Arcane 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 arcane energy. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. On a failed save, a target takes 4d6 force damage and 4d6 thunder damage and is pushed 10 feet away from center of spell. On a successful save, the target takes half as much damage and isn’t pushed.

In addition, unsecured objects that are completely within the area of effect are automatically pushed 10 feet away from you by the spell’s effect, and the spell emits a thunderous boom audible out to 300 feet away from you by the spell’s effect.
