You create a searing flash of blinding light. Each creature within range, other than you, must succeed on a Constitution saving throw or take 1d6 radiant damage and be blinded until your next turn. The light is sunlight. Undead and oozes have disadvantage on this saving throw.

The spell’s damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
