Burning all his soul in an instant should have killed anyone else, but Rowan had long learned to live without a soul, as to him, his soul could be seen as a clone and not the entirety of his being.
He could afford to live without a soul, but for this battle, his soul was too important to be extinguished, at least not until he was assured that Primordial Soul was dead.
Three strikes ago, he had already mastered Realm's Butcher Onslaught to a sublime level, and when he made the final infusion that burned what was left of his soul, he had mastered this technique beyond perfection, reaching a state that had exceeded the limits of this technique.
This was not a simple achievement, and Rowan, before this battle, would never have believed that he would be able to achieve something like this, because with the power and complexity of this technique, mastering it was equal to mastering a law to its Origin state.
