Divine Radiance

You unleash a destructive wave of divine power in a 25-foot cone. Each creature in the area must make a Dexterity saving throw. On a failed save, a target takes 5d6 radiant damage, and is knocked prone. On a successful save, a target takes half as much damage and isn’t knocked prone.

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.
