When you see Zhin is an Opponent, Look at his Legendary. If he isn't using Retaliation, Feel free to shoot his counter from a distance as he will only have one block. Never Shoot a Retaliation Zhin though as most Heal from it... A LOT!
Zhin is annoyingly good at surviving fights using Counter and Billow. But keep in mind that while using his abilities he isn't a threat but a DISTRACTION. Just live him be and focus on an other enemy while you waith for his ability to expire
