You manifest a Large, spiked "Battle-Top" in an unoccupied space (AC 18, 50 HP).

​Centrifugal Launch: Any creature that starts its turn within 10 feet of the top, or enters that area for the first time on a turn, must make a Strength Saving Throw. On a failure, it takes 6d8 Slashing damage and is pushed 15 feet away. On a success, it takes half damage and is not pushed.

​Vibration Zone: The area within 10 feet of the top is Difficult Terrain.

​Rip-Cord Movement (Bonus Action): You move the top up to 30 feet in a straight line. It can move through creatures' spaces; each creature it hits must make the Strength Saving Throw.
