With some characters at least, often you'll pray in a cool IC way when you're about to do something cool, or have just done something cool.

I mean, I hesitate to encourage that because it can be taken way too far, and god knows I don't want to see 913 prays a minute because everyone thinks they're Rambo, but done in moderation and well it really highlights a character's roleplay and calls attention to some of their better moments.
