Immediate Action

An immediate action is any action, usually performed in response to another character or event, which takes place outside the order of initiative on a turn other than their own. Immediate actions can be either standard or free, and immediate standard actions use up one of the character’s standard actions for that round. As such, a character can only take an immediate standard action if she would have standard actions remaining on her next turn (unless her next turn would be on a new round).
