You cleave through planar boundaries to banish your foe. Choose one creature you can see within range. It must make a Charisma saving throw. On a failed save, the creature is banished to its native plane or a harmless demiplane for 1 minute. If the target is native to your current plane, it instead takes 6d10 arcane damage and is stunned until the end of its next turn. The creature returns early if it takes damage or the spell ends prematurely.
