Hey guys LALakersFan here and yes, this is my first guide so don't harass me on what i did wrong on the guide because i know it's not perfect but hey, i'm trying my best :)

You should start off with boots and 3 health pots as most top laners do. You could start with a cloth armor and 5 health pots if you're against champions with heavy poke such as gangplank with his parrrley or if you think you will have a lot of trouble surviving in lane against whoever you are vs. at top. But i would much prefer if you would start with boots and 3 health pots.

Your next item is wriggle's lantern. Why you ask? It gives you that great farming tool and lifesteal and free wards for just 1600 gold! You can also use the wards over walls to dash to with your safeguard for emergencies.

Phage is next because it's one of Lee Sin's main items (you could build it to a trinity force or a frozen mallet, get frozen mallet for a tankier build and triforce for extra utility.)

You COULD buy an aegis of a legion if your team is having trouble in fights and/or if you're having trouble vs. an AD and AP team mixed. Pick up a maw of malmortius if they have good AP casters that bug the **** out of you and that shield to stop them from finishing you off.

Atmogs (warmogs + atma) is great for Lee Sin because it gives you great sustain and there will be no way adc will kill you now.

Your last item should be a bloodthirster (replace wriggle's lantern with bloodthirster) mainly because it gives you that great ad and a good amount of lifesteal (if you farm well.)

I know, i say "because" too much :P

I recommend flash and ignite for Lee Sin. Flash is a great way to get out of sticky situations and go over walls whilst ignite is to finish enemys off in case they get away.

You could take ghost if you are jungling for better ganks.

Well, there you go :) my first guide. To be honest, i did not know what i was doing o.O Thanks for visiting! Oh and also Lee Sin is my favorite champion and that's why i did this guide!
