Hello my name is Dzungla00 i play on eu west. All credits for this build goes to airinho folow. He made the whole build.I saw him make a pentakill with this build and i maybe add it in the near future.

+Great damage output with his e
+If get fed nobody can kill him
+Can regain HP early game easy with w
+high mobility
+q is great for farming

-Low sustain
-can die easily in big teamfight
-w isn't useful because your ad yi

With these masteries yi does huge damage combined with wuju style. Dont worry about defense early game u have runes to protect you

Runes will give u some damage and some armor and magic resist.
greater mark of physical damage Gives more damage. If u think of going attack speed marks i don't think you will need that because your already buying early attack speed Gives u alot of armor early and you really need it on Master Yi because he's a bit squishy
Gives you magic resist if your up against heavy ap champs
More Damage

Doran's Blade Start with doran's blade is pretty good in top. It will give u extra hp and damage
Berserker's Greaves Give you attack speed which is really important on Master Yi and that makes 400 movement speed
Zeal It will give u more attack speed so you can do more damage faster
Vampiric Scepter Gives u life steal that combines nicelly with the attack speed and damage
static shiv This is a really important item on Master Yi. Most people just avoid it on him.But with that first critical strike enemy's will be like ....................
Bloodthirster I think this is one of my favorite items combined with static shiv. I say again enemise will be like ......
Blade of the Ruined King This has become a very popular item and i see at least one every game. MORE ATTACK SPEED, DAMAGE, LIFESTEAL what more do you want
Infinity Edge Gives you even more crit that cutts enemies open
Guardian Angel Is for some defense in big team fights if u get focused

In game u wanna farm and wait until you get your static shiv and Bloodthirster. But if u have easy match ups like Riven then you should get easy kills on them early game. You should try to 1v1 sometimes if you get focused. Wait for an opening to get a kill

This is my first build on mobafire please comment if there's something that i need to add or did something wrong Please say so i can improve. Dont down vote right away try it and see how it goes.Sorry for the runes i messed up i will probably fix it
