A word of warning. Most of your games will end fast ;P
This is my guide to Wukong, I win almost every game even when I have a feeder teammate. It's EXTREMELY easy to carry with Wukong after a certain point. Now I have to mention this is a build for 3s, and while it does work on 5s, it's much easier to win in 3s with this build. You will get tons of hatred. But usually it's more like your team getting hatred because you're carrying so much and 1v3ing by level 14 :P. Tryndamere becomes a small worry to you, and there's not many champs who can take you as long as you play smart from the start (while a little aggressive, since you can normally fool a few people into coming after you with low health, which results in their death.) Give the build a try and I guarantee you'll enjoy Wukong even more than you did before.
Pros / Cons
Great harass early/mid game
Escapes damage well with Decoy.
Extremely good survivability
Very good at clearing lanes mid/late game
Gets focused instantly(Solved by Decoy)
Not a great early game farmer because of melee
People rage (Could be a pro?)
The runes I choose are built around early game domination. Since in 3s your early game determines the rest of your game, and while Wukong is formidable even after it's been 15 minutes without any kills or any substantial shutting out of your enemies, Wukong becomes a major force to be reckoned with if you can get a few kills early.
The Greater Quintessence of Desolationx9 and Greater Mark of Desolationx9 easily put you over the 20 cap so you can easily ignore all armor early game, resulting in squishies being halfed at level 2.
The Greater Seal of Armorx9 and Greater Glyph of Magic Resistx9 provide you with the extra tankiness to be able to pull off harassment until level 3 without dying. Once you hit 3 you should never be hurt after harassing, unless it's a Caitlyn who knows how to aim.
The masteries are also aimed at giving you the most damage and a bit of lifesteal right off the bat. The CD and crit is also much appreciated. The extra def/mres from defense tree only adds to your tankiness.
You always want to open up with a Doran's Blade which gives you a very significant health and damage increase right off the bat. You'll sell it later so don't worry.
The second time you go back hopefully you can buy Sheen and your Boots of Speed if not your full Tier 2 boots. For boots it depends on the team. If you notice a lot of melee champs such as Tryndamere Jax Nasus Xin Zhao or such, then you definitely want to grab Ninja Tabi Not only do these actually help you harass by dodging minions early game, but they will save your life on many occasions where your Decoy is on cooldown and you dodge the last hit before being able to use it again. If the team has heavy cc such as Morgana Lux or others, grab Mercury's Treads.
On your third trip back you should be able to buy your Zeal If you don't have tier 2 boots by now and have exactly 1195 or close, buy these first. As the movement will help cover for your slowness.
After this you should only go back once you have 1615 so you can finish off your Trinity Force.
After getting TF, you're going to pick up a Giant's Belt For that instant boost to HP.
The next time you go back try to either get Atma's Impaler or parts of it. Finish this before finishing your Warmog's Armor.
After Warmog's it's all situational. If you're roflstomping go straight for Infinity Edge. If you're getting hurt badly but still able to pull out of a fight at the end, grab The Bloodthirster. Frozen Mallet is a definite want. However you can't have all three, and you should only mix FM in if you have problems with people getting away, or you don't have enough HP. For games where your team can push without you after you get an ace, grab FM&IE, for games where your other two teammates are both either mages, or people without aspeed, grab BT&FM, and for games where you never even get hurt because you're killing them too fast, grab IE&BT.
The skill sequence is self explanatory, The Nimbus Strike first allows you to get those early ganks and first bloods, simply dash in, auto attack once, bam thats a halfed Annie And since the skill hits up to 3 enemies, you've effectively hurt all three members of their team, allowing for your teammates to attack either the one you're attacking, or the other two of their team for easy damage. The second spell you chose is extremely optional. If you notice you can't harass at all because you get extremely hurt by stuns and ranged carries, grab Decoy second over Crushing Blow. You'll want to max Crushing blow first since it not only puts out insane damage before and after you get sheen, but it decreases the enemies armor, combine that with the increased attack speed you get after dashing in with Nimbus Strike and your ability to get away with Decoy and you are now a harassment machine.
Why build Wukong this way?
It's simple. Wukong excels at taking damage, while dishing out more. So why not build him to that effect? I used to be like everybody else who built wukong full damage and never bought health. Sure you would do great some games, but alot of games you were just too squishy and couldn't turn games around, and would end up losing. With this build if you ever lose a game it's not your fault if you're playing smart. Just don't get cocky when you have a lead. A few of your deaths can be a HUGE bonus to the other team.
Wukong is an amazing champ for 3v3. I'd definitely place him in God tier, only people who can beat me (with difficulty) would be a very well played Lee Sin, or an average Sion Cuz yknow, it's Sion.
The way I play him is extremely effective, and I almost always have a 9/1 win ratio on my Match history page. Never going negative in kills, and always carrying my team to victory, with the odd Vayne or two killstealing me and ending up carrying along with me :P
I'm not level 30 yet so I've yet to play him in Ranked. I play against plenty of 30's though, so don't let that fool you.
