Hi! My name is treshii and Wukong is my main character nowadays . Before this build I tried a lot but I think this is the best and the most usefull .
First for all there are 3 periods in playing with Wukong:
1. Levelling (lvl 1-8)-> For to get the First Blood
2. Jungling (lvl 8-16)-> For the Money because the build is very moneyfocus
3. Finishing (lvl 16-18)-> For the Stat (:

Don't forget it !! You are just an Assassin-Support and not a Tank . You can attack but just one-by-one . For example: You see an enemy and you can attack him with a Nimbus Strike and after it a Clushing Blow and for the and you can escape with a Decoy . If you have the great build this "attackpack" can be deadly for the first or second time .

Wukong has a very good skill selection and in the battles you just want to use the Nimbus Strike, Clushing Blow and Decoy combination . When you are at level 6 you can also take in the Cyclone but this spell just good for those situations when you are infront of a lot of enemy . The Cyclone is also good for the hot moment when you want to escape and the Decoy is useless because the Cyclone when hit somebody it push him to the air and when they are in the air use Decoy and you are escaped .

So do not forget it:
Combos 1# (One target)
Nimbus Strike
Clushing Blow
Decoy

Combo 2# (More target)
Nimbus Strike
Clushing Blow
Cyclone
Decoy

The Items are very money-consuming so always be your eyes on the money-counter .
Your final build will be this:

For Wukong and for this build is the best Summoner Spells are the Ignite and the Flash .

Recommended Spells:This spell is the best for Wukong because when you make a big damage for somebody with a Combo but you can't kill hime burn him up with the Ignite and he will die (:
I always use Flash for all of my characters because it can be very helpful .

Also Good:Also good but I more like the Ignite than Exhaust because the Ignite is also make damag when the enemy is not there .
The Clarity is good for the Levelling period but after it is going to be useless . Also the same with the Heal .
The Smite is good for the Jungling period but after is sucks . And I think the monsters also easy to kill without this spell .
