Welcome to my Master Yi Jungle Guide. It´s my first Guide in Moba, so I hope you like it.
I played a lot of Master Yi in the past time and searched for the best build you can use for him in Jungle.
Master Yi is a very fast jungler and ganker in any gamephase.
His skills allow him to do a easy and fast Jungle.
The most players build him very offensive with items like Phantom Dancer or Infinity Edge.
But I think he is way better with more Life and Armor and is more Usefull in Teamfights in late game.

Pros:

- Easy Jungle
- Easy Ganging
- Very Fast
- Much mobility
- Good counter Jungle
- Nice Ult

Cons:

- Bad against invincible Champs
- Good Ganking at lvl 6
- Needs much Gold

Summoners are very variable for Jungle Yi.
You have to combine you masteries / runes / starter items with your summoners.
If you go for Exhaust / Smite you could use Greater Quintessence of Movement Speedand Swiftness .
If you go for Ghost Greater Quintessence of Desolation is way better then Greater Quintessence of Movement Speed.
Anyway Ghost is a good escape spell in combination with Highlander. No Champ ist fast enough catching this Yi.
Also you have a ultimate made for ganking so Ghost could go nice to catch with a extrem movespeed and useing Alpha Strike to dodge stuns.

You start with Boots for much mobility in early game, good ganks and fast jungleing.
Health Potion are very important here. Try to use less then possible.
Next up you have to buy Longsword, Zempric Scepter and new Health Potion.
As you made a successful first or secound gank you can buy a Cloth Armor too.
As next Item finish your Wriggle's Lantern and buy your Avarice Blade for extra Gold.
Here you could start buying Oracle´s Elexir.
After this finish your boots and go for Trinity Force.
Buy Phages first for more life and damage and get Zeal for the next Item.
Now finish your Trinity Force and get the Youmuu's Ghostblade.

At this point the game could end soon.

So now you have to biuld usefull items.
My favorite is Guardian Angel. Its very good for Teamfights and gives you more options in playing much more aggressive.
An other way is more AD. So you could go for an Infinity Edge or as needed a Frozen Mallet.
As you go for the Infinity Edge build Phantom Dancer next. At these Biuld you are a pure Damagedealer and could die in Teamfights fast.
If you go for Frozen Mallet by an Atmas Impaler. With this build you also have much damage and you´ll be better in Teamfights.
Atmas Impaler and Warmog's Armor is also nice. It´s more tanky than the Frozen Mattelt but it could be very usefull.

I biuld the Guardian Angel so next up Item will be has to be choosen in checking the enemy team. As your enemy has a lot of armor go for Last Wisperer, as they got much Life go for Madred's Bloodrazor.

The point is to build whats good for the Team, not only for yourself.

At Least you can exchange the Wriggle's Lantern with a Bloodthirster.

The Runes are important for the Jungle itself.
Without any Greater Seal of Armor there is no chance to start with Boots so you have to use Vamperic Scepter or Cloth Armor.
I took Mark of Desolation, Greater Seal of Armor , Greater Glyph of Scaling Magic Resistand Greater Quintessence of Desolation.
You can also use Greater Quintessence of Movement Speed for Yi. But i think its unnessesary as long as you start with boots or take Ghost as summoner spell.

Master Yi is a extrem fast Jungler with great spells for ganking and jungleing easy and great.

I generally start at the Wulfscamp, its very easy to get them without loosing much life by using Q on it and get a bit support by teammates. So next up is Blue Buff. Yi really needs the first Blue to jungle fast and gank much earlier than other junglers like Skarner or Alistar, also you have better cooldowns for useing Wujustyle at every Camp. So you can gank very early with lvl 3 or 4 (top lvl 3, mid lvl 4 as purple/ bot lvl 3, mid lvl 4 blue).

The 3 first ganks are very important for the team. If you see a lane is pushed much so gank instandly there. You as jungler has to help lanes that needs your help.
Ganking mid is very hard. The lane isnt as big as the other 2 so you have to be very fast. A stun there , like Vaiger or Sion are great to gank. Make sure your team has noticed you will gank soon. Make sure you pinged and wrote in teamchat. Good teamwork is the way of wining a game.

Bot lane is only a good gank as you get there while enemy carry and support starts a fight bot. In this sitiuation you can gank very easy. Most players are focused at this moment on killing the enemy, so your job is to gank fast and surprise your enemys in a bad way.

Counter Jungle your enemy is important to. After you saw him ganking a lane start to kill his wraiths or Wulfs and ward his Buffs. Disturb your enemys jungler costs him much time and exp.
He will start to gank more often, wards his jungle and will start counter jungle you!
So what you gonna do against this?
1. Ward Buffs
2. Buy orcale
3. Let your lanes do Golems or wraiths


As you finished your Lantern never use smite on Buffs or Golems. You have enough damage to do them very fast. So hold smite for Drage or Baron. It is an very important spell for these two.
Also in stealing them.

As you finished Ghostblade, you are an unstopable ganker. If you activate Ghost, Ult and Ghostblade you are so fast that there is no escape. Start your gank with Q so you can not be focused with a stun something like that.

As you play against a Akali in mid you have to by oracle against her field. As she use it your Ult will be useless so you have to see her.

All in All Yi is really an easy and nice Jungler for everybody. You can use him as your Top lane is tank or you got an good offtank top and Alistar support. I really like him in Jungle and he is very good in it. Its sad that so much players go for and Yi Ap mid or top so often.
He is well to play and easy to start your own experience in jungle in LoL.

So thanks for comments and rates. Hope you like it and seeya in Jungle!
