This is my first guide, not really sure how to write it out, so i just put my basic build and my current runes. I play wukong almost every time, he is one of my favorite champs, and this is my best build. Yes, it looks a bit like a normal ADC, but it is worth it. It makes wukong unstoppable as long as he has a teammate that can slow, stun or pull.

As shown on the chart, I start off by maxing out my E, which is the best attack Wukong has, of course, excluding his R. This is to open fights for him, and is useful when an enemy is escaping, and or, he is out of range for your other attacks. It is a gap closer, which deals a lot of damage. In a team fight, or any fight, this is my sequence: E,Q, W (ONLY IF MY HEALTH STARTS DROPPING BELOW 50%). And my ult (R) i use in team fights or if i really need it to run away, since it gives movement speed, and when i need the extra damage while i am on cool downs.

Just Flash and Ignite. Those two are really helpful throughout the entire game. I use it when i drop them below half health, and they begin running to the tower, i put ignite on them. Then i continue dealing damage as much as possible without diving the tower. Then ignite finishes my job. And flash is my escape route, but it also helps in catching runners.

as you can see, all the items on the build costs a lot of gold, which takes time to get. That is why Wukong must farm as much as he can. This means, that he is constantly shifting lanes after his tower (top) and mid tower are both down. This gives a great advantage because you can get more items quicker than people who just want kills. it is also a time saver, which keeps you less bored. It also serves as a healing device after you have your bloodthirster, and it makes you stronger farming those 40 minions extra after you have bought it.

Pros:
Wukong can solo top against almost anyone (its hard against Darius), since he is a bit tanky, meaning he isn't as squishy as other assassins.
He is a great champ to have in a team, because his ult deals damage and knocks up champs hit by it.
Cons:
He cannot solo 1vs5 (obviously), and he cannot tower dive very well.
If stunned, he is defenseless, and requires quick thinking of the use of his W.
