Absolute Radiance

Choose a point within range. A 120-ft. radius burst of impossible light erupts there. Creatures of your choice in the area must make a CON save, taking 110 (20d10) radiant damage and becoming blinded for 1 minute on a failed save, or half damage only on a success. Magical darkness, invisibility, and illusions of Tier 10 or lower in the area end.
