This is balthazars rework, the added shackles and chains tie into his past as a demonic prisoner. Each of those shackles have spikes within them, similar to an iron maiden to ensure that the shackles bite into his body and limit his movement... this however after several hundred thousand years failed, after his pain was virtually numbed, from his tolerance gradually increasing... After he broke free, he mutilated a hellturned arstoric Rebuke (An incredibly powerful kind of hell-warlock), using his claws, chains, and tail clasp (as a mace)... he Ripped its Meburic crystal (the source of its power and "life" drive) from its body, and used it to cut out his own heart from his chest, He then stabbed it with the crystal in front of himself. This, not only revived and healed him, but in addition to his own abilities granted him the abilities of the warlock, however the power granted to him came at the heavy cost of his sanity. After obtaining the power of the warlock, this allowed him to open up sigils to the mortal realms and flee hell... meaning that we have now ended up with an obsurdly powerful unhinged little immortal demon that feels virtually no pain. Did someone call mary sue? I think we might have one of her character here...
