A stream of starlight erupts from your hand, exploding into a burst of dazzling starlight at a point of your choice within range. Each creature in a 20-foot radius sphere centered on that point must make a Dexterity saving throw. A target takes 5d6 radiant damage on a failure and is blinded. On a successful save, the target takes half as much damage is not blinded.

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.
