Introduction



Master Yi is a champion of many possibilities. He can be played either AD or AP. When played 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.


Master Yi's story

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."

How to counter Cons



Not so great in team fights

You should not initiate first. Master Yi is already squishy and if you go first, you won't do anything for your team except feed enemies. Enter the battle after your main tank and try to focus squishy champions like AD carries and AP carries first. If they have more than few squishy champions, try to focus one that have huge CC availability like Malzahar. For more in deapth instructions about team fights read gameplay section.




Vulnerability to disables

Master Yi's vulnerability to CC is one of his biggest flaws. To be realistic, this flaw is very hard to be fixed via items, runes, spells and masteries. I try to counter this flaw by taking Quicksilver Sash and situational defensive items like Banshee's Veil.




Low HP Pool

Master Yi has pretty low HP base when it comes to Melee AD carries. At level 18, his basic HP is just under 2000. The best item IMO to counter this con is Frozen Mallet. Its good for you on defensive and offensive side, by granting you both massive health and AD + slow.


Abilities





____________________________________________________________________________



Double Strike

Master Yi strikes twice every 7th attack.

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.

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.


Summoner Spells





Flash

Teleports your champion toward your cursor's location.

One of best spells IMO. Its useful both in offensive and defensive tactics. You have been hopelessly ganked? Flash away. Enemies chasing you? Flash over the wall. Enemies got away with 50Hp? Flash to them and deal 1 more attack. I love this spell, even after the nerf in November 2011.



Smite

Deals 445-870 true damage (depending on champion level) to target enemy minion or pet.

This is obviously a must pick for junglers. Not only it helps you jungle faster than you could with any other spell, it also grants you amazing buff controls. I can't stress how important smite is, I personally have stolen Baron more than 10 times with Smite.



Ignite

Ignites target enemy unit, dealing 70-410 true damage (depending on champion level) over 5 seconds and reduces healing effects on the target for the duration.

This is another great spell for Master Yi. It deals a lot of damage and is great to finish off champions with this extra damage. Ignite is also useful because of 50% Healing reduction. With Ignite you can shut down enemies like Swain(**** on their healing capabilities) easily.



Exhausth

Exhausts target champion, reducing their Movement Speed by 40%, attack damage dealt by 70%, and ability and item damage dealt by 35% for 2.5 seconds.

This is great spell and like Flash and Ignite, works miracles both in offensive and defensive tactics. When chasing, this spell reduces enemies Movement Speed by 40% for 2.5 seconds, which makes it a great offensive tool. When using it defensively, this tool protects you by nerfing attacker's basic attack damage by 70% and item/ability damage by 35% for 2.5 seconds.



Cleanse

Removes all disables and summoner spell debuffs affecting your champion and lowers the duration of incoming disables by 65% for 3 seconds.

While I rarely use it, it can be still viable on Master Yi. This champion is extremely vulnerable to CC disables and if you do not intend on buying Quicksilver Sash, this spell is kind of must take. Since November 2011 it also removes Ignite, which is great.



Teleport

After casting for 4 seconds, teleports your champion to target allied minion, turret, or ward.

This spell is viable if your team has no pushers and they rely on you for pushing. When enemies are attacking your tower in group, just teleport to pushed lane and destroy towers quick. Hidden pushing is something Yi excels at.
