Decree: Sun Collapse

A massive glowing orb of light appears 50ft over a point to can see within range. Invisibility within 100ft of the orb is dispelled. A creature within 100ft of the orb that looks at it directly must make a CON 15 save or become blinded for 1 minute. Darkness within 150ft becomes brightly lit, and 50ft beyond that is partially lit. At the end of each of your turns, and for the duration of this spell, you can choose to either move the orb 10ft in any direction, or send it to a point that is within 50ft from the orb, and upon reaching that point it will detonate, dealing 10d6 radiant damage in a 40ft sphere, all creatures in that sphere must make a Dexterity saving throw against your spell save DC, on a success they take half damage. Interacting with the orb in any way will cause it to prematurely explode, for the same effect (Example: An arrow hitting it, or concentration being broken).
