Chapter 1: Introduction

Playing the Game

Source Player Core pg. 8 2.0
In a Pathfinder game, three modes of play determine the pacing of each scene in the story. Most of your character's time is spent in exploration, uncovering mysteries, solving problems, and interacting with other characters. The Age of Lost Omens abounds with danger, however, and characters often find themselves in an encounter, fighting savage beasts and terrifying monsters. Finally, time moves quickly when the characters enjoy downtime, a respite from the world's troubles and a chance to rest and train for future expeditions. Throughout an adventure, gameplay moves between these three modes many times, as needed for the story. The more you play the game, the more you'll see that each mode has its own play style, but moving from mode to mode has few hard boundaries.

During the game, your character will face situations where the outcome is uncertain. A character might need to climb a sheer cliff, track down a wounded chimera, or sneak past a sleeping dragon, all of which are dangerous tasks with a price for failure. In such cases, the acting character (or characters) will be asked to attempt a check to determine whether or not they succeed. A check is usually made by rolling a single 20-sided die (a d20) and adding a number based on the relevant attribute. In such cases, rolling high is always good.

Once a check is rolled, the GM compares the result to a target number called the difficulty class (DC) to determine the outcome. If the result of the check is equal to or greater than the DC, the check is successful. If it is less, the check is a failure. Beating the DC by 10 or more is referred to as a critical success, which usually grants an especially positive outcome. Similarly, failing the check by 10 or more is a critical failure (sometimes called a fumble). This sometimes results in additional negative effects. You also often score a critical success by rolling a 20 on the die when attempting a check (before adding anything). Likewise, rolling a 1 on the die when attempting a check often results in a critical failure. Note that not all checks have a special effect on a critical success or critical failure and such results should be treated just like an ordinary success or failure instead.

For example, in pursuit of the wounded chimera, your character might find the path blocked by a fast-moving river. You decide to swim across, but the GM declares this a dangerous task and asks you to roll an Athletics skill check (since swimming is covered by the Athletics skill). On your character sheet, you see that your character has a +8 modifier for such checks. Rolling the d20, you get an 18, for a total of 26. The GM compares this to the DC (which was 16) and finds that you got a critical success (since the result exceeded the DC by 10). Your character swims quickly across the river and continues the pursuit, drenched but unharmed. Had you gotten a result less than 26 but equal to or greater than 16, your character would have made it halfway across the river. Had your result been less than 16, your character might have been swept downriver or, worse, been pulled under the current and begun to drown!

Checks like this are the heart of the game and are rolled all the time, in every mode of play, to determine the outcome of tasks. While the roll of the die is critical, the statistic you add to the roll (called a modifier) often makes the difference between success and failure. Every character is made up of many such statistics governing what the character is good at, each consisting of a relevant attribute modifier plus a proficiency bonus, and sometimes modified further by other factors, such as bonuses or penalties from gear, spells, feats, magic items, and other special circumstances.

Proficiency is a simple way of assessing your character's general level of training and aptitude for a given task. It is broken into five different ranks: untrained, trained, expert, master, and legendary. Each rank grants a different proficiency bonus. If you're untrained at a statistic, your proficiency bonus is +0—you must rely solely on the raw potential represented by your attribute modifier. If your proficiency rank for a statistic is trained, expert, master, and legendary, your bonus equals your character's level plus another number based on the rank (2, 4, 6, and 8, respectively). Proficiency ranks are part of almost every statistic in the game.

Exploration

Most of the time, your character will explore the world, interact with characters, travel from place to place, and overcome challenges. This is called exploration. Gameplay is relatively free-form during exploration, with players responding to the narrative whenever they have an idea of what to do next. Leaving town via horseback, following the trail of a marauding orc tribe, avoiding the tribe's scouts, and convincing a local hunter to help in an upcoming fight are all examples of things that might occur during exploration.

Throughout this mode of play, the GM asks the players what their characters are doing as they explore. This is important in case a conflict arises. If combat breaks out, the tasks the PCs undertook while exploring might give them an edge or otherwise inform how the combat begins.

