Hello there reader, this is my lee sin build. Your obviously here to learn more about playing the champion Lee Sin, the blind monk. I'm making this build because i've recently been dominating ranked matches over and over again and thought i'd share this with you.

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.

PRO'S................................CON'S
Nice damage..................... Sorta falls off late game...... if you let there be a late game
Good survivability.............. can be shut down
Great ganking................... Takes SKILL (if you want right click to win GTFO)
Easy Jungle

Pretty standard runes:http://www.mobafire.com/league-of-legends/rune-page-planner#&rune=356:9-262:9-263:9-360:3 Greater Mark of Attack Damage instead of Greater Mark of Desolation is not too unusual i just find it more effective when ganking and jungling in general. As for Greater Seal of Armor they're pretty standard while taking Greater Glyph of Magic Resist to maximize my tankyness early so if you ever have to cover a lane against an ap char you won't be squishy, also this build does not have a lot of MR so the extra MR is nice. Finally taking Greater Quintessence of Attack Damage to further aid my damage.

I believe on another guide someone said that ArPen does more late game than 10 ad? well my friend the trick is to make sure there IS NO LATE GAME.

My masteries are fairly standard and self-explainable but for those who want to know why ill shortly tell you. Standard attack damage builds take 21 points in the offensive (red) tree, and varies between 9 in the defensive (blue) tree and 9 in the utility (green) tree

Wriggle's Lantern standard jungling item, awesome for early game and always my first pick.

Mercury's Treads good boots for tanky/dps especially because this build doesn't have a lot of MR.

Trinity Force Another awesome item, the sheer number of different stats you get makes it great for nearly every ad character. That's without even mentioning the amazing passive which you can mouse over to find out its greatness :D

Atma's Impaler Now we start getting tanky, the impaler synergizes perfectly with the next two items.

Frozen Mallet the passive slow along with the tanky health bonus is great AND it adds ad from not only the item but the passive on your Atma's.

Warmog's Armor Completing the coveted Fratmogs, Warmogs armor is the item that gives the most hp in the game. If there are those who believe that the stacks are a problem and you should get it earlier i only have one thing to say: I have never ONCE gotten the warmogs because the game was over.

Your jungle route will consist of Wolves -> Wraiths -> Red Buff (lizard Elder) -> Golems -> Gank. If you are purple (Which is actually preferred in my opinion for jungling) gank top, If you are blue gank mid (unless there's an obvious opportunity).

REMEMBER:
you are not a one man team, tell your team what your doing, ping the lane, tell them to let them push etc.... COMMUNICATION IS KEY

Also remember that if the enemy team has no jungler or the jungler leaves their buffs are open to you. (beware warded ganks from other team)

Never forget to use your passive, that means you use a skill, hit the creep twice then use it again. This saves time, gives you life and will ultimately make your life easier.WOLVES FIRSTTHEN WRAITHS THEN RED BUFF (remember to use smite on the big guy)GOLEMS FOR THAT LVL 3

Tempest / Cripple is the best jungling start because it does AoE damage as well as reducing the amount of damage you take from creeps. At level 2 I take 1 point in Iron will / Safeguard to sustain during red. After this max Sonic Wave / Resonating Strike as soon as you can.(but make sure you take your Dragon's Rage at lvl 6 obviously) After your Q is maxed you want to put points in Tempest to maximize burst damage output. Then finally maxing safeguard at lvl 18. (I'll put it ONE more time in case your lazy and skipped to here, PUT POINTS IN YOU ULT WHEN YOU CAN A.K.A. R-Q-E-W IMPORTANCE.)

For ganks you'll always want to Sonic Wave / Resonating Strike in ( Iron Will / Safeguard sometimes works if they are over extended) and MAKE SURE YOU LAND THAT *****, if you dont the gank has already nearly failed. After you land the Sonic Wave / Resonating Strike, hit it again to dash to the hit target. IMMEDIATELY spam that Tempest / Cripple to slow them substantially decrease their run speed. If required you can use Flash and Dragon's Rage to knock them back. So in essence :

Sonic Wave / Resonating Strike -> Tempest / Cripple -> (optional) Flash -> Dragon's Rage

This has it's own section just because of the infinite applications of this skill. Disrupt ult's ,escaping , chasing , ganking etc..... the list goes on.

(Will be posting screenshots within the next few days about appropriate times for ulting)

All in all Lee Sin is one of the most over powered junglers in the game and if you play him correctly you can solo carry a team like the boss you know you are. GL HF and send me screenies if you want me to post them. (i'll post mine soon)
