Urge to Bleed (3.5e Maneuver)

''Look at all that blood trapped under its skin. It just wants to be freed, you should help it get out!''

Make a normal melee attack. You ignore a number of points of natural armor equal to your initiator level. If you ignore all their natural armor (or they don't have any natural armor bonus) you deal an additional 1 point of damage per initiator level as the blood bursts out rapidly.
