Sylas' eyes flashed open. He hadn't made the sort of progress he wanted to. Maybe it was because of his own Pride, but he didn't think it would be that hard once he got the idea.
In practice, though? It was a complete nightmare.
The problem with autophagy was that it would only target what your body deemed useless or a waste. Logically, if that was going to happen naturally, it would already have done so.
Sylas was a D-Grade, so anything that was inferior should be something his body targeted to get rid of.
But if it was that easy, then everyone who elevated themselves to a new level would experience a true rebirth of sorts. While this did happen on a somewhat smaller scale, it wasn't the complete overhaul that Sylas was looking for.
He was trying to use \[Madness Control] to force the issue a bit, but the level of understanding that would take was something he wasn't prepped for at all.
