A blinding light flashes from your weapon, and for a split second, it transforms into burning magma.

You convert your ki into fiery energy, allowing it to flow down your arms and across your weapon. Until the end of your turn, your melee attacks deal an extra 3d6 points of fire damage + 1 point per initiator level.
This maneuver is a supernatural ability.
