This is a detection ritual that Aiven obtained from the "Shadow Library," which, when combined with symbolic objects like a glass and clear water along with a specially concocted magic potion, can to some extent materialize a person's qualities.
The soul attributes of most wizards have no particular inclination, and what is materialized might just be a breeze or a small mist, all natural phenomena or objects in nature.
They can use both White Witchcraft and Black Witchcraft; only after long immersion in a particular type of Special Witchcraft will the soul develop some inclination, be it positive, negative, or strictly neutral.
Aiven is the same as well.
But a small number of innately gifted individuals are different.
They are born with a strong inclination, and some extreme individuals can't even use witchcraft from opposing fields, which can be described as insulation, but in their own inclined field, they are absolute geniuses.
Angie is precisely such a gifted individual!
