This is my first guide so give me some information what i can do.
Wukong i think is one of the best champions in league of legends.He is not overpowerd but also not underpower. I tryed that bulid very often and if you got all items you are realy g-g-g-godlike.

So good luck and have fun with Wukong.

Pro:
-Good dmg
-Tanky-bit
-Good assassin
-Much dmg at sqishys

Cons:
-No dmg against tanks or champions with a lot of live / deff
-Does not hold quite as much like an off tank Wukong
-Epensiv items

Every time in a team fight use ur ulti and if one of your team mates get in trubble help him!
So you will save you team mate and maybe you kill an enemy.If any enemys after a team fight got low live try to follow him and chase him down with Nimbus Strike and Crushing Blow.Also i team fights you have to focus there biggest dmg dealer.If you can´t get him down then just look that he goes out of the team fight and the konzentrat on other enemy but the biggest dmg dealer.

For farming just use all your spells out of cyclone.Nimbus Strike for more attackspeed and Crushing Blow to reduckt the aromr maybe of superminions.And Decoy to deal a bit dmg an many minions.Farming is very importent for this guide because the items are very expensiv.

Ghost and Flash are the best summoner spells for Wukong.Flash could be used very nice for a tower dive and for escaping.Ghost give you some nice movement speed for a short time wich you can combinate wiht cyclon it is also good for esceping.
Some other good summoner spells for wukong are:

-exhaust
-ignite
-heal
-teleport
-cleasne
bad spells are:

-revive
-clarity
-smite
-rally
-clairvoyence

Pick Doran´s Blade for the beginning cause it gives you some attack you realy need and some healt the lifesteal is also very importent.The second item is Mercury´s Threads it gives you some magic resist and movement speed you realy need an a bit Tenacity.The next item ist Trinity Force it gives you a alot of effekts you realy need and a very nice slow.The Bloodthirster is great item for Wukong because it gives you a lot of attack dmg and a realy nice lifesteal.The next items is Sunfire Cap (only if the enemys have more ad´s)it gives you some healt you realy need and some armor or Banshee´s Veil (only if the enemys have more ap´s)it gives you a nice shield wich blocks on enemy spell and it gives some healt,mana and magicresist.The next item is The Black Cleaver wich gives you some attackspped and good attack dmg and a great passiv when you hit an enemy reduce the aromr of enemy traget by 15 for 5 seconds (3 stacks possible).The next item is Infinity Edge with with 80 attack dmg and 25% crit chance and the passiv is that your crit hits deal now 250% dmg instead of 200% crit dmg.

Greater Mark of Desolation give you some realy nice armor penetration wich helps you to take champions mit some armor but not realy much life realy fast down.Greater Seal of Resilience
gives you over 10 armor wich is very nice for Wukong against ads so try to play against ads.Greater Glyph of Alacrity gives you some attackspeed wich you need for 1 vs 1 fights start with nimbus strik to get near to the enemy and tehn use Crusihing Blow to reduce the enemys armor then yous decoy so maybe the enemy use most of his spells on your decoy spell then youst attack him with basic attacks the slow of trinity force wil help you to take him down.Greater Glyph of Strength give you some early attack dmg wich is very nice for Wukongs ulti becaus your ulti deals 100% of your attack dmg.Greater Quint of Fortitude give you realy much life at the early game.
