Banish to the Void (EFA - B)

You attempt to banish one creature that you can see within range to the Far Realm. The target must succeed on a Charisma saving throw or be banished.

While banished, the target is incapacitated. The target remains banished until the spell ends, at which point the target reappears in the space it left or in the nearest unoccupied space if that space is occupied. When it returns, the creature must make a Wisdom saving throw, taking 3d12 psychic damage on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, you can target one additional creature for each slot level above 5th.
