Talisman of Ultimate Evil

Wondrous item, legendary (requires attunement by an evil cleric)

While wearing this talisman, you can use an action to banish any good-aligned divine spellcaster that you can see. The ground beneath the target opens and the victim falls into a pit, whereupon the crack slams shut.

There is no saving throw, but the banished creature can be restored with a wish. The talisman cannot be used in this way again until the following midnight.

A good-aligned creature cannot willingly approach within 5 ft. of the talisman without succeeding on a DC 16 Wisdom saving throw. If a divine spellcaster of a good alignment picks up the talisman, the spellcaster suffers 2d6 necrotic damage each round until dropping it.
