The bone charm

This disgusting fetish necklace is made from the skull of a small mammal and what looks to be human knuckle bones. It was found on the corpse of a giant kappa alpha male.

By grasping it in one hand and spending a point of willpower the wearer can increase their armor rating by one for a single scene. Giving their skin a shell like appearance. This can be done once per day.

Wearing it however prevents 10s from exploding on all social rolls made among civilized society.
