You spray golden particles in a 15-foot cone, covering all creatures and objects in that area. Each creature in the area must succeed a Constitution saving throw or be blinded for the duration. A creature blinded by this spell can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. Each creature within the area, whether or not it succeeds on its saving throw, can’t benefit from being invisible for the duration.
