Amulet of soul capture

An amulet with a large ruby gem at the center and an intricate silver frame.

As long as the amulet is empty, a creature that is slain while holding it has their soul trapped within until the gem is broken (35 AC, spells have no effect) or the enchantment is dispelled (DC 25). When the soul is released from the amulet, it is sent to the appropriate plane.

If a soul is locked within the amulet, any creature that touches it must succeed on a Wisdom saving throw (DC 25) or the soul takes control over the creature's body until it is no longer in contact with the amulet. If a creature is in contact with the amulet for 2 weeks or more, the creature's soul moves on to the afterlife and a copy of the soul trapped within the amulet permanently takes control over the creature's body until the body expires. Any number of creatures can be possessed at the same time.

If dispel magic (9th level or DC 19) is targeted on a creature who is in contact with the amulet, and the creature's body has not been permanently taken over, the creature regains control of its body and the amulet is thrown off the creature. If a creature's body has been permanently taken over, nothing happens.

The possession ability of the amulet is equivalent to the power of a 9th level spell.
