Chapter 9: Playing the Game / General Rules / Actions / Actions with Triggers

Limitation on Triggers

Source Core Rulebook pg. 462
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.
