Wyrdborne Apocolypse

Bursts of energy plummet to the ground at five different points you can see within range. Each creature in a 40-foot-radius Sphere centered on each of those points makes a Dexterity saving throw. A creature takes 20d10 damage on a failed save or half as much damage on a successful one. A creature in the area of more than one Sphere is affected only once.

A nonmagical object that isn’t being worn or carried also takes the damage. The areas where the Spheres land become Difficult Terrain.
