just fine. And though elves have no problem seeing on a moonlit night, their vision can’t penetrate complete darkness, whereas a dwarf’s can. Special senses allow a creature to ignore or reduce the effects of the undetected, hidden, or concealed conditions (described on page 434) when it comes to situations that foil average vision.

Darkvision and Greater Darkvision

Source Player Core pg. 433
A creature with darkvision or greater darkvision can see perfectly well in areas of darkness and dim light, though such vision is in black and white only. Some forms of magical darkness, such as a 4th-rank darkness spell, block normal darkvision. A creature with greater darkvision, however, can see through even these forms of magical darkness.

Low-Light Vision

Source Player Core pg. 433
A creature with low-light vision can see in dim light as though it were bright light, so it ignores the concealed condition due to dim light.

Scent

Source Player Core pg. 433
Scent involves sensing creatures or objects by smell, and is usually a vague sense. The range is listed in the ability, and it functions only if the creature or object being detected emits an aroma. If a creature emits a heavy aroma or is upwind, the GM can double or even triple the range of scent abilities used to detect that creature, and the GM can reduce the range if a creature is downwind.

Tremorsense

Source Player Core pg. 433
Tremorsense allows a creature to feel the vibrations through a solid surface caused by movement. It is usually an imprecise sense with a limited range (listed in the ability). Tremorsense functions only if the detecting creature is on the same surface as the subject, and only if the subject is moving along (or burrowing through) the surface.

Detecting Creatures

Source Player Core pg. 434
Three conditions measure the degree to which you can sense a creature: observed, hidden, and undetected. However, the concealed and invisible conditions can partially mask a creature, and the unnoticed condition indicates you have no idea a creature is around. You can find these conditions in the Conditions Appendix on pages 442–447.

With the exception of invisible, these conditions are relative to the viewer—it's possible for a creature to be observed to you but hidden from your ally. Most of these rules apply to objects as well as creatures.

Typically, the GM tracks how well creatures detect each other, since neither party has perfect information. For example, you might think a creature is in the last place you sensed it, but it was able to Sneak away. Or you might think a creature can't see you in the dark, but it has darkvision.

You can attempt to avoid detection by using the Stealth skill (page 244) to Avoid Notice, Hide, or Sneak, or by using Deception to Create a Diversion (page 237).

Observed

Source Player Core pg. 434
In most circumstances, you can sense creatures without difficulty and target them normally. Creatures in this state are observed. Observing requires a precise sense, which for most creatures means sight. If you can’t observe the creature, it’s either hidden, undetected, or unnoticed, and you’ll need to factor in the targeting restrictions. Even if a creature is observed, it might still be concealed.

Hidden

Source Player Core pg. 434
A creature that's hidden is only barely perceptible. You know what space it occupies, but little else. Perhaps the creature just moved behind cover and successfully used the Hide action. Your target might be behind a waterfall, where you can see some movement but can't determine an exact location. Maybe you've been blinded or the creature is invisible, but you used the Seek basic action to determine its general location based on hearing alone. Regardless of the specifics, you're off-guard to a hidden creature.

When targeting a hidden creature, before you roll to determine your effect, you must attempt a DC 11 flat check. If you fail, you don't affect the creature, though the actions you used are still expended—as well as any spell slots, costs, and other resources. You remain off-guard to the creature, whether you successfully target it or not.

Undetected

Source Player Core pg. 434
If a creature is undetected, you don't know what space it occupies, you're off-guard to it, and you can't easily target it. Using the Seek basic action can help you find an undetected creature, usually making it hidden from you instead of undetected. If a creature is undetected, that doesn't necessarily mean you're unaware of its presence—you might suspect an undetected creature is in the room with you, even though you're unable to find its space. The unnoticed condition covers creatures you're unaware of.

