Intolerance
You dislike or even hate something. It could be an object, kind of person, action, or anything you or your fiendish storyteller can come up with. Whatever it is, when you are confronted with the object of your intolerance, you must roll self control at a difficulty of 6, modified by the intensity of the event at the Storyteller's discretion. Failure indicates that you frenzy, with the subject of your hatred being the target of the Beast's wrath. This difficulty could be particularly high if you are intolerant of something that normally provokes the beast anyway, such as being insulted.
