Void wall

You summon a wall of pure unstable magic. This wall is 10 ft tall, and 30 ft long. Any creature that makes contact with the wall must make a WIS save against your spell DC. On a success, the creature is merely pushed back 5 ft away from the wall. On a failure, the creature is sent to a random plane of existence. This spell is considered forbidden magic (listed as necromancy as a place holder)
