You summon the wrath of otherworldly forces to burn your enemies with radiant power.  A radiant pillar of light falls from the heavens, erupting on impact into a conflagration of radiant energy on a point within range.  Every creature within a 50 ft. radius, 200 ft. high cylinder of that point must succeed on a Dexterity saving throw.  On a failure, the creature takes 20d6 radiant damage and 20d6 force damage.  A creature takes half as much damage on a success.

All non-magical objects in the area that aren't being worn or carried are annihilated as the raw energy of the spell atomizes them.  Structures in the spells area take double damage.
