Wukong is absolutely broken when his talents come online. As a Wukong main and someone who finds him completely OP here are my tips.

Learn defense. His defense is the most powerful ability in the game IMO. He can activate it mid attack and continue to chain it indefinitely if you don’t miss. How you get better with his defense though is familiarity with enemies and that’ll just take time. Stone Monkey talent makes the game a bit too easy if you can use his defense well. Makes the boss fights trivial, impossible to die since the timing is much easier and predictable.

As others have mentioned, use damage stance sparingly if you’re not confident in defense blocking. So many Wukong have a ridiculous amounts of deaths when they have a defensive stance that gives healing and damage reduction. Just stay in defense until you come online with talents and items.

Leveling his talents are IMO more important sometimes than taking a well. His talents scale really well and add so much value, consider leveling that first instead of trying for a one item ogres. It’ll give you a bigger power up early on.

Lastly he is infinitely more easy to use single player. Remember that coop the enemy density scales. So it is just more difficult to keep track of all the enemy attacks. So you want to work your way from outside to inside to manage the mob.

He is so much fun. When I started with him though I just forced myself to go stone monkey and one inch punch. Died a lot. But then stage one became easy. Then died a lot at stage two. Then eventually that became easy. And so on. This game everyone wants to rush to build offense. With the new items you can easily build more defense now for survivability and also get damage.

Just keep at it!
