What is the Guts setting rule? I keep looking around in core and even other books and cant find it. Its used in the containment setting guide.
Sorry for the confusion! Guts is a setting rule from Deadlands but it's a pretty easy one:
You add a new Skill to the game called Guts. Instead of making a Spirit check to oppose Fear, you make a Guts check. That's all it is. Hope that helps!
