Once a day, use your action to open a 20ft radius rift within 30ft of you. Enemies in range must make a Con save. On fail, take 2d6 Force Damage and get pulled toward sphere in straight line, ending in an unoccupied space closest to the center as possible. On success, take half damage and aren't pulled. When sphere disappears, all creatures who failed save are knocked prone. Can also use rift to teleport to the rift instead of pulling enemies.
