Everyone knows the rumors about Master Yi, he is an easy autoattack based champ who makes one Pentakill after the other. Well, I don't deny that he makes a lot of Pentakills and
it's true that he is easy to play, but he is also hard to master. The timing on Alpha Strike and Meditate makes the difference between a bad and a good Yi player.

One of the main factors that I main him is simply because it's so much fun to play him. Atleast for me.

With this build I'm trying to remove the weakness of him being too squishy.
This build might look bad on your first view but after you tried it you are going to agree that this build deals just a stupid amount of dmg and oneshots an APC or ADC even as a tank in the later states of the game.

This build might look weird because you haven't seen a lot of tank Master Yi's or even none at all.
It just takes ~40 minutes to try it for yourself. (Or even less in a botgame)

This build simply works so well on him because the three items Skirmisher's Sabre - Bloodrazor, Guinsoo's Rageblade and
Blade of the Ruined King offer a hella lot of Attack Speed + his Ultimate Highlander which also gives him Attack Speed and a lot of Movement Speed. There is no enemy which can run away from you simply because your high Attack Speed refreshes the passive of Black Cleaver which adds another set of Movement Speed.
Guinsoo's Rageblade also has the effect that every Basic Attack triggers on-hit effects twice, which means that the passive of Skirmisher's Sabre - Bloodrazor, Guinsoo's Rageblade and Blade of the Ruined King also trigger twice.
Important to mention that Guinsoo's Rageblade deals Magic Damage and Skirmisher's Sabre - Bloodrazor and Blade of the Ruined King deal a percentage of the enemies HP.
Let's not forget about his E Wuju Style which can also trigger twice and add a painful amount of True Damage.

Here is a screenshot of some of my stats:


And some more for the case:



Screenshots from Guideusers:





Pros:

+ Very fast Jungle clear thanks to Alpha Strike
+ Very strong Midgame (which leads to a lot of surrenders]
+ Very hard to itemize against thanks to the True Damage from Wuju Style, the Magic Damage from
Guinsoo's Rageblade and the percentage Health damage from Skirmisher's Sabre - Bloodrazor and Blade of the Ruined King
+ Can catch people off-guard because of his high mobility
+ Needs 2 Basic Attacks to kill the Squishys.
+ Can dodge a lot of Spells with his Alpha Strike like Cease and Desist or Ace in the Hole
+ Meditate helps him to survive with gaining some resistances
+ Has very good cleanup
+ Can easily get away if caught

Cons

- Weak early
- No Crowd Control
- Weak in Teamfights
- Will get focused
- Difficult to use Alpha Strike and Meditate correctly.



I prefer E second because you gain a lot more damage from it.
The true damage with your passive and krug buff melts the Redbuff easily.
You need your W on lvl 3 because otherwise you prolly ain't gonna make a full clear of your jungle.



Passive: The passive is one of the main things that helps this build to work. Every 4th attack strikes doubled but only deals 50% of the damage. The 50% doesnt really matter because the true damage from your E Wuju Style is an On-Hit Effect, that means the damage of it isn't reduced. It's the same for Skirmisher's Sabre - Bloodrazor and Blade of the Ruined King.
It's also important to mention that after your first activation of your passive you only need 3 Auto-Attacks because the second strike from your passive counts towards it.
It's like: 1-2-3-4(1)-2-3-4(1)-...

Q: This is prolly the most important ability. It can hit up to 4 enemies, that means you will always hit every monster at a camp and it does a really high amount of damage to them.
In a fight it makes you untargetable and it helps you dodging tower shots and more or less dangerous abilities like Ace in the Hole, Requiem or Cease and Desist. It may take some time but after a few games you should feel improvement. You may keep in mind that it doesn't negate the damage from things like Ignite or Brand's passive Blaze.
Every Auto-Attack reduces its cooldown by 1 second and thanks to your passive Double Strike you get it even faster.

W: This skill allows you to heal up for a certain amount which is increased by your missing health. It also gives you 50-70% damage reduction. The downside is that it's easily interrupted by a stun, silence or a knockup/knockback. So you want to use it when your enemies have used all of their stuns etc..
But if you time it right you are easily able to turn around teamfights for example if your Q Alpha Strike is on cooldown and you need to survive some more seconds. It has often enabled me to be successfull in a 1v2 or 1v3. On max lvl you get as much dmg reduction as an Alistar in his ultimate Unbreakable Will.
I recommend you to max this 2nd if you join early teamfights.

