Fire Lungs

Somewhere in the mutant’s lungs, sacs of volatile chemicals hang. At will, the mutant may squirt these chemicals up into his mouth and spit them at his enemies. Once the chemicals mix together and encounter oxygen, they ignite in a stream of intensely hot, bright-free fire. The subject’s lips and the interior of his mouth appear thick, almost waxen, and his breath always has a sharp smell reminiscent of gasoline.
Type: Major positive.
Effect: This ability functions like a flamethrower, doing 3d6 points of fire damage in a 15-foot cone, or 5d6 points of fire damage in a 40-foot line, as the mutant chooses. Targets in the affected area may make a Reflex save (DC 10 + 1/2 the mutant’s character level + mutant’s Charisma modifier) to take half normal damage. The sacs only contain enough chemicals for three fiery shots, but they naturally refill themselves at a rate of one shot per hour.
Biotech: Implant, Graft.
