Aspect of the Crucible: Breath

You commune with the primordial power from the Crucible that flows within to exhale fire in a 15-foot cone. Each creature in that area must make a Dexterity saving throw, taking 3d6 fire damage on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 2nd.
