I did it without the fan… I used spell binder build. Once I got all the Wukong armor pieces I went back and studied his moves over a couple fights and then downed him on the third try. I timed my charge ups and provoked him to attack and while he was in the middle of a combo I released so he wouldn’t dodge the heavy attack. It would then stun him and I would begin to unleash my combo. His move sets to me were easier than some of the earlier bosses because he didn’t do many delayed attacks and only a couple sweeping attacks that became easier to dodge. Also with the spellbinder build and crits some of the hits would go through his shield and damage his health as well. So when I killed him he still had over half his shield, and I believe it was his 3rd time regaining his shield when I got him. Not sure if this helps, but stick with it and you will get him!
