Void Pulse

You make an "X" in front of you with your arms, then break it quickly bringing your arms out at your sides. A pulse of silver, black, and white energy is pulsed through the space around you reaching out to 50ft. All creatures are affected by this spell including allies. All creatures are pushed back 15ft. They are hit with 4d8+4 force, and 3d12+2 psychic damage. Any and all portals, gateways, and/or teleportation spells of any kind are dispelled if within 50ft.
