Banishing Bell

Wondrous item, very rare

This small silver bell has 3 charges. As an action, you can ring the bell and expend 1 charge to banish evil so long as the bell’s note hangs in the air. Each creature within 90 feet native to a plane of existence other than the one you’re on must make a DC 15 Charisma saving throw if it can hear the bell. If the creature fails, it is banished, returning to its home plane. At the start of each banished creature’s turn, it makes another saving throw to shake the last echoes from its mind; on a success, it returns to the plane from which it was banished. Each creature that returns in this way reappears in the space it left or in the nearest unoccupied space if that space is occupied after 1 minute it if it has not succeeded on its saving throw yet. A dispel magic spell cast on the banished creature or the spot it departed from causes the creature to return immediately. When a creature succeeds on its saving throw against the bell or it returns from being banished by the bell, it is immune to the effects of the bell until the next dawn.

The bell regains 1d4 – 1 charges each day at dawn.
