As a young teen, Lee Sin was intent on becoming a summoner. His will and dedication were unmatched by any of his peers, and his skill drew the attention of Reginald Ashram, the League's High Councilor at the time. While studying at the Arcanum Majoris, Lee Sin became frustrated with instruction paced for the other students. He spent his free time researching the nuances of summoning in hopes of graduating sooner. He made amazing advances in his arcane studies, surpassing all other students. By all indications, he would have become one of the League's greatest summoners were it not for one terrible mistake. Too impatient, he attempted to test his ability by summoning a beast from the Plague Jungles. What he summoned instead was a young boy, but not in one piece. He barely had time to look the boy in what was once his face before the jumbled human mass fell lifeless to the floor. A League investigation later revealed that the boy's entire village was obliterated by feedback from the ritual.
Lee Sin's talents were so promising that the League was willing to overlook the incident, but he could never forgive himself. He left the Institute and journeyed to the Shojin Monastery for eternal repentance, swearing never to practice magic again. Years later, hoping to atone for his crime with martyrdom, he set himself ablaze as a protest of the Noxian occupation of Ionia. He remained alive in this state, enduring searing agony for weeks. His actions paved the way for a League match wherein Ionia prevailed, but by the time he was doused, his eyes had been burned completely from their sockets. Hailed as a savior, he was reborn, and his will to act invigorated. He joined the League of Legends to continue his atonement with sweat and blood, a true monk's only possessions.

Wriggles Lanturn is the first "full build item" i bought because its very good in jungel and you got and ward for free (thats real good i think) ^^

Trinity Forse, Warmogs Armor and Mercues Treads is obvious according to me the best for Lee Sin. He gest alot of health and some damage. Another good item that i really like to have in a Lee Sin build is Atmas Impaler, The reason is that you get some more Armor thats good but its not the main reason. The main reason its that Atmas gives you 2% of your maximum healt in attack damage (Atmas Impaler works also good with Frozen Mallet).

The reason that I have been both a Bloodthirster and a Infinity Edge as my last item is that its depend on the game and the person that play Lee Sin.

Smite and Exhaust according to me the VERY best.

Smite: Awesome in jungel and with the mastery Summoners Resolve you gain 10 bonus gold on use.

Exhaust: Exhaust its very useful when you play Lee Sin bacause when you meet for example a Miss Forune that have great movment speed you just have to use your "Q" to jump at her kick her back with your ult ("R") and then use exhaust so shes cant escape so easy.

I have been playing Lee SIn just for a wile so its not a "pro" guid but i hope everybody have benefits whit it and Iknow that my english aint so good but i hope that every body understand.
