Brimstone Volley

A bright flash appears in the sky, followed by large, flaming rocks that rain from the sky. The area of the storm is within a 50 foot radius, and each creature in the area must make a DC 15  Constitution saving throw on each of its turns while it is in the radius. It takes 5d12 fire damage on a failed save, or half as much damage on a successful one.

Rocks will be piled up all around the area, which are still extremely hot. Any creature that touches or makes any form of contact with the rock, without armor, must make a DC 11 Constitution saving throw or take 2d12 damage.
