This spell fills a 10-foot-radius sphere with a brilliant flash of shimmering light. Creatures in the area must make a Dexterity saving throw. On a failed saving throw, a creature is blinded until the end of its next turn; on a success, a creature has disadvantage on attack rolls and ability checks until the end of its next turn, unless it is immune to being blinded.

Fiends and undead in the area take 3d6 radiant damage, with no saving throw.
