The light spreads around corners, and it lasts until the spell ends. When a creature moves into the spell's area for the first time on a turn or starts its turn there, that creature must succeed on a Constitution saving throw or suffer the following effects: it takes **4d10 radiant damage**, and it suffers **one level of exhaustion**. A creature that succeeds on its saving throw against this spell has disadvantage on saving throws against it until the spell ends or until the creature leaves the spell's area. --- ## At Higher Levels This spell does not have an upcast effect.
