So,Hi everybody this is my first build ever so please be patient with me :).I ve tried to make this build because i wasnt satisfied with others here this one fits my playstyle so i hope it wil fit to yours as well :) And sorry for my terrible English :P

So as you can see our runes are simply forced to Armor Penetration + attack speed , if you wana be more tanky pick up some health quints but i prefer penetration because Lee sin is amazing assasin from the start of the game so these will help you own your enemies much more

Masteries are quite different than someone would expect but it fits me well like this because you have some HP + boosted penetration but its optionable if you prefer other summoner spells then i do just change it but you should always keep up that penetration from attack its really important.

Well,now comes the most important part,i was thinking about combination of items which i should pickup first survival or DPS you know ... , I decided that lee sin rly need that penetration his skills have great potential but honestly dont deal big dmg when enemy beggins to stack armor so i come up with items such as Last Whisper and Black Cleaver . Of course when you see that enemy team is full of squishies grab Infity or something like that , I guess that when you re reading this you are like hey so whats the CORE of build it is so chaotic well i prefer these kinds of builds because playstyle of every player is unique so you can little bit tune this build for yourself i just give you some tips (hopefully helpful tips :)

Ok,So Skill Sequence is most important thing and also most difficult thing to master on Lee , always remember that your Ulti is not just great dmg dealer but it is very funny to flash behind someone and kick them under your tower than sonic wawe + tempes with criple maybe you can add that exhaust , if you do this be sure that your enemy will go down :D ,anyway when you re on lane dont be afraid of harrasing with Sonic Wave + Tempest you have great potential to make that FB :) . Next very usefull combo is Sonic Wave + Safeguard i m sure you know what i am talking about , and last thing that i realy need to mention MAKE A FULL USE OF YOUR PASSIVE BECAUSE IT OWNS

So thats all i wanna say please write also your tips i m sure you have some to share , I would be happy if you ll write some critics . See ya in the game :) Bye.
