Master Yi Jungle GuideSo you'd like to be a bad ass jungler and later game carry? You've come to the right place friend, prepare to step into the wuju zone....
First and foremost, let's assume you're a level 30 summoner, if you aren't that's ok you can adapt this to your level.
MASTERIES:Since the new patch, I've tried many variations on my Yi Jungle build, but this is the combination that I've found works best, especially for carrying later in the game.
21/9/0
SOME PEOPLE will disagree with this and say the 20% increase to buff duration is critical during the early stage of jungling, however I find not having executioner is more crippling, and so is not having the 10 bonus gold per smite. I've found 21/0/9 is also doable to get that buff duration increase
RUNES:Marks - Armor Penetration
Quints - Armor Penetration
Seals - Dodge ( You can also use Armor if you'd like )
Glyphs - Magic Resistance per level
This will give you a huge bonus early game to damage output and tank killing power all throughout the game while improving your survivability.
Core Item Build:Item 1 - Wriggles Lantern
Every jungler needs one, this has to be the first item you build, life steal, ward, armour, damage and chance to do bonus damage to creeps

I love my berserkers greaves , but you can play with merc treads or tabi if you see a dire need for dodge and armor or mr and stun reduction
http://leagueoflegends.wikia.com/wiki/Berserker's_GreavesItem 3 - Youmuus Ghost blade
basically a copycat version of your ultimate, can be used in conjunction with your ultimate to go crazy, or use them one at a time so that you always have an escape or ability to kill.
Also gives armor pen, damage, critical strike and cooldown reduction
http://leagueoflegends.wikia.com/wiki/Youmuu's_GhostbladeItems 4 and 5 - Atmas and Warmogs or Atmogs for short
The main reason Yi isn't chosen much is if he gets stunned and/or focused, he dies so fast that it's irrelevant what his damage output is, enter Atmogs...Massive Health Armor and Damage gains from combining these 2 unlikely yi items. Also gives 18% critical strike

I recommend building either a banshees veil if they have mr or stuns, or a quiksilver sash.
If not you can make infinity edge, black cleaver, bloodthirster, frozen mallet etc etc... whichever 6th item you would like.
* Note, if the game goes long, and you are building up gold, sell your wriggles for a bloodthirster or starks, sell your boots for phantom dancer
Jungle Yi Pathing -
I've found the most efficient route is double golems with smite, wraiths, wolves, blue with smite then do golems again, wraiths to wolves, shop, red *Gank for whatever lane needs it* then golems wraiths wolves again
You can try something different if you want, sometimes a level 2 gank right after golems if you are purple can work if they dont have an escape
Thanks for reading
