Frost clung to the tips of Theron's hair, but he continued to glide on the wind. Casting his Dark Mana techniques here was especially difficult because of the volatile winds. It required more control than it would in a calm environment. A single misstep and he could scatter his own body into the wind with one casting of [Shadow Step].
But Theron also found it to be interesting training. He also found it curiously easy to kill the Ice Spirit Beasts down here despite being certain they were stronger than the ones on the surface.
Part of that was because he wasn't hiding his other abilities like [Entangling Silence], which basically allowed him to vanish in the winds, and [Entangling Clouds], which allowed him to walk on the air currents. But another part was because of how sharp his mind was and how easily he was able to use the environment to his benefit.
