Tempest's Fury (Lightning)

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 lightning and thunder. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw.

A target takes 8d6 lightning damage, or half as much damage on a successful one. The lightning spreads around corners. 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 1200 feet.

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.
