very first guide created for lee sin, its very interesting take, it focus' on putting out decent dmg, while still being able to take dmg, and stay in the fight long enough to do anything at all

PROs : very good at closing caps, if you can land a skillshot.
amazing at picking people off or killstealing if you can time properly
built with an escape and anti death button
slows aoe
multi knock up cc'er
built in lifesteal/spellvamp
decent farmer

Cons : doesnt seem to put out as much dmg as other dps characters.
if you cant land skillshot for Q, you wont do as much dmg
ult easy to use, but hard to master
all around a very hard champion to master

The build focus on not being as squishy to the enemies, and still dealing a fairly decent amount of dmg to the enemy champions.
i played lee sin full dmg and i end up dieing a tone of times, without the amount of dps as someone such as nocturne or yi, thus i play him more tanky

pretty self explanatory, only thing i can think of changing is ghost for flash. that will give you more immediate exit or entrance of a fight, encounter. other then that i'd always take exhuast because it allows you to take close to 0 dmg and stack that life steal back up in the middle of a 1v1. it also helps for escaping, charging, ect.

Skillz........ all about the skillz. Q by far does the MOST dmg of all the spells So for that reason i POWER LVL it till you hit 9. get safegaurd at lvl 2, and max it 2nd. get tempest at lvl 4 max it third. i find that tempest doesnt do as much dmg as i was hoping, it needs a small buff, but the slow is enough to allow a point into it at lvl 4. it also helps with the passive and allows for a longer, more sustain dmg, rotation.
