This is my Master Yi build guide, it's primarily based off of attack speed and some critical strike damage. I enjoy playing Master Yi and find critical strike to be much more effective than just straight damage. My summoner name is HermnerShepard I am currently in Silver 2.

The Life steal quints help you sustain and make your way through the early jungle clears. The marks of attack speed will really help you activate your critical strike chances. The seals of armor will help take away some of the hits you take from most AD jungler's. The 1 seal of mana regen. is just for the mana hunger early. The glyph's of AD are solely there for early jungle clears.

The Masteries I used are primarily based on hitting and crit-ing as much as possible. The extra mana regen. is also very important due to how much mana Master yi expends with his abilities. Then the extra health regen. and damage done to attackers isn't necessarily needed but I believe it will allow you a faster jungle clear time.

You will be first maxing your Q, which is an extremely important and unique skill that allows Master Yi to be as good as he is. Picking up meditate early is a great choice because it allows you to make it out of the jungle much more quickly. The true damage granted from E is great as well, so maxing it second is another good choice. Then of course picking up your ult when possible is extremely important.

Pro:
-Quickest Jungle clear times
-Great dueling potential
-Natural jungle sustain
-Scales hard into late game
Con:
-Weak gank potential
-Shut down by most CC
-Long cooldowns on most abilities without Highlander active
