Hi Guys this is a guide on my favorite Champion, in this guide i will show u how to Jungle as offtank lee sin :D enjoy.

Pros
-Very good Ganking Capability with Sonic Wave / Resonating Strike
-Good Damage Early game
- Dragon's Rage can finish off and/or isolate Champtions
-He's Blind, and still kicks ***.

Cons
-Late game Damage may slow down and become less
-Requires much still to play, land and position Sonic Wave / Resonating Strike and Dragon's Rage
-A little quish early game
-He doesn't kick players off the map

For Glyphs i Take extra physical damage for high damage early game.
For Seals i take Greater Seal of Fortitude For extra sustain in jungle.
Greater Mark of Desolation will help u much becouse u need this armor pen for your ganks.
For quins i take Greater Quintessence of Desolation and Greater Quintessence of Resilience for sustain and even More Armor pen all love armor pen.

Basic masteries 21/9/0 for sustain and damage. not so much to write about.

The funniest part :D. Start out with vamp scepter build it to a Wriggles lantern then merc treads ( if they have much CC's ) if they dont have much CC's go for ionian boots of lucidity. Then go for Frozen mallet for the slow and Health Then Warmogs for even more health, After warmogs you should get Atmas impaler for the damage given from your health then Banshees veil for health and SpellShield.

BOOTS !
one of the most needed things in the game.
This is realy important a question that much people ask them self is Witch boots will i get here it is u want u get merc treads if they much stuns if they dont have much stuns u can get ionian boots of lucidity.

Summoner Spells

I Take Flash and Smite for my summoner skills

Flash I take flash for its countless escaping and chasing capabilities. If you can't catch up to an enemy, then flash then Sonic Wave / Resonating Strike to them. Flash has saved me many times fro m death, but be warned, sometimes it might malfunction and you can end up flashing in place.

Smite I take smite for obvious reasons, Jungling. You can use this ability to smite buffs to make them much weaker for you to kill at early levels, and it might help you steal enemy buffs by running in and smiting a buff/ dragon/baaron etc. If you're not in the Jungle and get out to lane for a but, you can smite cannon minions for extra gold.

Optional Spells
Exhaust exhaust can me substituted for flash, It has numerous uses such as evening out a 1v1, or slowing enemies allowing you to catch up. Personally, I prefer flash, but Exhaust is also a Viable choice.

Cleanse Cleanse can be useful for escaping ganks, or if your enemy team has a lot of CC ( such as lux's Light Binding of Morgana's Dark Binding. It can be a substitute for flash for it's flexible capabilities

Ghost Ghost can be used to catch up, or escape from enemies. Ghost can be substituted with flash. Its a mattter of personal choice, so if you like ghost better than flash then take it!

The jungle route Wolfs > Wraiths > Golems (Smite) > Wolfs > Wraiths > Lizard elder (Red buff) > golems > Gank > BTB > wolfs > Ancient golem buff (give it away if some1 is mana thirsty) Gank beetween these sections if u want.

I hope you find lee sin a fun and enjoyable champion to play, and I hope you enjoy him as much as I do :)
