Passive: lose 5% current health with each kill, slain enemies fight for you for 10s. The stresses of battle are too much for the frame to handle and pieces break off with each skirmish, but even broken and abandoned they refuse to give up. Shattered bits of armor and flesh cling to their very last and press on, through the corpses that brought about their swiftly impending demise. Duration could be 20s at 200%, strength could increase damage significantly more to keep up in high level content, efficiency could increase health cost. It would ideally be able to propagate when damage is almost maxed out.
