WHOOOSH!
Without care, Amon directly began the two steps, at once.
His cells began to expand and shrink and maddening speeds, his aether constantly refining itself as its fundamental structure sublimated and his aether pool widened.
The third step was called [Blood Sublimation] and normally, this step should've been a rather complex endeavour, not because of its complexity but due to how demanding it was.
In this step, Amon had to gather things called Bloodline Seeds and absorb them into his blood to elevate its quality and impurity while indirectly gaining all these bloodlines, which would obviously bloom from the seeds.
Here, there was no limit. He could fuse with one seed the same way he could fuse with a billion. It was all up to him to decide what kind of foundation he wanted.
