Arcane Burst

You release a burst of raw arcane energy that detonates around you. All creatures within a 15ft radius centered on you must make a Strength saving throw. On a failed save, a creature takes 6d6 force damage and is pushed back to the edge of the radius. On a successful save, the creature takes half as much damage and is not pushed. The spell moves any unsecured objects out of the radius. The spell does not affect the caster.
