Amulet of Fear

The Amulet of Fear summons the power, chaos, and madness of the Plane of Pandemonium to protect its wearer.  The amulet has 6 charges and regains 1d4+2 charges at dusk.  Whenever the wearer is hit by an attack they can use their reaction to expend a charge from the amulet and attempt to frighten the attacking creature.  The attacking creature must succeed a Wisdom saving throw (DC 15) or direct the attack at another creature and becomes frightened of the wearer until the end of the target's next turn.  If the target can not attack any other creature on its turn, it instead loses the attack.

Each time the amulet is used on the same creature, the spell save DC decreases by 2.  If a creature saves against the amulet, it is immune to its effects for 24 hours.
