Amulet of Antimagis

This amulet, shaped like a mouth, can absorb anything before it. The wearer can use an action to absorb. If the target being absorbed is a sentient creature, then it must make a DC 20 Charisma saving throw else it be consumed by the mouth of Antimagis. Creatures consumed in such a way are killed and cannot be brought back to life, short of a deity’s wish. While attuned to the amulet the wearer gains the key abilities of creatures that the wearer has consumed.
