Chapter 7: Spells

Durations

Source Core Rulebook pg. 304
The duration of a spell is how long the spell effect lasts. Spells that last for more than an instant have a Duration entry. A spell might last until the start or end of a turn, for some number of rounds, for minutes, or even longer. If a spell’s duration is given in rounds, the number of rounds remaining decreases by 1 at the start of each of the spellcaster’s turns, ending when the duration reaches 0.

Some spells have effects that remain even after the spell’s magic is gone. Any ongoing effect that isn’t part of the spell’s duration entry isn’t considered magical. For instance, a spell that creates a loud sound and has no duration might deafen someone for a time, even permanently. This deafness couldn’t be counteracted because it is not itself magical (though it might be cured by other magic, such as restore senses).

If a spell’s caster dies or is incapacitated during the spell’s duration, the spell remains in effect till its duration ends. You might need to keep track of the caster’s initiative after they stopped being able to act to monitor spell durations.

Sustaining Spells

Source Core Rulebook pg. 304
If the spell’s duration is “sustained,” it lasts until the end of your next turn unless you use a Sustain a Spell action on that turn to extend the duration of that spell.

Sustain a Spell Single Action

Concentrate
Source Core Rulebook pg. 304
Requirements You have at least one spell active with a sustained duration, and you are not fatigued.
Choose one spell with a sustained duration you have in effect. The duration of that spell continues until the end of your next turn. Some spells might have slightly different or expanded effects if you sustain them. Sustaining a Spell for more than 10 minutes (100 rounds) ends the spell and makes you fatigued unless the spell lists a different maximum duration (such as “sustained up to 1 minute” or “sustained up to 1 hour”).

If your Sustain a Spell action is disrupted, the spell immediately ends.

Long Durations

Source Core Rulebook pg. 305
If a spell’s duration says it lasts until your next daily preparations, on the next day you can refrain from preparing a new spell in that spell’s slot. (If you are a spontaneous caster, you can instead expend a spell slot during your preparations.) Doing so extends the spell’s duration until your next daily preparations. This effectively Sustains the Spell over a long period of time. If you prepare a new spell in the slot (or don’t expend a spell slot), the spell ends. You can’t do this if the spell didn’t come from one of your spell slots. If you are dead or otherwise incapacitated at the 24-hour mark after the time you Cast the Spell or the last time you extended its duration, the spell ends. Spells with an unlimited duration last until counteracted or Dismissed. You don’t need to keep a spell slot open for these spells.

Dismissing

Source Core Rulebook pg. 305
Some spells can be dismissed, ending the duration early. This requires the caster or target to use the Dismiss action.

Dismiss Single Action

Concentrate
Source Core Rulebook pg. 305
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.
