On the parchment scroll recording Soul Sleight cultivation, Frod had once read an account that clearly stated that, besides proceeding step by step, there was another way to learn Soul Sleight:
By killing undead and absorbing their special energy, one could aid the cultivation of Soul Sleight.
This method came with many restrictions. The chaotic energy carried by the undead could very easily lead to one's own corruption.
Moreover, the Soul Sleight gained through absorbing an undead had to match an ability that undead itself possessed.
For instance, if an undead only knew the ability "Possession," then after absorbing it through special means, the first Soul Sleight one learned could only be Possession.
Most importantly, the effects of absorbed Soul Sleight were not necessarily very good. Cultivating it oneself offered more choices and could also prevent corruption.
Previously, Frod had never considered using such a method.
But now, he had heard of Lady Xila, the spider-transforming undead.
Spider-transforming undead were special undead. So-called special undead possessed something that distinguished them from ordinary undead—perhaps they exerted greater influence over the material world, or perhaps they had special abilities unlike those of ordinary undead.
If one killed a special undead, the Soul Sleight absorbed from it was highly likely to be that being's special ability, and its strength would be far greater than that of ordinary Soul Sleight!
Of course, the chaotic energy brought by special undead would also be more turbulent, and the odds of corruption would rise accordingly.
Yet corruption was precisely what Frod feared least.
With Prelude of Reincarnation, even if he became corrupted, it could pull him back. Still, if he could avoid corruption, he should. Truly becoming corrupted would not only waste White Light Bullets, but the ability he absorbed would not return either.
It was precisely
