Arcane Eruption

A bright, white streak flashes from your pointing finger to a point you choose within range and then detonates with a whining shriek 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 3d6 force damage and 3d6 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 the spell’s effect.

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