You have a knack for activating magic items even if you don't know how they work.

Prerequisite(s): Cha 15, Use Magic Device 3 ranks

Benefit: When you attempt to activate a magic item blindly with the Use Magic Device skill, you get a +2 bonus on your check and you only suffer a mishap if you fail by 15 or more. If you have seen the item activated or used before, you get an additional +4 bonus on the check. Once you have activated an item yourself, you learn how it works and no longer need to activate it blindly.

Normal: You suffer a mishap if you fail by 10 or more and you must continue to activate an item blindly even after having activated it before.
