Unstable Rift

You create a point of unstable energy at a point within range that you can see. Each creature within a 20ft radius sphere centered on that point must make an Intelligence saving throw as a sphere of black fog streaked with purple energy expands from the point. This emanation ignores cover. A target takes 5d6 psychic damage on a failed save, half on a success. At the start of your next turn, the sphere collapses inward to the point you created and explodes. Each creature in a 20ft radius sphere centered on that point must make a Dexterity saving throw as a wave of force ripples through the air. A target takes 5d6 force damage on a failed save, or half on a success.
