As a true and undeniable master of the blade, you may unleash the heartrend, the ultimate Battleflow maneuver. This strike requires an opponent whose muscular and internal systems have sustained at least 60% damage each. This threshold is reduced by 10% for each muscular or internal malady plaguing the target, respectively per system, to a minimum of 20% internal and muscular damage (at 4 afflictions). When such a foe presents itself, delivering this manuever will send your blade through their heart, causing instant and agonising death.
