You call down a blazing bolt of lightning to the ground, on contact it arcs out to 3 different points you can see within range. Each bolt creates a 40-foot-radius cylinder, rising 2 miles into the sky centered on each point you choose. Each of the cylinders spread around corners.. Each creature within target areas must make a dexterity saving throw. A creature takes 20d6 lightning damage and 20d6 thunder damage on a failed save, or half as much damage on a successful one. A creature in the area of more than one bolt is affected only once.

The spell damages objects in the area and ignites flammable objects that aren't being worn or carried.
