Gasoline for the 15 meter large billowing flame, Diesel for 35 meter range and nice smokey stream, and my personal favorite, napalm for a 50 meter reach and the fuel sticks to your mutant target.
Used to be my TO weapon not that long ago.
I do not plan to be a child molesting mutant.
I plan to be "a sip a couple of drops of blood of every week" mutant.
