Amulet Of The Restless

As an action, you can speak a command word and call forth all the captured spirits to protect you. They swarm around you to a distance of 15 feet for 10 minutes. When you use this ability, you can designate any number of creatures you can see to be unaffected by it. When an affected creature enters the area for the first time on a turn or starts its turn there, it must make a DC 15 Wisdom saving throw. On a failed save, the creature takes 1d8 necrotic damage for each captured soul. On a successful save, the creature takes half as much damage.
Additionally, if a creature dies inside the area, its soul is dragged into the locket of captured souls.

Notes: Damage: Necrotic, The amulet hangs on a simple silver chain, belying its otherworldly nature. It appears as a arrow with the center having a large black stone that anyone would be able to tell is not from this world, Combat, Necklace
