Aevi's Strato-smash

Reaching to the sky, you call a blazing comet of fire plummeting to the ground at one point you can see within range. Each creature in a 20-foot-radius sphere centered on the point you choose must make a Dexterity saving throw. The sphere spreads around corners. A creature takes 14d6 fire damage and 6d6 bludgeoning damage on a failed save, or half as much damage on a successful one.

The spell damages objects in the area and ignites flammable objects that aren't being worn or carried.
