Altienne's Lucky Star

You summon a small sparkling projectile from above, descending upon a point within range and then bursting in a brilliant explosion of starlight.  Each creature in a 15-foot sphere must make a Constitution saving throw.  A target takes 4d8 radiant damage on a failed save and is blinded until the end of your next turn.  A target who succeeds takes half damage and is not blinded.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level above 3rd.
