Spatial Rift

Create a 30-ft. radius rift field centered on a point within range. The area is difficult terrain. When a creature starts its turn in the area or enters it for the first time on a turn, it must make a CON save. On a failed save, it takes 36 (8d8) force damage and you may teleport it up to 30 ft. to an unoccupied space you can see within the field. On a success, it takes half damage and is not teleported.
