Void Rift

You create a rift in the fabric of reality that connects two points in space. The rift is a 20-foot diameter circle that extends from the ground to the sky. Anything that enters the rift disappears and reappears at the other end of the rift. You can see through the rift and use your action to make a melee weapon attack or cast a spell through it. Additionally, any creature that starts its turn within 10 feet of the rift takes 4d10 force damage.