Targeting an undetected creature is difficult. If you suspect there's a creature around, you can pick a square and attempt an attack. This works like targeting a hidden creature, but the flat check and attack roll are both rolled in secret by the GM. The GM won't tell you why you missed—whether it was due to failing the flat check, rolling an insufficient attack roll, or choosing the wrong square. The GM might allow you to try targeting an undetected creature with some spells or other abilities in a similar fashion. Undetected creatures are subject to area effects normally.

For instance, suppose an enemy elf wizard cast invisibility and then Sneaked away. You suspect that with the elf's Speed of 30 feet, they probably moved 15 feet toward an open door. You move up and attack a space 15 feet from where the elf started and directly on the path to the door. The GM secretly rolls an attack roll and flat check, but they know that you were not quite correct—the elf was actually in the adjacent space! The GM tells you that you missed, so you decide to make your next attack on the adjacent space, just in case. This time, it's the right space, and the GM's secret attack roll and flat check both succeed, so you hit!

Unnoticed

Source Player Core pg. 434
If you have no idea a creature is even present, that creature is unnoticed by you. A creature that is undetected might also be unnoticed. This condition usually matters for abilities that can be used only against targets totally unaware of your presence.

Concealed

Source Player Core pg. 434
A concealed creature is in mist, within dim light, or amid something else that obscures sight but isn’t a physical barrier. When you target a creature that’s concealed from you, you must attempt a DC 5 flat check before you roll to determine your effect. If you fail, you don’t affect the target. The concealed condition doesn’t change which of the main categories of detection apply. A creature in a light fog bank is still observed even though it’s concealed.

Invisible

Source Player Core pg. 434
A creature with the invisible condition (by way of an invisibility spell, for example) is automatically undetected to any creatures relying on sight as their only precise sense. Precise senses other than sight ignore the invisible condition. You can Seek (page 417) to attempt to figure out an invisible creature's location, making it only hidden from you. This lasts until the invisible creature successfully uses Sneak to become undetected again. If you're already observing a creature when it becomes invisible, it starts out hidden, since you know where it was, though it can then Sneak to become undetected.

Other effects might partially foil invisibility. For instance, if you were tracking an invisible creature's footprints through the snow, the footprints would make it hidden. Throwing a net over an invisible creature would make it observed but concealed for as long as the net is on it.

Encounter Mode

Source Player Core pg. 435
When every individual action counts, you enter the encounter mode of play. In this mode, time is divided into rounds, each of which is 6 seconds of time in the game world. Every round, each participant takes a turn in an established order. During your turn, you can use actions, and depending on the details of the encounter, you might have the opportunity to use reactions and free actions on your own turn and on others’ turns.

Structure

Source Player Core pg. 435
An encounter is played out in a series of rounds, during which the player characters, adversaries, and other participants in the encounter act in sequence. You roll initiative to determine this order at the start of the encounter and then play through rounds until a conclusion is reached and the encounter ends. The rules in this section assume a combat encounter—a battle—but the general structure can apply to any kind of encounter. Other types of encounters, like social encounters, might use longer rounds or have other modifications to the basic structure.

Step 1: Roll Initiative

Source Player Core pg. 435
When the GM calls for it, you'll roll initiative to determine your place in the initiative order, which is the sequence in which the encounter's participants will take their turns. Rolling initiative marks the start of an encounter. More often than not, you'll roll initiative when you enter a battle.

Typically, you'll roll a Perception check to determine your initiative—the more aware you are of your surroundings, the more quickly you can respond. Sometimes, though, the GM might call on you to roll some other type of check. For instance, if you were Avoiding Notice during exploration (page 438), you'd roll a Stealth check. A social encounter could call for a Deception or Diplomacy check. In most cases, you can still use Perception if you prefer.

The GM rolls initiative for anyone other than the player characters in the encounter. If these include a number of identical creatures, the GM could roll once for the group as a whole and have them take their turns within the group in any order. However, this can make battles less predictable and more dangerous, so the GM might want to roll initiative for some or all creatures individually unless it's too much of a burden.

