Hello, past 2 months I started playing jungle Yi, and he's very good. I want you to rate, give me tips or help you. Enjoy.

ALERT, THIS GUIDE GOT VERY BAD GRAMMAR

Why jungle ineast of lane Yi?

Because, he can play whatever you want. An Off-Tank (like my build) or a full-carry. His place is in the jungle, he can gank pretty well with Red-Buff/ Frozen Mallet, and he's faster and pretty easy to jungle and play.

Smite Duh, obvious, it's Jungle Yi!

Ghost Well, Yi = Speed, I like it. Help me running, chasing.

Other options

Exhaust It's cool when ganking and cut power.

Flash OP, can go to walls, but I prefer Ghost.

Cleanse Good against CCs, never tried it. Seems interesting.

Teleport Help you protecting turrets, but let the tank got it.

Surge Humm, good attack speed and can do harass with Q, but I don't like unless you go AP or Hybrid.

Promote Eerm, don't like it. If I use it's only for good pushers (Heimerdinger op)

Heal Clarity Revive Don't like it, don't use.

Ignite Meh...

Mercury's Treads IMO, this item is a must for junglers, off-tanks and tanks.

Wriggles Lantern This is a must to jungle, passive made you jungle easy, lifesteal and armor and attack damage.

Youmuu's Ghostblade This is the core item for Master Yi. Armor Pen is very good, CDR don't hurt you and active give you speed and attack speed, that combines with Highlander

Warmog's Armor I really like the atmogs strategy. He can be tanky with this item, that give you over 1000 HP and regeneration, with Atma's Impaler give you a good portion of Attack Damage.

Atma's Impaler Armor made you more durable, crit is also good and the passive made Warmog give you a really good AD.

Wit's End 90% of times I do atmogs, I buy this item. Attack Speed and 50 Magic Resist is very good, and 42 magic damage on-hit.

Alternatives

Frozen Mallet Slow is very good, HP and attack damage. Good alternative to Warmog.

Infinity Edge Really good Attack Damage, crit and crit damage, it's good if you're doing carry or crit.

Bloodthirster You can use this instead of Wriggles Lantern, mid/late game, and 40 creep kills give you 40 more attack damage, is very good.

Phantom Dancer More speed, crit and attack speed. It's a good item, combine with ultimate.

Madred's Bloodrazor If they're stacking armor and HP, use this instead of Wit's End. This go turn them down with the passive, attack speed and armor/ad is good too.

Trinity Force This give all he need, slow, HP, attack damage, mana, sheen and attackspeed/movement/crit

Last Whisper Good AD and tons of armor pen, this is very good when you got Bloodrazor and ghostblade

Quicksilver Sash Good when facing hard CCs like Mordekaiser, Warwick, Malzahar...

I don't try with jungle nerf, but I do:

Mini-Golems > Wraiths > Wolfs > Back > Blue > Gank top > Gank Mid > Red

When ganking, I do Q + E activo and hit the target. It's easy with frozen mallet or red-buff.

Focus who do more damage, then AD Carry, then mage, then support.

I do tanky Yi, so I start the fight. Always Q, active E, ult + Ghostblade, do an ace.

Pros:
Very fast jungle
Gank easy
Tons of damage
High speed
Excellent tank

Cons:
Go down with hard CC
Very weak early game
Easly counter-jungled

Fiddlesticks Can jungle really fast and take my buffs, and fear + drain can get me down, especially early game.

Nunu & Willump OP Blood Boil in carrys, can jungle fast with Q and got very good ratios.

Udyr He jungle where he plases, and it's one of the best counter-gankers.

Rammus Dat taunt...

I hope you enjoy the guide. Test with other items, post if you got tips or questions and have a great day.
