Saving Throw: Reflex half

Hot winds swirl about you, and a faint aroma of brimstone sweeps over the area. A flickering yellow aura surrounds you and grows in intensity, shedding tremendous heat and light. Creatures around you stumble back from the heat. With a howling roar, you unleash a hellish blast of fire that melts steel and warps stone.

Only true masters of the Desert Wind school are capable of unleashing an inferno blast. You focus your internal ki into a blinding hot burst of fire that deals 100 points of fire damage to all creatures in the area. You are not harmed by your own inferno blast.
This maneuver is a supernatural ability.
