Uller's Might!
-----
While desperately trying to survive against Uller and evading or blocking the powerful blows from Yukihime and Mikoto, Austr tried the best he could to fight back. His Blade clashed against Uller's body constantly, but he felt like he was growing more and more tired while Uller seemed completely fine! He was completely unaware that the two intelligent weapons also had the power to slowly drain energy from the enemies they wounded.
The blade of Uller had already slipped off Austr's cursed blade a few times, slashing his body and even piercing his armor with ease, like a hot knife through butter, and leaving countless bloody slashes over his body, which were quickly frozen.
However, now he was suddenly lured through the entire battle right where they wanted, into an enormous cloud made entirely out of poisonous gases, which was actually an extension of Vasilisius phantasmal body!
