The downside of the {Frostbite Aura} was its damage being weaker than {Burning Aura}. However, the major advantage of {Frostbite Aura} was the additional movement speed reduction! As a Spellcaster, the skill was more than helpful for Cheng Xue Yao, since the effect will be applied to all targets within the effective range. It was as similar to Zhang Yang's {Thunder Strike}, only that it was permanently active and can never be dispelled.
Naturally, Cheng Xue Yao was so delighted with the skill that she gave Zhang Yang a blow kiss. Zhang Yang tried his best to be oblivious to it but Fatty Han and Endless Starlight were extremely sensitive to that sort of thing. Sun Xin Yu and Han Ying Xue immediately rolled their eyes at him.
But then again, perhaps it was called for, since Zhang Yang had slightly "played" with her by pinching her cheeks when she had served him coffee at work. The woman must be trying to get the game straight with him.
