Anger of the Noonday Sun (EFA - A)

Your body explodes with radiance that bathes the area around you in sunlight. Any creature within the area of the spell that can see you must make a Dexterity saving throw or be blinded for 1 minute.

An undead creature caught within the spell's area within range must make a Dexterity saving throw. An undead creature takes 8d6 radiant damage on a failed save, or half as much damage on a successful one. In addition, the beam utterly destroys any undead creature specifically harmed by bright light (such as a vampire) if it fails its save.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the damage increases by 1d6 for each slot level above 6th
