In order to do what he wanted, Sylas would have to raise his Classes to the next level, allowing them to elevate his body's Layers until they were able to withstand the might of the D-tier.
His understanding of his own body and his Layers were to the point he could literally reconstruct it from the ground up. But the act of actually evolving had to be done through this bridge.
Sylas wasn't yet at the point that he had evolved beyond Classes, but once again, he felt like his current Classes simply didn't suit the current him. Often, he used his Classes more so for the convenience of their individual Skills at any given time, but the thing was that his Rune Mastery was so powerful at this point that it felt worthless to try and use Skills when he could probably think of a Rune on the spot that would be more effective.
