Ignore rating, entirely new build, wanted to restore my honor...lol...also, credit to Dyrus, used his build as a reference.

Summoner skills are extremely important in League of Legends and can be game changing. Master Yi is no exception to this, however, unlike some champions, Master Yi is extremely versatile in his use of summoner skills.

My Choices:
Exhaust
Strong CC, Works well with his ulti. Allows you to attack your target as if you're both standing still.

Smite
You're a jungler, so this is pretty much necessary, try to steal buffs should the opportunity arise, just don't die for the steal if you're not 100% and it's not baron.

Other Choices:
Ghost
You can't get much more mobility than this. With the ability to use both Ghost AND your ultimate, you should never have ANY TROUBLE getting where you need to go. This skill can make backdooring the easiest thing you've ever seen. Either using it to get there quickly if necessary, or using it to beat a hasty retreat in the opposite direction.

Heal
Better than before, but still not a good pick for Yi in the jungle really.

Revive
No.

Teleport
If you were laning it would be a decent pick. You can bring it if you wanna win off backdooring I suppose, but if it gets to that point, it's probably over anyway.

Clease
Your ultimate already acts as a cleanse more or less. Any REAL problems you have can be solved by a Quicksilver Sash. Cleanse can be a good choice if you are just learning Yi and finding yourself in sticky situations often.

Fortify
Really not used outside of gimmicky teams, and even still, you're not the champion for it anyway.

Clarity
No.

Ignite
You really don't need the extra killing power. The main use of this skill is if the enemy team has a Mundo. Otherwise, it's simply not that useful as you will auto attack them to death just as quickly once mid-late game rolls around.

Rally
No.

Clairvoyance
Save this for a support character, you have much better choices at your disposal.

Promote
Not really good for you.

Surge
Haven't tried it, though I could see it's uses in situations, I still don't think it's worth taking over another summoner spell.

More to Come when I get around to it.

Core Items

Boots:

Berserker Greaves
These boots are the best option to enhance your damage. You should get these anytime you don't have a real need to pick up Tabi's or Treads.

Ninja Tabi
These are for teams with multiple AD champs, such as Jungle GP, Tryn Top, Caitlyn bot.

Mercury Treads
These are for teams with lots of Crowd Control or AP.


Wriggles
Great free wards, lots of lifesteal so you can heal up in the jungle between ganks, and a little armor to keep you safe(r).


Youmuu's Ghostblade
The ultimate Yi item. Pop this with Wuju Style and your ulti to absolutely clean house, you might surprise yourself how much damage you do with it.

Situational Items

Path 1:
This is the path to use if you've gotten the core build and you do an okay amount of damage build you REALLY need that extra defense to stay alive in fights. Don't expect maximum damage output with this path, but you won't be so easy to kill anymore.

Warmog's Armor
Provides a lot of health for a strong defense that usually seems to build quickly.

Atma's Impaler
Great synergy with Warmogs, provides a good amount of damage, even when forced to build tanky with Warmogs.

Frozen Mallet
Worth a mention here, the health and damage stack well in this combo. Also provides a great slow to keep people in place longer.

Path 2:
This path is where you will really see the damage. The armor pen from Youmuu's and Last Whisper will blow your mind. Additionally, the crit, move speed, and attack speed provided from Phantom Dancer will make you an unbelievable killing force for a rather cheap investment. You can then take this path and build in a couple directions, either pick up an IE to boost your damage from PD, Bloodthirster for the sustain, go back to path 1 and pick up your atmogs, or pick up some straight defense like Banshee's, Force of Nature, or Guardian Angel.

Phantom Dancer
Everything Yi loves, crit, movespeed, attack speed. Absolutely amazing. I should probably point out that with Master Yi, since his Wuju Style provides him with an attack steroid, you can build movespeed and attack speed which will directly result in a strong damage increase due to more frequent procs of Wuju Style.

Last Whisper
The armor pen from Youmuu's in combination with Last Whisper will make you the ultimate shredding machine, just be aware that you're still squishy until you throw in some defense.

Filler Items

These Items are here for you to throw into your build at any point for some added survivability, damage, or utility. Worth a mention that it's generally not a good idea to rush these, build them bit by bit as you build your main path(s).

Banshee's Veil
Banshee's allows you a good deal of magic resistance to help counter some of the damage that Thornmail would deal to you, as well as making those annoying burst casters virtually useless. Additionally it will eat a stun for you, allowing you to get away much easier. Always a good choice for survivability if lifesteal or that warmogs just isn't getting it done for you.


Guardian Angel
This option can be great to increase your survivability, as well we allow you to "rambo" a little more if you find it necessary. It is also a good way to save yourself late game if you find your team consistently getting in bad positions that could result in losing the game.


Quicksilver Sash
A nice cheap item that provides a little magic resistance and more importantly, allows you to remove blinds and stuns, giving you the ability to finish off those characters that would simply just exhaust you and run away.


The Bloodthirster
Quite a bit of damage and quite a bit of lifestyle. Generally the number one choice for damage on Ranged Carries, and it can be good on you too. Just know that you don't NEED a BF Sword Item (IE, Bloodthirster, Black Cleaver) to do damage. Riot gave you that Attack Steroid (wuju style) for a reason. This is mainly for the purpose of healing in the jungle between ganks/team fights, as well as a strong heal when you're not being focused down and you can attack freely.

As soon as I get around to it.
