In the Plague Jungles, Kong ruled as king. He could wield a unique, natural form of magic and he was driven by zealous ambition. The Plague Jungles were the ideal setting for fostering his growth - he thrived on challenges and flourished in adversity. However, when he had surmounted every obstacle and defeated every opponent, he grew restless. Worried that there was nothing left to overcome, he sought counsel with the monkey sage who lived behind the Grand Waterfall. The sage told him a tale of hairless monkeys to the north who, with wits and strength, bent the world to their will. Kong was overjoyed at the prospect of such worthy competition, and he immediately set out to the north, hoping that the sage's story was true.

Traveling north, he crossed the Southern Wastes and then the Great Barrier. Unaware of the League, he arrived outside the Institute of War where he found Master Yi in meditation. Kong was eager to test the strength of these northern warriors, so he challenged Yi to a duel. Intrigued by Kong, Yi decided to humor him. Within moments of his first strike, Kong knew he was no match for Yi. To be the best, he would need a mentor. He asked Yi to take him as a pupil and to show him the wonders of the northern lands. In return, he would honor Yi by becoming the greatest warrior Runeterra had ever seen. Admiring his passion, Yi agreed, but only under the condition that Kong would one day teach the lessons of Wuju to a pupil of his own. In the spirit of this agreement, he renamed Kong ''Wukong'', and gave him a weapon suited to his unusual nature - an enchanted staff that the young Doran had crafted. The weapon was an unrivalled masterpiece. After rigorous training, Wukong joined the League of Legends to fulfill his promise and show the world the true power of Wuju.

''The first step to wisdom and greatness is realizing how little you know.''
- The first lesson of Master Yi

Stome Skin:
Wukong's armor and magic resistance are increased by 4/6/8 for each nearby enemy champion.

Crushing Blow:
Wukong's next attack will deal 30 / 60 / 90 / 120 / 150 additional physical damage and will reduce the enemy's armor by 30% for 3 seconds.

Decoy:
Wukong becomes stealthed for 1.5 seconds and leaves an uncontrollable decoy that doesn't attack or move on the place he activated it. The decoy will deal 70 / 115 / 160 / 205 / 250 (+60% of ability power) magic damage to nearby enemies after 1.5 seconds.

Nimbus Strike:
Wukong dashes on a cloud toward a target enemy and sends out images to attack up to 2 additional enemies near his target, dealing 70 / 115 / 160 / 205 / 250 (+0.8 per bonus attack damage) physical damage to each enemy struck. He also gains a 20 / 25 / 30 / 35 / 40% attack speed bonus for 3 seconds after using this skill.

Cyclone (ultimate):
Wukong's staff grows outward and he spins it around for up to 4 seconds, dealing 20 / 110 / 200 (+1.0 per attack damage) damage every second and knocking up enemies once per cast. Wukong gains an additional 5% movement speed every half second for the duration of the spell, with the bonus disappearing once he stops spinning.

I always play with this runes if i pick wukong, cause the +normal dmg makes ur first skill harder and u are able to kill enemy champs with using nimbus strike + crushing blow and then escape with ur decoy. if u do this often, the champ will leave ur lane to heal, or u kill him.
a nice normal dmg is very important for the monkey king.
the cooldownreduction u need to us ur decoy often, witout skill it more then once and to use ur overpowered ulti often.

this summoner spells are nice, cause u are able to follow an enemy champion and kill him but u also are able to run away real nice or use exhaust just to slow the attspeed of ur enemy.

i picked so much ad masteries, cause this is an ad build :-) and i picked the utility masteries, cause u need the manareg for use the tactic explaned under "fights at starts of game"
often, cause lifereg always is nice and u need ur ulti very fast so used awareness.

at the start u should just try to hit the enemys one and then run away and then attack and run away ...
after a time they are hard damaged and have to leave or u´ll kill them.

at end u should jump into the teamfights and then u have 2 options:
option 1: use ur w skill and hint ur own, then attack later, the enemys wont focus u.
option 2: use ur ulti and throw them all into the air then defeat them.

if u want to conter vs a mage group, try it with HEXDRINKER or WIT´S END.
vs normal dmg guys you should try it with THORNAIL and MADRED´S BLOODRAZER.

i dont play wukong like an offtank or anything like this.
i play him like an assassin and this works nice, as an assassin i dont need so much survibility, just hard dmg and a lit bit lifesiege and spells tu run away and follow enemy champs easily.

if u are a nice xin player, it wont be hard for u to play wukong.
they are nearly the same, just xin does i lit bit more dmg and have a lit bit less live.

nimbus strike is one of the best farming abilitys ever, use it, deal 400 dmg, + increased attack speed. enough said? also use ur decoy to farm, it makes lot of dmg too.

sry for my short language and my bad english but im from germany and dont speak such a nice english ;-).
