HELLO everyone and welcome to my jungle lee BUILD
First of all i have to say that you can solo top lee well too, but i find it lot of better to jungle with him as his ganks are devastating early levels and if played well you'r huge thread to your enemies early-mid game. :)

lee as a champion is so much fun! who would not like to play chuck norris ?:d

pros/cons

pros.
sick dmg early/mid game
with this build you can actually carry
gap closer
op if played right
can escape and troll so easy with (w)

Cons.
some might say his dmg drops late game?
maybe hard to master
thats all :D

when jungling i guess you wanna start at wraiths and red. Always remember to give blue to your ap mid! but dont give it if theres a troll pick.

buying douple dorans when first b is huge dmg boost, sustain etc.
But remember to buy boots 2. dont wanna run with 325 mvs..

in this build im picking exhaust instead of flash. Reason is simple: 1.ganks are better 2. you dont need flash..

Lee sin (w) ability, safe guard is the key for escaping. i recommend to use smart cast for faster moves! you can change this from key bindings.
FIRST thing you gonna wanna do is when base, always buy atleast 1 ward to your inventory.(wrigles is there for it 2)
when chased put ward for example over walls and safe guard to it!
when you are escaping in jungle dont be afraid to use your Q to jungle minions over walls and such. trolls your enemy hard,.;d

when really fed as lee is sometimes go: mercury threads->wrigles-> BLOODTHIRSTER

the dmg w this setup is really sick.. just your ult hits like a truck.

i think lee sins job is to q enemy ad/ap carry and shred 'em into pieces.
Lee sin not so good against tanky enemies :/

btw the reason i max (e)TEMPLEST/CRIPLE first, is that its AOE. its so much better on team fites early game. why max single target dmg close gap (Q), when you can pick AOE dmg/slow ? :)
