8th ring Primordial, Evocation
Brilliant sunlight flashes in a 60-foot-radius sphere centered on a point you choose within range. Each creature in that light must make a CON save. On a failed save, a creature takes 12d6 radiant damage and is blinded for 1 minute. On a successful save, it takes half as much damage and isn’t blinded by this spell. Undead have disadvantage on this save.
A creature blinded by this spell makes another CON save at the end of each of its turns. On a successful save, it is no longer blinded.
This spell dispels any darkness in its area that was created by a spell.
