Welcome to my guide for wee sin the guy that don't give a FUCK!
This was meant to be a guide for my friends that don't really know how to jungle but like to play lee sin and want to learn how to jungle.

I chose these runes and masteries to be a general pick for lee, but depending on how good you think you are, and how you like to play, you could always change the marks to ad/lvl and make your masteries to 21/9/0 and have more of a damage based setup. I feel lee has enough dmg with the items that i suggested so you can go with the more tanky set up and the runes are just to have an easy to use set up for most ad junglers.

As before this is my preference on his abilities, if you want to have more dmg then max E over W, but i feel his Q has a low enough cd that i can rely on it for dmg, also the sheild and armor that you get from his W are too good. Also starting with his E for jungleing is best because it ups your dmg, and lovers their dmg (them i mean red because thats where i start and its good for killing wraiths too).

this is pretty standard, if you think you can get in and out easily enough you can take instead of flash but flash is just too good with 2 jumps already.

This build is intended to make you very tanky while still having good dmg. now if you feel confident enough and have enough help from your team off the leash, then you can start with or if you want to be a little safer and be able to get wriggles faster, start with its up to you, also take into mind what masteries you are using.

Now for mid game i left it simple because those 3 items are the core of my mid game, but if you feel you need to get something else improvise, but this makes you decently tanky, gives good sustain, and decent dmg.

Late game i think lee should be really tanky so that he can distract the enemy team away from your carry and onto you so that you dont kill their carry, unfortunitly you normally still kill the carry. but if you feel you need more dmg then i would recommend and over and , but makes feel more worth while. either way you should end up really tanky and still have good dmg. and the reason for always keeping is to always have at least 1 ward on you so that you can either ward stuff for your team or use it as an escape with your W.

now you can start where ever as lee, but i start wraiths, then red, then golems, then wraiths, wolves, gank/or give blue away depending on how low you are on hp, as always there are exceptions to this, sometimes i gank between stuff if i see an opening or i see their jungler ganking nearby. but ALWAYS check your smite dmg to make sure you dont mess it up, because missing a smite loses games. also lee is very good at stealing baron and dragon with his Q combined with smite.

stick to their carry or keep your team alive it doesnt matter lee does both at the same time no problem haha

have fun get good at jungling and make people rage :D by the way lee is pretty good at counter jungling so thats always an option.
