Bright Lamp

You create a huge lamp head that creates a 20-foot-radius sphere of bright, yellow light centered on a point within range. The light spreads around corners, and its area is heavily obscured by light. The bright blast remains for only a few moments, but it's extremely bright.

Each creature that is completely within the cloud at the start of its turn must make a Dexterity saving throw against the light. On a failed save, the creature becomes blinded and takes 2d6 radiant damage. Creatures that don't need to see or are immune to radiance automatically succeed on this saving throw.
