Every Phantom had a set of abilities from the moment they embarked on this path. If they managed to survive long enough and pass several stages, they became strong enough for their Operator to gain abilities as well.
Over time, every Phantom and Operator would go through these stages if they reached a high enough level of power.
Obviously, the Evolution Vein was the key point. That was when the Phantom and Operator gained the power they had to use together. It was the first step toward true power that was only available to Second Rank Phantoms.
Adam still had a way to go to reach that level, but he was steadily approaching that peak, which was much more difficult to achieve and more significant for a Phantom than for monsters.
The Imaginary Cut became Adam's strongest weapon for a long time, but one ability was not all that the Evolution Vein was capable of.
Tremble. Tremble. Tremble.
The Evolution Vein actively trembled as it continued its growth along the Evolution Tree.
