Dothian's Dual Inferno

Roaring flames burst from each of your two outstretched hands in two separate 30-foot cones, oriented in a direction of your choosing. A creature caught within either of these cones must make a Dexterity saving throw, taking 6d6 fire damage on a failed save or half on a successful save. Alternatively, when you cast the spell, you can place your hands together and create one single cone. Creatures caught in this concentrated cone of fire must make a Dexterity saving throw, taking 9d6 fire damage on a failure or half on a success.

At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, the damage for both types of cone increases by 1d6 for each slot above 3rd.
