Vortex of Souls

A black and lime green vortex of the world beyond opens in the skies like a dark and twisted aurora borealis. 4 beams of 40-foot-radius lime green light land at four different points you can see within range in spherical form, through which millions of pale green souls plummet to and through the earth screaming. Each creature in a 40-foot-radius sphere centered on each point you choose must make a Wisdom saving throw. The sphere spreads around corners. A creature takes 20d6 Necrotic damage and 20d6 psychic damage on a failed save, or half as much damage on a successful one. A creature in the area of more than one beam of the vortex is only affected only once. 

The spell blights and desecrates the area's it struck.