Encounters

Source Player Core pg. 9 2.0
In the course of your adventures, there will be times when a simple skill check is not enough to resolve a challenge—when fearsome monsters stand in your character's way and the only choice is to do battle. In Pathfinder, this is called an encounter. Encounters usually involve combat, but they can also be used in situations where timing is critical, such as during a chase or when dodging hazards.

While exploration is handled in a free-form manner, encounters are more structured. The players and GM roll initiative to determine who acts in what order. The encounter occurs over a number of rounds, each of which is equal to about 6 seconds of time in the world of the game. During a round, each participant takes a turn. When it's your turn to act, you can use up to three actions. Most simple things, such as drawing a weapon, moving a short distance, opening a door, or swinging a sword, use a single action to perform. There are also activities that use more than a single action to perform; these are often special abilities from your character's class and feats. One common activity in the game is casting a spell, which usually uses two actions.

Free actions, such as dropping an object, don't count toward the three actions you can take on your turn. Finally, each character can use up to one reaction during a round. This special type of action can be used even when it's not your turn, but only in response to certain events, and only if you have an ability that allows it. Rogues, for example, can select a feat that lets them use their reaction to dodge an incoming attack.

Attacking another creature is one of the most common actions in combat, and is done by using the Strike action. This requires an attack roll—a kind of check made against the Armor Class (AC) of the creature you're attacking. Strikes can be made using weapons, spells, or even parts of a creature's body, like a fist, claw, or tail. You add a modifier to this roll based on your proficiency rank with the type of attack you're using, your attributes, and any other bonuses or penalties based on the situation. The target's AC is calculated using their proficiency rank in the armor they're wearing and their Dexterity modifier. An attack deals damage if it hits, and rolling a critical success results in the attack dealing double damage!

You can use more than one Strike action on your turn, but each additional attack after the first becomes less accurate. This is reflected by a multiple attack penalty that starts at –5 on the second attack, but increases to –10 on the third. There are many ways to reduce this penalty, and it resets at the end of your turn.

If your character finds themself the target of a magical lightning bolt or the victim of a venomous snake bite, you will be called on to attempt a saving throw, representing your character's ability to avoid danger or otherwise withstand an assault to their mind or body. A saving throw is a check attempted against the DC of the spell or special ability targeting your character. There are three types of saving throws, and a character's proficiency in each says a great deal about what they can endure. A Fortitude saving throw is used when your character's health or vitality is under attack, such as from poison or disease. A Reflex saving throw is called for when your character must dodge away from danger, usually something that affects a large area, such as the scorching blast of a fireball spell. Finally, a Will saving throw is often your defense against spells and effects that target your character's mind, such as a charm or confusion spell. For all saving throws, a success lessens the harmful effect, and scoring a critical success usually means your character escapes unscathed.

Attacks, spells, hazards, and special abilities frequently either deal damage to a character or impose one or more conditions—and sometimes both. Damage is subtracted from a creature's Hit Points (HP)—a measure of health—and when a creature is reduced to 0 HP, it falls unconscious and may die! A combat encounter typically lasts until one side has been defeated, and while this can mean retreat or surrender, it most often happens because one side is dead or dying. Conditions can hinder a creature for a time, limiting the actions they can use and applying penalties to future checks. Some conditions are even permanent, requiring a character to seek out powerful magic to undo their effects.

Downtime

Source Player Core pg. 9 2.0
PCs don’t have to spend every waking moment adventuring. They might also recover from wounds, plan future conquests, or pursue a trade. In Pathfinder, this is called downtime, and it allows time to pass quickly while characters work on long-term tasks or objectives. Most characters can practice a trade in downtime, earning a few coins, but those with the right skills can also spend time crafting, creating new gear or even magic items. Characters can also use downtime to retrain, replacing one character choice with another to reflect their evolving priorities. They might also research a problem, learn new spells, or even run a business or kingdom!
