But in reality, a true qualitative change couldn't be produced. This 'qualitative change' referred to a Mutation of Skills, like enhancements, observable under the Eye of Truth. Instead, it merely increased the power of the snowflakes in Wind Snow Homecoming, turning them into so-called hexagonal snowflakes. This increase could also be observed on the Energy power testing stakes.
However, testing was ultimately almost unnecessary. This was because the Snow Wolves that had consumed Heart of the Wolf, when compared to those that hadn't, not only advanced one Level themselves after using the hexagonal snowflakes, but the Skill Level of their Wind Snow Homecoming also increased by one Level. From its previous Proficiency, it had impressively advanced to the Proficient level.
Perhaps this particular Snow Wolf possessed better innate Talent than the other. Regardless, the effects of the Heart of the Wolf were undeniably demonstrated from another angle. That was enough.
