Today, WotC posted a web enhancement for Fortress of the Yuan-Ti. In the web enhancement, it says players should be awarded action points for performing certain tasks in each encounter. At one point, the text specifies that the action point is good for a specific future encounter. I wish I knew what the action point does once spent! Anyway, I like the idea of action points as rewards for clever and brave acts. I can see some newer DMs maybe having trouble deciding when to reward these action points, especially in homebrew campaigns where you don't have the adventure author telling you when to award them. Can anyone figure out a specific criteria that would help DMs know when it is a good time to award action points?
