Crescent Wave

You sweep your hand through the air, sending an arc of sweeping radiant energy before you in a 30 foot cone. Targets in this cone must make a Constitution saving throw. On a failed save, the target takes 6d6 radiant damage, and is blinded for 1 minute. A blinded target may attempt the save again at the end of each of its turns, ending the effect on itself on a success. If a target succeeds on its save, it takes half damage and isn't blinded.

Lycanthropes and Undead have disadvantage on the initial save. 

At higher levels: When cast at 4th level or higher, this spell's damage increases by 1d6 for each level beyond 3rd.
