Meteor Swarm

Blazing orbs of fire plummet to the ground at four different points you can see within range. Each creature in a 40-foot-radius Sphere centered on each point must make a Dexterity save, taking 20d6 Fire damage and 20d6 Bludgeoning damage on failure, half on success. A creature in the area of more than one fiery burst is affected only once.
