Blinding Beauty of Verenstra

You shroud your body in fantastic, lethal beauty. All creatures of your choice that can see you within 60 ft. must make a Charisma saving throw. Creatures that fail their saving throw by 5 or more are killed instantly. Creatures that fail their saving throw are blinded permanently and take 10d6 psychic damage. Creatures that succeed at their saving throw take no damage but are blinded for 1d4 round
