Symphony of Ruin

A crackling boom erupts from a point you choose within range. Each creature in a 20-foot-radius Sphere centered on that point makes a Dexterity saving throw, taking 8d6 Thunder damage on a failed save or half as much damage on a successful one.

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