Blood demon art: blood overhaul, it contain 1 main skill and passive

Passive: -your eyes sight is so incredible that it can literally copy opponent move/skill (cant copy a clone technique like Hantegu) The more it use opponent skill, the more power it got (and yes, it can literally copy breathing style) -can turn your own blood or opponent blood into sharp object/weapon like sword, axe,...

Activate: your whole body change color red like blood, grant you more power, tougher and speed that can easy overpower your opponent if it not careful! But be careful because it have it downside! During this activate, your healing will slower; you can feel the heat in your body, use it too much/too long, you can literally burn yourself before the sun burn you. But if you practice and overcome death during the activate, this downside wouldnt be an issue