Unlike a check, where the result is compared to a DC, the results of initiative rolls are ranked. This ranking sets the order in which the encounter's participants act—the initiative order. The character with the highest result goes first. The second highest follows, and so on until whoever had the lowest result takes their turn last.

If your result is tied with an enemy's result, the enemy goes first. If your result is tied with another PC's, you can decide between yourselves who goes first when you reach that place in the initiative order. After that, your places in the initiative order usually don't change during the encounter. (But see the Delay basic action on page 416.)

Step 2: Play a Round

Source Player Core pg. 435
A round begins when the participant with the highest initiative roll result starts their turn, and it ends when the one with the lowest initiative ends their turn. The process of taking a turn is detailed below. Creatures might also act outside their turns with reactions and free actions.

Step 3: Begin the Next Round

Source Player Core pg. 435
Once everyone in the encounter has taken a turn, the round is over and the next one begins. Don’t roll initiative again; the new round proceeds in the same order as the previous one, repeating the cycle until the encounter ends.

Step 4: End the Encounter

Source Player Core pg. 435
When your foes are defeated, some sort of truce is reached, or some other event or circumstance ends the combat, the encounter is over. You and the other participants no longer follow the initiative order, and a more free-form style of play resumes, with the game typically moving into exploration mode. Sometimes, at the end of an encounter, the GM will award Experience Points to the party or you’ll find treasure to divvy up.

Turns

Source Player Core pg. 435
When it’s your turn to act, you can use single actions ( [one-action] ), short activities ( [two-actions] and [three-actions] ), reactions ( [reaction] ), and free actions ( [free-action] ). When you’re finished, your turn ends and the character next in the initiative order begins their turn. Sometimes it’s important to note when during your turn something happens, so a turn is divided into three steps.

Step 1: Start Your Turn

Source Player Core pg. 435
Many things happen automatically at the start of your turn—it's a common point for tracking the passage of time for effects that last multiple rounds. At the start of each of your turns, take these steps in any order you choose:
  • If you created an effect lasting for a certain number of rounds, reduce the number of rounds remaining by 1. The effect ends if the duration is reduced to 0. For example, if you cast a spell that lasts 3 rounds on yourself during your first turn of a fight, it would affect you during that turn, decrease to 2 rounds of duration at the start of your second turn, decrease to 1 round of duration at the start of your third turn, and expire at the start of your fourth turn.
  • You can use 1 free action or reaction with a trigger of “Your turn begins” or something similar.
  • If you're dying, roll a recovery check (page 411).
  • Do anything else that is specified to happen at the start of your turn, such as regaining Hit Points from fast healing or regeneration.
The last step of starting your turn is always the same.
  • Regain your 3 actions and 1 reaction. If you haven't spent your reaction from your last turn, you lose it—you can't “save” actions or reactions from one turn to use during the next turn. Some abilities or conditions (such as quickened, slowed, and stunned) can change how many actions you regain and whether you regain your reaction. (Details on gaining and losing actions are on page 446.)

Step 2: Act

Source Player Core pg. 436
You can use actions in any order you wish during your turn, but you have to complete one action or activity before beginning another; for example, you can't use a single action in the middle of performing a 2-action activity. What actions you can use often depend on your class features, skills, feats, and items, but there are default actions anyone can use, described in Basic Actions on page 416. Some effects might prevent you from acting. If you can't act, you can't use any actions, including reactions and free actions.

If you begin a 2-action or 3-action activity on your turn, you must be able to complete it on your turn. You can't, for example, begin to High Jump using your final action on one turn and then complete it as your first action on your next turn.

Once you have spent all 3 of your actions, your turn ends (as described in Step 3) and the next creature's turn begins. You can choose to end your turn early, losing all remaining actions (but not your reaction).

