Gravitational Whirl [reaction] Trigger A creature or object enters the area marked on the map; Effect The graviton prism increases the velocity of its rotation, dealing 1d12 bludgeoning damage. All creatures within 5 feet of the graviton prism must attempt a DC 17 basic Reflex save. On a failure, creatures are additionally pushed 5 feet away from the gravitational prism (10 feet on a critical failure). The graviton prism then rolls initiative.
Routine (1 action) The graviton prism hums as it continues to increase the rate at which it spins. All creatures within a 10-foot emanation of the prism must attempt a DC 17 basic Fortitude save. On a failure, a target is pushed back 5 feet (10 feet on a critical failure). Each subsequent time the graviton prism attempts its routine, the emanation increases by 5 feet (maximum of 25 feet).
