The dragon releases a 60-foot cone of sand and gravel. Creatures within the area must make a DC 22 Constitution saving throw, taking 35 (10d6) fire damage plus 35 (10d6) bludgeoning damage on a failed saving throw, or half as much damage on a successful one. A creature slain by this damage has its body pulverized; it can only be restored to life by true resurrection or wish.
