Blast of Radiance

A bright light shoots from your pointing finger to a point you choose within range and then erupts a near blinding bright light. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 5d8 radiant damage on a failed save, or half as much damage on a successful one.

The light 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 5th level or higher, the damage increases by 1d8 for each slot level above 5th.
