Skill Perception: {Bloody Spirit Revival}!! This is a technique that Marcellus created by mixing, {Bloody Reaction} with the {Undying Spirit Of Battle God Theogenes}!!
He uses his reactions to create a field around him in which he can dodge or block any move with the most menial of movements! Using his breathing pattern in combination with {Bloody Reaction} allowed him to create a move that heals his fatigue and body!
While making these minimalistic movements and his breathing pattern, he is able to gain back energy from taking easy, while making sure he doesn't take damage nor suffer wounds!
Since the purpose of this move is to conserve and regain energy during the middle of battle, he hasn't launched an attack because they take to much energy, from the brain to plan. And from the body to execute.
And, thanks to his vampire body, his physical wounds heal much faster in that time as well!!
