Eldritch Explosion

A bright streak flashes from your pointing finger to a point you choose within range and then blossoms with a low roar into an explosion of flame. Each creature in a 20-foot-radius sphere centered on that point must make a Strength saving throw. On a failed save a target takes 8d6 force damage and gets pushed 5 feets from the center of the explosion, or half as much damage and doesn't gets pushed on a successful one.

All objects in the area of the explosion gets pushed 10 feets away from the center.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
