StuntBonus is given out for fanciful, heroic, and exciting player descriptions:

* A level one stunt has artistic description; it feels like it could fit in an action movie.

* A level two stunt has artistic description and involves the scenery; it adds props or set pieces to the game.

* A level three stunt provokes exclamations of awe from the rest of the table.

I've been thinking about some of the objections I've heard to this, and here goes:

* Sneaky People Won't Get Stunts:  the purpose of the stunt mechanic is to make the game more fun for everybody.  Sitting around while the GM and the sneaky person run off for two hours isn't nearly as much fun as hearing about the exploits of the sneaky person.  So if you want to keep things secret from the players, we'll go off in a corner.  If you want to keep  things secret from the characters, we'll do it at the table and people who metagame will receive harsh but unfair responses.

* You Can Only Stunt in Combat: it's true that action movies focus on combat, acrobatics, and physical exertion.  Non-combat or social characters should have plenty of opportunity to stunt.  Descriptions of cinematic effects are what are necessary, not damage rolls.  Glances, obscure T'Skrang dinner utensils, and similar flourishes will generate stunt bonuses.
