Of course, Quinn knew this was going to be a tough battle, it was why he had done so much preparation beforehand. Why he had stayed in the tower for as long as possible making the best equipment he could possibly make.
There was a chance that he would regret the decision, as many lives would be lost while he was busy making all of the equipment, but now he knew he definitely had no regrets. If he didn't even have one of the pieces of the armour, then he was sure that he would have lost the fight.
This was easily Quinn's toughest fight as of yet. It took everything he had. Everything he had learned from his experience in various fights, against the vampire settlement, against the big four, the demons, and the celestials. All of those experiences and he had used in this match.
On top of that, he was using all of the skills of the armour and all of the experience he had gained in his previous fights during this fight. It was clear that he was giving it everything he had.
