Hello everyone!
After playing Lee Sin for a while i resolved to write a guide, because many players buy wrong items on him or play him in a wrong style
I know jungling without Smite is not for everyone, but this guide will show you, how to jungle succesfully without using Smite or recall at lvl 3
Enjoy it ;)

Pros:
-Amazing jungler
-Very nice ganker(provided that you land your Q skill)
-very strong early game
-One of the best anti-carries in game
-Can fulfill a lot of roles in your team(tank, offtank, dps, support)
-Very funny char, you will never be tired of playing him
-every skill can be used to chase or escape an enemy
-game changing ultimate

Cons:
-hard to learn
-need a lot of time to master him completely
-every time focussed in teamfights
-you have to master landing your Q skill, to gank succesfully

To be serious, this are my Warwick Jungling runes, but meanwhile I use them on every offtank jungler

9x Greater Marks of Alacricity
9x Greater Seals of Resilience
9x Greater Glyphs of Alacricity
9x Greater Quintessences of Resilience

+21% Attack Speed
+25 Armor

That Runes gives you enough Armor to survive early game jungling and Attack Speed to kill jungle creeps

Furthermor Armor runes + Cloth Armor + W = unbeatable in jungle

May you ask yourself why I took Archmage´s Savvy:
Deadliness is unnecessary on Lee Sin, you don´t need Crit Chance
Furthermore you don´t have to lvl Lethality
I hope the rest is self-explanatory, if not just ask me ;)

I start with Cloth Armor and 5 health pots, like every jungler
When I port back ill buy Madreds + Shoes
After gettin Wriggles and Mercury Treads i´ll rush Frozen Mallet for surviveability and stronger ganks(40% + 60% slow = no chance to escape)

The rest depends on enemy team: I prefer to get Atmas after Mallet, but if enemies AP carry is fed, buy Banshees

After finish this build, you should be a super strong offtank with 3000 hp, 150 armor & MR and insane damage

However if the game still goes on and you don´t know what to do with you money, change Wriggles Lantern against a stronger Item f.E Bloodthirster

1. Golems
2. Wraiths
3. Wolfes
4. Blue
5. Goolems/ Red / Port Back

Try out that build before you begin to downvote him, and tell he how it was
Furthermore I want to apologise that this build looks so ugly, but I´m not conversant with that Mobafire control system, I am going to update this build and add some chapters after I learned more about it ;)
