Master Yi is a champion of many possibilities. He can be played either AD or AP. But I prefer playing him as AD, he can be glass canon, tanky damage dealer or offtank. I think its best to build him as tanky damage dealer. You still have absolutely amazing damage, while having decent health with good MR and Armor.

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' 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.'' -- Soraka, the Starchild

Pros:

Great pusher/tower/farmer destroyer
Can't be slowed, exhausted or any kind of slows (when Ult is active)
Pretty easy to learn overall
Great escape/chase mechanism
CD resets/halves when you get a kill/assist(if Highlander active at that moment)

Cons:

Vulnerable to disables like blind, stun,suppress...
Low HP poll until you get Frozen Mallet(or other HP item)
Not so great in team fights
Squishy Champion

Exhaust

Exhaust is key to this build. Your number one difficulty as Yi will be keeping your enemies from running so that you can unload on them. Exhaust is the icing on the cake. A lot of kills will come from chasing down enemies as they are running away. The speed you get Phantom Dancer, and ghost help, but exhaust is what will make your enemy's escape downright impossible. Exhaust is also great for one on one fights with another powerful melee character. The reduced damage from the enemy can often times tip the scale in your favor. With the mastery points set as they are, you will also be reducing armor and magic resist for that extra little pow.

Ghost

It is for you to catch up to your enemies a lot faster when chasing. Or for use to escape the enemies. Ghost is another must-have. The vast majority of your kills early game will come from chasing enemies in your lane who you've already weakened. Late game, although you won't have a problem catching people because of your items, ghost let's you get to the other side of the map in a hurry, or chase down other people using ghost. Using this build, I have literally chased down slower enemies using ghost that have also exhausted me. That's the crazy speed we are talking here. Like I said, this build is all about getting to enemies quickly, slowing them down, and unloading your damage.

Masteries focus primarily on offense. Your primary role is to be a carry, so you need to be getting the kills for your team. Points are placed in the masteries relating to ghost and exhaust, so swap those out if you aren't using these spells. Also, you have a point in Utility Mastery for a reason... Grab buffs as often as possible!!

Double Strike

This passive is a beast when it comes to Melee DPS champions. Because this build is critical damage based, your critical is doubled every seven attacks. Also with your ultimate and items you have a lot of Attack Speed, so these 7 attacks are happen in matter of seconds.

Tips and tricks:
Try to stack your double strike before you gank so you hit double damage with first attack (If you're a jungler or a roamer).

Alpha Strike

Master Yi leaps across the battlefield with blinding speed, dealing magic damage to multiple units in his path with a chance to deal bonus magic damage to minions.

An amazing tool for jungling, farming, escaping and catching up. This skill allows you to pass by wolfs and wraiths in matter of 1 or 2 seconds. When maxed deals 300 damage, which is respectable, since you're not building on AP.

Tips And Tricks:
There is a picture explanation on how to use Alpha Strike in Gameplay section

Meditate

Master Yi rejuvinates his body by focus of mind, restoring health and increasing his armor and magic resistance for a short time.

Even thou I leave Meditate for last, its an incredible tool on Master Yi because of his squishiness and vulnerability. This skill is mostly underrated on most players.When at level 5 it heals you for 700 over 5 seconds, and in that time grants 300 Magic Resistance and Armor.

Tips and Tricks:
This skill grants you 300 Magic Resistance and Armor. Use it wisely against champions like Karthus when they use requirem.
This tool is amazing when it comes to survivability with low HP. You can trick your enemies into towerdiving you, granting yourself an easy kill.

Wuju Style

Master Yi becomes skilled in the art of Wuju, passively increasing the power of his physical attacks. Activating Wuju Style doubles the passive bonus damage for a short time, but the passive bonus is temporarily removed after the effect wears off.

This is pure ownage skill on Master Yi. Because of massive amounts of AD that this skill provides, I first take Phantom Dancer providing Attack Speed and Critical Chance. At level 5 only passive already gives 35 AD. When activated, you get 70 AD boost for 10 seconds.

Tips and Tricks:
Since last patch, this skill can be actived when in Alpha Strike form. Activate it while you're in Alpha Strike so your first hit will be affected by bonus.

Highlander

Master Yi moves with unparalleled agility, temporarily increasing Master Yi's movement and attack speeds as well as making him immune to all slowing effects. Additionally, killing a Champion refreshes all of Master Yi's cooldowns.

This skill is epic. This is your chase, escape and kill resource. You have a problem with enemies chasing you? Press R. Your enemies too fast for you? Press R. Not dealing damage fast enough? Press R. For what it offers, it has low cooldown. When maxed it gives 40% Movement Speed and 80% Attack Speed for 12 seconds. If thats not enough, this skill makes you slow immune when active.

Tips and Tricks:
If you kill an enemy during Highlander is active, all your cooldowns drop to 0 and you're skills are available again.
Combined with Wuju Style this skill is pure beast dealing damage in fast time frame. Use this in your advantage and backdoor when possible.

9x Greater Mark of Desolation

When it comes to marks penetration runes are pretty much first tier. Armor penetration is extremely useful early game. It helps you take down jungle faster and makes your ganks easier. Combined with Armor Penetration Quints, your attacks ignore almost 20 armor, while basic AD carries start with about 15.

9x Greater Seal Of Alacrity

These are for his Master Yi's passive because at his 7th strike he strikes twice so the faster he attacks the faster he gets to his 7th strike meaning dealing more damage.

9x Greater Glyph Of Celerity

These are for his skills to be used alot more so he can dominate and use his ult a lot more often.

3x Greater Quintessence Of Strength

These are for early game so at lvl 1 u'll have tons of damage already with his E's passive and if E is activated he gets twice the damage of E's passive.

I start with vampiric scepter so I wont need to recall and go back to base to heal.



Every pair of boots has its benefits, but attack speed is Xin's mojo. You want lots of it. Starting off with a dagger helps you heal faster with your passive and get your three talon strike in quickly for early ganks.



Wriggle's Lantern is good because you get damage with 15 lifesteal and 30 armor and its easier to kill minions since its 20% chance to deal 500 extra damage to monsters/minions which allows you to take buffs and dragons down in matter of seconds. Plus a vision ward that you can use everytime it disappears.



This is a great item for any physcial dps champion. However, in this build it is ESSENTIAL. I used to get this item immediately after boots, but its just not quite as effective without having some damage behind it. The biggest benefit to this item is the increased movement speed... The best increase in the game! You are going to be flying in and out of the jungle, all over the place, and you want the movement speed to match. Plus, it gives critical strike increases as well as (you guessed it) attack speed! Need I say more?



At this point, you are ready for the icing on the cake. The 250% critical strikes are nice, plus the pure damage will make you unstoppable. With all your items you can run everywhere with ease, chasing down the enemy and bending them to your will.



Frozen Mallet is your chase/defend item. While it grants you small AD boost, its great for chasing with passive slow combined with your ultimate. On top of that, this item grants you 700 health, which is great, since Yi has low HP pool.



Any melee wants a nice damage increase... But what about Yi's attack speed? The solution is to go for Black Cleaver. The armor reduction is really helpful in increasing your damage, plus it has a B.F. Sword. Need I say more? This is a better choice with the recent patch than the Bloodthirster, because you are getting more early attack speed.

I thank you looking up at my guide i hope this was helpful to you! Please Comment and Rate on this guide if it is not good just tell me what to change and all. Thank You!
