thats right hes not asian infact hes only a imaginary leauge of legends champion that can kill whole teams if played right and smart. You have to play at least 30 rounds with master yi to understand him and when to initiate/ and how squishy he is and that any stun can ruin him.

do not farm if they can harras you and you dont have life steal yet. if this happens farm when minions reach your turrent

Runes: crit chance all the way :P

Jungling: you will jungle easy when you reach a vamp scepter though dragon will be hard to solo

most people do alpha strike first but with this critical hit build he needs dmg asap and alpha strike is useful for teleporting to the guy end game anyway.

Activate wuju style in a fight forget about the after effect.

your ulti has to be timed. If you know they will run back to turrent and you cant kill them dont use ulti. only use it for sure kills like with exhuast and a stun partner.

you have 30% crit hit chance at lvl 1 which is alot of dmg with wuju style.

Start with Brawlers gloves + 2 hp potions.
Get boots now and and a potion if neeeded
Now get a zeal and you'll have 400 movespeed
Get some life steal from a vamp scepter to lane and so you dont need potions any more
Now finish shoes to berserker greaves.
Finish the Phantom dancer. upgrade zeal to emblem of valour.
Now get a infinity egde.
Now a last whisper.

If you do good and dont need a ga get a blood thirster. then sell emblem of valour and get a guardian angel
If you die too fast get a guardian angel
Now when you have about 2800-2900 sell emblem and get a blood thirster

target squishies first then tanks exhaust the dmg dealers on team if needed and exhaust to get kills/ live

STay safe from the first ccs/ burst dmg or you will die without kills.

Alpha strike to squishies and try to come into the team fight from the back.

Don't turrent dive if they have a cc skill or you can't kill/run in time

Lane with a stun/slow champion or tank if your afraid
