Banishment

You attempt to send one creature you can see within range to another plane of existence. The target must succeed on a Charisma saving throw or be banished. If the target is native to the plane you're on, it vanishes to a harmless demiplane and is incapacitated there. If the target is native to a different plane, it is returned to its home plane (and if concentration is maintained for the full minute, it stays there).