Step 3: End Your Turn

Source Player Core pg. 436
Once you've done all the things you want to do with the actions you have available, you reach the end of your turn. Take the following steps in any order you choose. Play then proceeds to the next creature in the initiative order.
  • End any effects that last until the end of your turn. For example, spells with a sustained duration end at the end of your turn unless you used the Sustain a Spell action during your turn to extend them. Some effects caused by enemies might also last through a certain number of your turns, and you decrease the remaining duration by 1 during this step, ending the effect if its duration is reduced to 0.
  • If you have a persistent damage condition, you take the damage at this point. After you take the damage, you can attempt the flat check to end the persistent damage. You then attempt any saving throws for ongoing afflictions. Many other conditions change at the end of your turn, such as the frightened condition decreasing in severity. These take place after you've taken any persistent damage, attempted flat checks to end the persistent damage, and attempted saves against any afflictions.
  • You can use 1 free action or reaction with a trigger of “Your turn ends” or something similar.
  • Resolve anything else specified to happen at the end of your turn.

Activities in Encounters

Source Player Core pg. 436
Activities that take longer than a turn can’t normally be performed during an encounter. Spells with a casting time of 1 minute or more are a common example, as are several skill actions. When you commit to an activity during your turn in an encounter, you commit to spending all of the actions it requires. If the activity gets interrupted partway through, you lose all of the actions you would have spent on that activity. Activities are described on page 414.

Reactions in Encounters

Source Player Core pg. 436
Your reactions let you respond immediately to what’s happening around you. The GM determines whether you can use reactions before your first turn begins, depending on the situation in which the encounter happens. Once your first turn begins, you gain your actions and reaction. You gain 1 reaction per round. You can use a reaction on anyone’s turn (including your own), but only when its trigger occurs. If you don’t use your reaction, you lose it at the start of your next turn, though you typically then gain a reaction at the start of that turn.

Special Battles

Source Player Core pg. 437

Mounted Combat

Source Player Core pg. 437
You can ride some creatures into combat. As noted in the Mount specialty basic action (page 419), your mount needs to be willing and at least one size larger than you. Your mount acts on your initiative. You must use the Command an Animal action (page 242) to get your mount to spend its actions. If you don't, the animal wastes its actions. If you have the Ride general feat, you succeed automatically when you Command an Animal that's your mount.

For example, if you are mounted on a horse and you make three attacks, your horse would remain stationary since you didn't command it. If you instead spent your first action to Command an Animal and succeeded, you could get your mount to Stride. You could spend your next action to attack or to command the horse to attack, but not both.

Mounted Attacks

Source Player Core pg. 437
You and your mount fight as a unit. Consequently, you share a multiple attack penalty. For example, if you Strike and then Command an Animal to have your mount Strike, your mount's attack takes a –5 multiple attack penalty.

You occupy every square of your mount's space for the purpose of making attacks. If you were a Medium creature on a Large mount, you could attack a creature on one side of your mount, then attack on the opposite side. On a Medium or smaller mount, use the normal reach of an attack. On a Large or Huge mount, you can attack any square adjacent to the mount if you have 5- or 10-foot reach, or any square within 10 feet of the mount (including diagonally) if you have 15-foot reach. Use the adjusted reach for determining flanking and other rules that depend on reach.

Mounted Defenses

Source Player Core pg. 437
Attackers can target either you or your mount. An area effect affects both of you as long as you're both in the area. You are in an attacker's reach or range if any square of your mount is within reach or range. Because your mount is larger than you and you share its space, you have lesser cover against attacks targeting you when you're mounted if the mount would be in the way (as determined by the GM).

Because you can't move your body as freely while you're riding a mount, you take a –2 circumstance penalty to Reflex saves while mounted. Additionally, the only move action you can use is the Mount action to dismount.

Aerial Combat

Source Player Core pg. 437
Many monsters can fly, and PCs can use spells and items to gain the ability to fly. Flying creatures have to use the Fly action (page 419) to move through the air. Performing an especially tricky maneuver might require using Acrobatics to Maneuver in Flight. Creatures might fall from the sky, using the falling rules found on page 421. At the GM’s discretion, some ground-based actions might not work in the air. For instance, a flying creature couldn’t Leap.

