Bombardment

Vibrant orbs of magical power plummet to the ground at four different points you can see within range. Each creature in a 60-foot-radius sphere centered on each point you choose must make a Dexterity saving throw. The sphere spreads around corners. A creature takes 20d8 force damage on a failed save, or half as much damage on a successful one. A creature in the area of more than burst is affected only once.

The spell damages objects in the area and turns the surrounding area and any enemies that take lethal damage into glass.
