Comet Barrage

Call down four orbs of celestial ice causing them to crash into the earth at four locations you can see within range. Each creature in a 40-foot-radius sphere centered on each point you choose must make a Dexterity saving throw. The sphere spreads around corners. A creature takes 20d6 cold damage and 20d6 bludgeoning damage on a failed save, or half as much damage on a successful one. A creature caught in the blast radius of more than one comet is affected only once.

The spell damages objects in the area and sources of water freeze solid.
