You create a small wormhole on the base of your palm. Every creature in a 15ft cone must succeed on a Strength saving throw or be pulled into the wormhole and sent into an endless gravitational void. A creature starting it's turn inside the void takes 3d8 force damage and may attempt another Strength saving throw. On a successful save, the creature forcefully escapes and reappears in the space it left or in the nearest unoccupied space if that space is occupied.
