This was the first time Gary had consciously done something to increase his Grade. Last time, he had simply selected his Class, and it had surprisingly upgraded him to a Knight Grade Werewolf as well. Since the change in appearance was mostly due to choosing the Warrior Class, Gary hoped that he would be able to gain the system benefits without any pain.
He wasn’t completely wrong. His body didn’t change much, the teenager only experienced a weird feeling, yet he had gotten somewhat used to it given his frequent transformation. However, what he was unprepared for was the experience of what could only be described as his brain melting, being constantly poked from the inside with a hot rod.
It was far more painful than when he had learned new skills, even worse, it lasted longer. The Werewolf immediately collapsed onto the ground. He grabbed his head, and instinctively clawed at it, having to stop himself, as he realised before he knew it, that his hands had already transformed.
