I can't get it to work with ANY stat, though. Vitality, WarriorLore, AirResistance (all stats I've seen used), nothing works right. The statuses activate, so I know OnCharacterStatus works with sneaking, but can't seem to make it depend on a stat. I just tried a talent, and I can get it to depend on, say Stench or Backstab. Pretty excited that I can buff talents in this way, so I guess I'll start with that, but really want to buff the sneak skill as well. Maybe I can apply some kind of status with sneak in a roundabout way.
