Tal’Sinoe’s Consumption

Her city aflame, the Gotrean army wading in the blood of her own, Tal’Sinoe broke.

When you cast this spell, you snuff out every flame of substantial size within 120 feet of you. After consuming nearby flames, you release an inferno in a 150-foot cone. Creatures in the area must make a Dexterity saving throw or take 10d8 fire damage, or half as much on a success. Flammable objects that aren't being worn or carried in the cone are set ablaze.

For every 5 foot cube of flame you consume when you cast the spell, the cone's size increases by 5 feet and the damage increases by 1d8.

It is said that with Tal’Sinoe’s moment of rage left a half mile of desert a glittering wasteland of ashen corpses— her flames, normally ruby, were rendered ice blue by cold anger and power.
