Amulet of Zealotry

An amulet of zealotry is an obsidian disk marked with the symbol of a god or other eminently powerful entity and hanging from a metal chain.

The amulet functions as a holy symbol and arcane focus for any spellcaster that draws their power from the entity it is dedicated to.

The amulet has 2 charges. As an action, the person wearing the amulet can use one of its charges to try and dominate someone else, the target must be within 30ft and visible, and can't be an undead or a construct. The target must make a DC17 Wisdom saving throw, on a failure, you control the target completely until the end of their next turn. 

The amulet regains all charges daily at dawn.
