Volley of Fantastical Lights

A ball of smokey energy streak upward from your hand to a point of your choice within range and explodes into cascade of colorful lights in the air that then shoot down to the earth. Each creature in a 20-foot-radius cone centered from the initial explosion must make a Dexterity saving throw. A target takes 6d6 radiant damage on a failed save, or half as much damage on a successful one. In addition a creature that failed the save is blinded until the start of your next turn.

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.
