Apocalypse from the Sky (EFA - A)

You call on the darkest forces in the multiverse, which feed from and corrupt the pure, good energies of a powerful artifact of good. At the culmination of this vile ritual, the artifact disappears and destruction rains down upon the land and upon your own head.

All creatures and objects in a 10-mile radius centered on you take 10d6 fire, acid, or thunder damage (your choice), including you. In addition, you take 4d6 necrotic damage and 4d6 radiant damage, as you are caught in the battle between the dark forces and the good artifact.
