Ethereal Comet

A bright streak flashes from the sky as an ethereal comet plummets from orbit eviscerating the target and greeting them with into with a loud roar before an explosion of soul of flame scorches the area. Each creature in a 25-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 9d6 soul fire damage and becomes prone on a failed save, or half as much damage on a successful one.

The fire spreads around corners. It ignites flammable objects in the area that aren't being worn or carried.

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.
