Amulet of the Barrow

This amulet is shaped from a thin plate of polished bone, delicately inscribed with a knotwork pattern. It smells faintly of freshly turned earth.

Undead with a Challenge Rating of 2 or less ignore you as though you were also undead, unless commanded to attack you. If you initiate hostilities with an undead creature, the amulet loses this property until the end of your next long rest.
