Look. I don't want to go into a crazy amount of detail as to why Master Yi is overpowered. He's insanely powerful if fed, his ultimate is cheap. He really is a game changer if played correctly. The main objective is to get fed and carry the team. The best way to do this is to have a friend to lane with and coordinate ganks early game and have them LET YOU FEED. Master Yi is not a difficult hero to play, but he can be difficult to master the art of stepping in and out of combat, switching targets, and running away when appropriate. Moral of what has been said so far, Master Yi is kind of a scared puppy, with a bite bigger than his bark if you are skilled and fed enough to take him that far. I hope you enjoy the rest of the guide, good luck and have fun carrying teams.

This build is based around a "Laneing Yi." You may be able to transfer the build to benefit a jungle build but try that on your own time. Now, Let's take a quick overview of how to set up a Master Yi pre-game.

Keeper of the ancient art of Wuju, Master Yi is a mystical warrior from the isle of Ionia. He descended from one of the few tribes dedicated to the preservation of Wuju, a martial art founded with the principles of absolute spiritual awareness of one's self and one's enemy. When the armies of Noxus invaded Ionia, Master Yi joined in the Ionian defense to fight the craven enemy, bringing his village honor through his unparalleled mastery of the blade. The ensuing battles ravaged the land, but no conflict inflicted as much horror as the day the armies of Noxus closed in on Yi's village. Left undefended, the village became the unfortunate test subject of the latest invention by an up-and-coming chemist, now known as Singed. The remains of the village that Master Yi returned to were so horrific that it remains a festering scar on Ionian history. To this day, no Ionian will ever publicly speak of what occurred.

After the Noxian invasion was contained, Master Yi fell into a deep isolation. For years, he trained morning to night, speaking to no one and refusing offers of consolation by fellow Ionians. The only thing stopping him from madly charging into Noxus battle lines headfirst was his pledge to keep the Wuju style alive. Even though he seethed with impatience, his rage became a tool for sharpening his practice of Wuju, developing stronger and deadlier skills for his eventual vengeance. The only thing that roused him was news of the League's formation, and Noxus's subsequent enrollment in the League. Master Yi now brings his mastery of the blade to the League of Legends with unflinching purpose: to avenge his kinfolk and end the predations of the Noxus once and for all.

"The art of Wuju lives on in Master Yi, and is plunged through the hearts of his foes."

Pros:
You are extremely powerful late game
Escape slows via [*]Highlander
Great push hero for turrets
Easy to learn

Cons:
Extremely vulnerable to gank early game.
Squishy late game
Frowned upon for being "cheap"
Often focused by enemy team

Listen, Master Yi is an awesome hero. He's a monster of an assassin and an amazing pusher. He is probably one of the best carries this game has. But he is cheap, you will get hated on for using him. The only thing that sets a good Yi from a bad Yi is knowledge, practice, and skill. So show people you know what you're doing, get out there and make people hate you :]

Why so much Critical Damage?
[*]Infinity Edge Provides you with Critical Strike and Critical Damage increase, ontop of its +80 Attack Damage. The weapon screams for Master Yi and this build. Infinity Edge is merely adding more power to you swings with the high crit increase. With a high crit chance in late game, all of your runes, items, and masteries that provide you with bonus critical damage give you around 500 to 900 crits on enemy heroes (depending on their armor and such). You cut through people. End of explanation.

Master Yi CANNOT initiate a 5v5 team fight. He will be focused if he is fed because he is squishy and will die very quickly. You are a threat and honestly you are probably their BIGGEST threat. So remember to coordinate with your team. Be nice, don't kill steal and if you do just apologize. Good teamwork will benefit the team and will offer you the distraction you need to sneak into the fight and kill their team before they can even realize you were there.

I hope you have enjoyed this guide. I've been playing Master Yi since level 1 and I love him. I also play Caitlyn for insane games but that's another guide. I hope you have learned something useful from this and good luck mastering this way of the Wuju!