Aquatic Combat

Source Player Core pg. 437
Use these rules for battles in water or underwater:
  • You're off-guard unless you have a swim Speed.
  • You gain resistance 5 to acid and fire.
  • You take a –2 circumstance penalty to melee slashing or bludgeoning attacks that pass through water.
  • Ranged attacks that deal bludgeoning or slashing damage automatically miss if the attacker or target is underwater, and piercing ranged attacks made by an underwater creature or against an underwater target have their range increments halved.
  • You can't cast fire spells or use actions with the fire trait underwater. As normal for how traits work, any part of the effect that's unrelated to fire still works. For example, an attack with a flaming battleaxe could still deal its physical damage, just not its fire damage.
  • At the GM's discretion, some ground-based actions might not work underwater or while floating.

Drowning and Suffocating

Source Player Core pg. 437
You can hold your breath for a number of rounds equal to 5 + your Constitution modifier. Reduce your remaining air by 1 round at the end of each of your turns, or by 2 if you attacked or cast any spells that turn. You also lose 1 round worth of air each time you are critically hit or critically fail a save against a damaging effect. If you speak (including Casting a Spell) you lose all remaining air.

When you run out of air, you fall unconscious and start suffocating. You can't recover from being unconscious and must attempt a DC 20 Fortitude save at the end of each of your turns. On a failure, you take 1d10 damage, and on a critical failure, you die. On each check after the first, the DC increases by 5 and the damage by 1d10; these increases are cumulative. Once your access to air is restored, you stop suffocating and are no longer unconscious (unless you're at 0 Hit Points).

Exploration Mode

Source Player Core pg. 438
While encounters use rounds for combat, exploration is more free form. The GM determines the flow of time, as you could be traveling by horseback across craggy highlands, negotiating with merchants, or delving in a dungeon in search of danger and treasure. Exploration lacks the immediate danger of encounter mode, but it offers its own challenges.

Much of exploration mode involves movement and roleplaying. You might be traveling from one town to another, chatting with a couple of merchants in an outpost along the way, or maybe having a terse conversation with the watchful city guards at your destination. Instead of measuring your rate of movement in 5-foot squares every round, you measure it in feet or miles per minute, hour, or day, using your travel speed. Rather than deciding on each action every turn, you'll engage in an exploration activity, and you'll typically spend some time every day resting and making your daily preparations.

Travel Speed

Source Player Core pg. 438
Depending on how the GM tracks movement, you move in feet or miles based on your character’s Speed with the relevant movement type. Typical rates are on the table below.

Travel Speed

SpeedFeet per MinuteMiles per HourMiles per Day
10 feet10018
15 feet1501-1/212
20 feet200216
25 feet2502-1/220
30 feet300324
35 feet3503-1/228
40 feet400432
50 feet500540
60 feet600648

The rates in the table assume traveling over flat and clear terrain at a determined pace, but one that’s not exhausting. Moving through difficult terrain halves the listed movement rate. Greater difficult terrain reduces the distance traveled to one-third the listed amount. If the travel requires a skill check to accomplish, such as mountain climbing or swimming, the GM might call for a check once per hour using the result and the table above to determine your progress.

Exploration Activities

Source Player Core pg. 438
While you're traveling and exploring, tell the GM what you'd generally like to do along the way. If you do nothing more than make steady progress toward your goal, you move at the full travel speeds given in the table.

When you want to do something other than simply travel, you describe what you are attempting to do. It isn't necessary to go into extreme detail, such as “Using my dagger, I nudge the door so I can check for devious traps.” Instead, “I'm searching the area for hazards” is sufficient. The GM finds the best exploration activity to match your description and describes the effects of that activity. Some exploration activities limit how fast you can travel and be effective.

These are most common exploration activities.

Avoid Notice

Exploration 
Source Core Rulebook pg. 479 4.0
You attempt a Stealth check to avoid notice while traveling at half speed. If you have the Swift Sneak feat, you can move at full Speed rather than half, but you still can’t use another exploration activity while you do so. If you have the Legendary Sneak feat, you can move at full Speed and use a second exploration activity. If you’re Avoiding Notice at the start of an encounter, you usually roll a Stealth check instead of a Perception check both to determine your initiative and to see if the enemies notice you (based on their Perception DCs, as normal for Sneak, regardless of their initiative check results).

Defend

Exploration 
Source Core Rulebook pg. 479 4.0
You move at half your travel speed with your shield raised. If combat breaks out, you gain the benefits of Raising a Shield before your first turn begins.

Raise a Shield [one-action]

Source Core Rulebook pg. 472 4.0
Requirements You are wielding a shield.
You position your shield to protect yourself. When you have Raised a Shield, you gain its listed circumstance bonus to AC. Your shield remains raised until the start of your next turn.

Detect Magic

Concentrate Exploration 
Source Core Rulebook pg. 479 4.0
You cast detect magic at regular intervals. You move at half your travel speed or slower. You have no chance of accidentally overlooking a magic aura at a travel speed up to 300 feet per minute, but must be traveling no more than 150 feet per minute to detect magic auras before the party moves into them.

Follow the Expert

Auditory Concentrate Exploration Visual 
Source Core Rulebook pg. 479 4.0
Choose an ally attempting a recurring skill check while exploring, such as climbing, or performing a different exploration tactic that requires a skill check (like Avoiding Notice). The ally must be at least an expert in that skill and must be willing to provide assistance. While Following the Expert, you match their tactic or attempt similar skill checks. Thanks to your ally’s assistance, you can add your level as a proficiency bonus to the associated skill check, even if you’re untrained. Additionally, you gain a circumstance bonus to your skill check based on your ally’s proficiency (+2 for expert, +3 for master, and +4 for legendary).

Hustle

Exploration Move 
Source Core Rulebook pg. 480 4.0
You strain yourself to move at double your travel speed. You can Hustle only for a number of minutes equal to your Constitution modifier × 10 (minimum 10 minutes). If you are in a group that is Hustling, use the lowest Constitution modifier among everyone to determine how fast the group can Hustle together.

Investigate

Concentrate Exploration 
Source Core Rulebook pg. 480 4.0
You seek out information about your surroundings while traveling at half speed. You use Recall Knowledge as a secret check to discover clues among the various things you can see and engage with as you journey along. You can use any skill that has a Recall Knowledge action while Investigating, but the GM determines whether the skill is relevant to the clues you could find.

Repeat a Spell

Concentrate Exploration 
Source Core Rulebook pg. 480 4.0
You repeatedly cast the same spell while moving at half speed. Typically, this spell is a cantrip that you want to have in effect in the event a combat breaks out, and it must be one you can cast in 2 actions or fewer. In order to prevent fatigue due to repeated casting, you’ll likely use this activity only when something out of the ordinary occurs.

You can instead use this activity to continue Sustaining a Spell or Activation with a sustained duration. Most such spells or item effects can be sustained for 10 minutes, though some specify they can be sustained for a different duration.

Scout

Concentrate Exploration 
Source Core Rulebook pg. 480 4.0
You scout ahead and behind the group to watch danger, moving at half speed. At the start of the next encounter, every creature in your party gains a +1 circumstance bonus to their initiative rolls.

Search

Concentrate Exploration 
Source Core Rulebook pg. 480 4.0
You Seek meticulously for hidden doors, concealed hazards, and so on. You can usually make an educated guess as to which locations are best to check and move at half speed, but if you want to be thorough and guarantee you checked everything, you need to travel at a Speed of no more than 300 feet per minute, or 150 feet per minute to ensure you check everything before you walk into it. You can always move more slowly while Searching to cover the area more thoroughly, and the Expeditious Search feat increases these maximum Speeds. If you come across a secret door, item, or hazard while Searching, the GM will attempt a free secret check to Seek to see if you notice the hidden object or hazard. In locations with many objects to search, you have to stop and spend significantly longer to search thoroughly.

Sustain an Activation [one-action]

Concentrate 
Source Core Rulebook pg. 534 4.0
Requirements You have at least one magic item activation that you can sustain and you are not fatigued
Choose one magic item activation with a sustained duration you have in effect. The duration of that activation continues until the end of your next turn. Some activations may have slightly different or expanded effects if you sustain them. Sustaining an Activation for more than 10 minutes (100 rounds) ends the activation and makes you fatigued unless the item's description states a different maximum duration (such as “up to 1 minute” or “up to 1 hour”).

If your Sustain an Activation action is disrupted, the item's effect immediately ends.

Rest and Daily Preparations

Source Player Core pg. 439
You're at your best when you take time to rest and prepare. Once every 24 hours, you can take a period of rest (typically 8 hours), during which you heal naturally, regaining Hit Points equal to your Constitution modifier (minimum 1) times your level, and you might recover from or improve certain conditions. Sleeping in armor results in poor rest that leaves you fatigued. If you go more than 16 hours without resting, you become fatigued (you can't recover from this fatigue until you rest at least 8 continuous hours).

After you rest, you make your daily preparations, which takes around 1 hour. You can prepare only if you've rested, and only once per day. During preparations:
  • Spellcasters regain spell slots, and prepared spellcasters choose spells to have available that day.
  • Focus Points, abilities that refresh during preparations, and abilities that can be used only a certain number of times per day, including magic item uses, are reset.
  • You don armor and equip weapons and other gear.
  • You invest up to 10 worn magic items to gain their benefits for the day (as explained in GM Core).

Downtime Mode

Source Player Core pg. 440
Downtime mode is played day-by-day rather than minute-by-minute or scene-by-scene. Usually, this mode of play occurs when you are in the safety of a settlement, maybe recovering from your adventures or studying an artifact you found.

Downtime gives you time to rest fully, engage in crafting or a professional endeavor, learn new spells, retrain feats, or just have fun. You can sell items acquired during your adventures, buy new goods, and perform other activities as determined by your feats, your skills, and the settlement where you are spending the downtime.

Earning Income

Source Player Core pg. 440
The Earn Income skill action (page 228) allows you to make money using a wide variety of skills. You can get creative with the skills you attempt to use, working with the GM on the details. Some skills might be much harder to earn money with than others. Crafting, Lore, and Performance are the most reliable. Jobs in a fantasy world tend not to be particularly stable, so you might need to look for new tasks on a fairly regular basis.

The GM determines the levels of jobs you can find, as noted in the Earn Income activity. It's often in your best interest to determine what types of jobs are available for a small variety of skills, so you can take on the most lucrative or interesting option.

Long-Term Rest

Source Player Core pg. 440
You can spend an entire day and night resting during downtime to recover Hit Points equal to your Constitution modifier (minimum 1) multiplied by double your level.

Retraining

Source Player Core pg. 440
Retraining offers a way to alter your character choices, which is helpful when you want to take your character in a new direction or change decisions that didn't meet your expectations. You can retrain feats, skills, and some selectable class features. You can't retrain your ancestry, heritage, background, class, or attribute modifiers. You can't perform other downtime activities while retraining.

Retraining usually requires you to spend time learning from a teacher, whether that entails physical training, studying at a library, or falling into shared magical trances.

Your GM determines whether you can get proper training or whether something can be retrained at all. In some cases, you'll have to pay your instructor. Some abilities can be difficult or impossible to retrain (for instance, witch can retrain their patron only in extraordinary circumstances).

When retraining, you generally can't make choices you couldn't make when you selected the original option. For instance, you can't replace a skill feat you chose at 2nd level for a 4th-level one, or for one that requires prerequisites you didn't meet at the time you took the original feat. If you don't remember whether you met the prerequisites at the time, ask your GM to make the call. If you cease to meet the prerequisites for an ability due to retraining, you can't use that ability. You might need to retrain several abilities in sequence in order to get all the abilities you want.

Feats

Source Player Core pg. 441
You can spend a week of downtime retraining to swap out one of your feats. Remove the old feat and replace it with another of the same type. For example, you could swap a skill feat for another skill feat, but not for a wizard feat.

Skills

Source Player Core pg. 441
You can spend a week of downtime retraining to swap out one of your skill increases. Reduce your proficiency rank in the skill losing its increase by one step and increase your proficiency rank in another skill by one step. The new proficiency rank has to be equal to or lower than the proficiency rank you traded away. For instance, if your bard is a master in Performance and Stealth, and an expert in Occultism, you could reduce the character's proficiency in Stealth to expert and become a master in Occultism, but you couldn't reassign that skill increase to become legendary in Performance. Keep track of your level when you reassign skill increases; the level at which your skill proficiencies changed can influence your ability to retrain feats with skill prerequisites.

You can also spend a week to retrain an initial trained skill you selected during character creation.

Class Features

Source Player Core pg. 441
You can change a class feature that required a choice, making a different choice instead. Some, like changing a spell in your spell repertoire, take a week. The GM will tell you how long it takes to retrain larger choices like a druid order or a wizard school—it is always at least a month.

Shopping and Crafting

Source Player Core pg. 441
If you're at a location with shops that buy or sell magic items, you can buy, sell, or trade. Ask the GM what types of shopping options are available to you—it can vary greatly depending where you're spending your downtime!

Because of the complexities of finding shops that are looking for items you want to sell or that offer ones you want to buy, dedicated shopping takes 1 day of downtime. It might take longer if you're selling a large number of goods, expensive items that require a wealthy buyer, or items that aren't in high demand.

The Price of an item indicates the full cost to buy it. You can sell an item for half its Price. The GM might adjust these once in a while due to supply and demand or the particular merchants you're dealing with.

Item Crafting

Source Player Core pg. 441
You can spend downtime to use the Craft skill activity (page 236), making new items out of raw materials. Crafting can be an excellent way to refine the gear the party uses, including upgrading items and preparing ones you’re likely to need on an upcoming quest.

Other Activities

Work with your GM if there are other ways you want to spend downtime. You might acquire property, manage a business, become part of a guild, curry favor in a large city, take command of an army, take on an apprentice, start a family, or minister to a flock of the faithful. Though there are efficient options for making money or adjusting your character, it’s often better to seek out fun and interesting activities that can open up new opportunities for character building, adventures, or relationships.

Goals

Source Player Core pg. 441
You can help guide the course of the campaign by setting long-term goals that take multiple periods of downtime to complete. Talk them through with the GM and the rest of the group. Consider alliances you want to develop further or changes you want to see in the game world.

Conditions Appendix

Source Player Core pg. 442
While adventuring, characters (and sometimes their belongings) are affected by abilities and effects that apply conditions. For example, a spell or magic item might turn you invisible or cause you to be gripped by fear. Conditions change your state of being in some way, and they represent everything from the attitude other creatures have toward you and how they interact with you to what happens when a creature drains your blood or life essence.

Conditions are persistent. Whenever you're affected by a condition, its effects last until the condition's stated duration ends, the condition is removed, or terms dictated in the condition itself cause it to end.

Condition Values

Source Player Core pg. 442
Some conditions have a number after the condition, called a condition value. This value conveys the severity of a condition, and such conditions often give you a bonus or penalty equal to their value. These values can often be reduced by skills, spells, or simply waiting. If a condition value is ever reduced to 0, the condition ends.

Overriding Conditions

Source Player Core pg. 442
Some conditions override others. This is always specified in the entry for the overriding condition. When this happens, all effects of the overridden condition are suppressed until the overriding condition ends. The overridden condition’s duration continues to elapse, and it might run out while suppressed.
