Although the idea of using the "Lycanthropy Disease" bloodline curse to "tear" a Squib's "soul" was quite radical, Vizet's handling of it was remarkably skillful.
Whether it was Ritual Magic or Alchemy, which had extended and evolved from Ritual Magic, both shared one trait—they were extremely purpose-driven;
Under normal circumstances, once an alchemist understood their own needs, they would design around that premise, determine the Alchemy Magic Array, and prepare the corresponding alchemical materials.
According to Vizet's concept in the notebook, this amounted to using Ritual Magic and Alchemy to "attenuate" the "Lycanthropy Disease" bloodline curse, preserving the magical property related to "tearing the soul."
Vizet's vision was rather beautiful, but there were a great many uncertainties within it, and all kinds of side effects had to be avoided;
Damage caused by "tearing" the soul, for example, was instead a relatively easy problem to solve. After all, they had already developed the "Soul Healing Art," which could be used as a treatment method;
The manifestation of certain inhuman traits was also a possible situation. That side effect could be treated in combination with a "Voodoo Doll," removing those inhuman traits.
Vizet had listed the possible side effects, as well as the methods for resolving them after they appeared. His considerations could be said to be very comprehensive.
However, Snape could also tell that if they wanted to solve the side effects through these methods, it would require an enormous expenditure of manpower and resources;
The best method was still to prevent side effects from appearing at all. Only then could costs be reduced, along with the accidents and risks that might arise.
Before he knew it, Snape had already reached the end. Several lines of writing there had been specially marked, and the sight made his eyes widen at once.
