A storm of brilliant radiance fills a 10-foot-radius, 40-foot-tall Cylinder centered on a point you choose (Concentration, 1 min). Each creature in the area when cast makes a CON save, taking 2d10 Radiant damage on a failure and having the Blinded condition until the end of its next turn. Each creature that starts its turn in the area must repeat the save. Higher Slot: +1d10 Radiant per slot above 5.
