Pinch Bugs
Gnosis 3
Pinch bugs are fetishes that appear to be some kind of larger insect - ladybugs, bumblebees or mantises, for example - crafted from clay and often painted garish colors. A werewolf can stick one of these little bugs to an item he wants to protect from casual snooping, activating the fetish as it is attached. When anyone but the werewolf tries to open or disturb the item in question, the pinch bug comes to life and "stings" the offender. This is nonlethal, but it's exceedingly painful, like the worst wasp sting imaginable. If the offender has some compelling reason to remain silent, he must make a Willpower roll, difficulty 8, to avoid screeching or hurling some kind of expletive at the top of his lungs.
