For the first time, the werewolf began to panic when he saw the ice cracking. After all, he lost the sense of touch due to the massive cold. The situation was getting harder for them, even though he had assumed that nothing would stop them...
At that point in time, Billy realized that those guys were only the nearest and easiest enemies that Uvish found and that he could manipulate. They probably had a lot of knowledge regarding all those things that Uvish was dealing with, but they weren't that stupidly strong. He didn't realize that Uvish was just using them to cause Billy some problems.
In any case, the idea of combining ice and gravity magic on the Blade of the glaive worked well. The only downside was that he had to keep touching the enemy for the skill to work. Unfortunately, that gave the enemy to shout, making Billy dizzy and feel like he almost went dead.
