Amulet of Protection from Good

This iron charm is affixed to a black leather cord.  The disc-like amulet is shaped like a beastly maw with licking flames emitting from the mouth.  The wearer is under the constant effects of a variant form of protection from good and evil spell.  Good-aligned creatures attack the bearer at a disadvantage and the wearer is immune to charm, fright, or possession by them.

Notes: Immunity: Charmed, Immunity: Frightened, Disadvantage: Attack Rolls Against You, Buff, Jewelry
