Amulet of the Frostmaiden

This amulet belonged to one of Auril's devoted followers. Given to her as a gift from the Frostmaiden, it signified her trust and belief in Auril. If someone puts it on and is not a follower of the Frostmaiden, they have to succeed on a Wisdom saving throw (DC 13) or they will slowly lose their sanity from hearing Auril's voice in their head. Once it is put on they cannot take it off. If it is taken off the wearer must make a Constitution saving throw (DC 14) or take 1d10 psychic damage. There is a way to communicate with the Frostmaidem through the amulet, but they must find someone proficient in cursed magic to discover how. It gives resistance to cold damage. 

Notes: Resistance: Cold, Damage: Psychic
