Banish Slime

You attempt to send one slime that 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 fails its saving throw, you send it to a harmless demiplane. While in this demiplane, the target is confused. The demiplane takes on the form of a giant labyrinth. It contains all the materials needed for the target to survive. The maze is 500x500ft. in size. The target is trapped until it finds the exit to the maze.

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.
