Void Storm

You summon Void fire in your hand. You throw it into an open space in an instant the fire hits and breaks an invisible barrier and breaks through the dimensional walls between worlds and a gateway opens with verticle swirling silver void fire. The Void is on the other side and a swirling storm of Void energies spins out of the Void. All creatures within 50ft of you are enveloped in the storm. All creatures take 5d8+4 force, 3d6+2 fire, and 3d12 psychic damage. All creatures are thrust upward 10ft and are dropped recieving 5d4+3 bludgeoning damage. The total damage is split in half and the rest is delt to who you decide up to 4 creatures.
