8th-Circle Arcane and Wyrd (Conjuration)
Casting Time: 1 action
Range: 60 feet
Components: V, S
Duration: Concentration, up to 10 minutes
You banish a creature that you can see within range into a labyrinthine demiplane. The target remains there for the duration or until it escapes the maze. The target can use its action to attempt to escape. When it does so, it makes a DC 20 INT check. If it succeeds, it escapes, and the spell ends. When the spell ends, the target reappears in the space it left or, if that space is occupied, in the nearest unoccupied space.
