Devil's Breath

As you hold the spear, Devil's Breath, thrusted out in the direction of the desired attack, a thin line of flames shoots forth from the tip of the spear. Each creature in a 15-foot line must make a Dexterity saving throw. A creature takes 4d8 fire damage on a failed save, or half as much damage on a successful one.

The fire ignites any flammable objects in the area that aren't being worn or carried.
