Cynder's Molten Inferno

Raising your hands in the air, magical fire is summoned from the elemental plane of fire and engulfs you. The temperature within 120 ft. of you becomes hot enough to melt stone and metal. You can target up to four creatures, they and any creatures within a 40 -foot-radius must make Dexterity saving throw. The heat spreads around corners. A creature takes 20d6 fire damage and 20d6 force damage on a failed save, or half as much damage on a successful one. A targeted creature can only be affected only once.

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