E: Even tho the 10% extra ad from its passive is pretty nice, the true damage from his active is the thing that makes it so hard to itemize against him. It lasts 5 seconds, scales insanely with his total ad and also benefits from his passive Double Strike.
Remember that the passive is disabled as long as the ability is on cooldown, so don't waste it on towers since it doesnt deal true damage on them.

R: This ability is just insanely strong because it not only gives you a lot of attack speed and movement speed, it also makes you immune to all slows, that includes movement and attack apeed slows.
That as an ability would be already really strong but it also has the passive to reduce all your remaining cooldowns by 70% if you get an assist or a kill. Combined with your passive Double Strike and the passive of Alpha Strike you can use your Q after every kill.



Greater Quintessence of Attack Speed
I choose these because Master Yi scales very good with Attack Speed, for example his Passive Double Strike gets activated more often.
Some people suggest me to take Greater Quintessence of Movement Speed but personally I don't think it's necessary because he already has the highest Movement Speed.
I wouldn't recommend Greater Quintessence of Attack Damage because it slows your Jungling down for a decent amount and you lose more health because the Ancient Krug buff doesn't get activated that often.

Greater Mark of Attack Speed
It's pretty much the same as for the Quintessences.



Greater Seal of Scaling Health
These are the best in my opinion because in this meta are so many Armor Penetration items that Greater Seal of Armor doesnt really do that much.


Greater Glyph of Scaling Magic Resist
Since your build usually has no Magic Resist, you want to have a bit atleast.
And since you AFK farm the first couple of minutes the scaling ones are better than the flat.


Greater Glyph of Scaling Cooldown Reduction
This gives you a total of 10% CDR on level 18 which helps you clearing the Jungle faster and getting your abilities back up.
And since your Ult Highlander has the effect that a kill or assist reduces your Cooldowns by 70% it's also shorter.



Ferocity Tree







Fury : More attack speed
Double Edged Sword : Increase of your damage
Vampirism : More sustain
Bounty Hunter : Increase of your damage
Battering Blows : Increase of your damage
Fervor of Battle : Increase of your damage (Read my opinion in the patchnotes chapter)














Cunning Tree







Savagery : Makes your jungle clear faster
Assassin : Increase of your damage
Merciless : Increase of your damage
Dangerous Game : More sustain in teamfights
















Why do I prefer 18-12-0?

I went for 18 into the Ferocity Tree because Thunderlord's Decree is not comparable to Fervor of Battle because it only gives you a small burst and then it has a very long cooldown. You would most likely use it once in a battle and that's not much.


Ferocity






Cunning







Must have Summoner Spells:

Obviously. Duh.




Good:

It's almost impossible to play a perfect game, so Flash is a good Summoner Spell to undo your mistakes. For example to reposition in a teamfight if you did a bad engage.


This helps if you want to farm really quickly to get your items and stacks as fast as possible. It also offers a good way to flank the enemies. But it's not really useful if you are IN a teamfight.


OK:

I wouldn't judge you if I saw you playing with it, because it helps catching people offguard or helping an ally who is in danger and quite far away. But you have no chance to reposition fast in a fight.


I'd only recommend this if you play against another Jungler who is more of a duelist like Udyr or Shyvana. It's also a useful way to reduce the DMG of Assassins who'd oneshot you like Fizz.


This gives you more kill pressure in the early game. Also useful against champions like Dr. Mundo who have a high health regeneration spell.



BAD:

In my opinion only good on APC's or ADC's who can use the heal to survive heavy damage spells and the movespeed to run or kite. Not good for an offensive champ like Master Yi.


A bit more useful than heal but still a bad summoner for being offensive.





Blue Side: You really want to start at the Ancient Krug because his buff is very powerful. Thanks to it you stun monsters/minions with every 6th Auto-Attack and even less with your passive Double Strike. Compared to a Redbuff start you have more health after a full clear because the Redbuff just gives you a certain amount of health which is easily lost by just a few Auto-Attacks from monsters and the stun buff provides you from getting a LOT of hits by jungle creeps because it remains until you have beaten the Bluebuff. You'd also need a lot more time if you wanna do a fullclear, which you wanna do since you can buy your first upgrade Skirmisher's Sabre after it.


Red Side:
