Harsh Light of Summer’s Glare 2014
8th-level enchantment
You emit a burst of brilliant light, which bears down oppressively upon all creatures within range that can see you. Creatures with darkvision that fail a Constitution saving throw are blinded and stunned. Creatures without darkvision that fail a Constitution saving throw are blinded. This is not a gaze attack, and it cannot be avoided by averting one’s eyes or wearing a blindfold.
