Elemental ball

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 elemental shards. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 8d6 elemental (elemental type determined by a d8) damage on a failed save, or half as much damage on a successful one.

The elemental shards spread 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.
