"Force is meaningless without skill!"
~ Lee Sin

This guide will not hold you hand and tell you how to play as Lee Sin, it will simply give the runes/masteries/items that I use and some helpful tips, tricks, and knowhow for him.

4/3/2011: Build published

• Test the build a lot more
• Get some video of me playing Lee Sin
• Add the Tips, Tricks, and Knowhow section

• Greater Mark of Desolation x9 to increase all of your damage
• Greater Seal of Armor x9 for extra armor
• Greater Glyph of Scaling Magic Resist x9 for extra magic resist (I go with per level instead of flat because most of the time you don't need to worry much about magic resist till the point where the per level ones will be about even or even above the flat ones.)
• Greater Quintessence of Health x3 for extra health

If you wanted to be more damage then you could probably take armor pen quints, I prefer the extra health though.

22/6/2 Pretty much the same that Phreak said, from what I've tried this works out the best.

Offense

• Deadliness - extra crit chance, pretty nice
• Cripple - improves your Exhaust to reduce the magic resist and armor and increase the duration, very nice
• Sorcery - an extra 3% CDR, pretty nice
• Alacrity - an extra 4% attack speed, pretty nice
• Archaic Knowledge - an extra 15% magic pen, only okay since you don't do much magic damage
• Sunder - ignore 6 of the enemy's armor, awesome
• Offensive Mastery - an extra 4 damage to minions, pretty nice
• Brute Force - an extra 3 attack damage, very nice
• Havoc - increased base damage by 5%, pretty nice

Defense

• Resistance - an extra 6 magic resist, very nice
• Hardiness - an extra 6 armor, very nice

Utility

• Good Hands - an extra 3.33% off of time spent dead (could be a game saver), very nice
• Haste - increased effect on Ghost, very nice

Unlike most of my builds, this build is hardly at all situational.

Core Items

The core items are as follows (in order of importance):

• Frozen Mallet
• Atma's Impaler
• Mercury's Treads
• Wriggle's Lantern
• Hexdrinker
• Youmuu's Ghostblade

Most games I barely get to Atma's (see the purchase order at top for which order to actually get the items in).

There are a few exceptions to this build:
IF:

• The enemy team is ALL attack damage
  • Switch out Merc Treads for Ninja Tabi
  • Switch out Hexdrinker for something more like Thornmail
• Your team needs a tank or tankier person
  • Switch out Wriggle's for a tankier item ( Force of Nature vs. all Magic Damage, Thornmail vs. all Attack Damage, Guardian Angel vs. half and half)
  • Get Randuin's Omen instead of Youmuu's Ghostblade
• You are about to lose
  • Sell all of you items and buy 6 Doran's Rings and use that as your excuse for losing (not really)

Priority and sequence are the same as Phreak's and is what I have found to work best:

Priority

• 1 Dragon's Rage
• 2 Sonic Wave / Resonating Strike
• 3 Safeguard / Iron Will
• 4 Tempest / Cripple

What to get and when

• 1 Sonic Wave / Resonating Strike
• 2 Safeguard / Iron Will
• 3 Tempest / Cripple
• 4 Sonic Wave / Resonating Strike
• 5 Sonic Wave / Resonating Strike
• 6 Dragon's Rage
• 7 Sonic Wave / Resonating Strike
• 8 Safeguard / Iron Will
• 9 Sonic Wave / Resonating Strike
• 10[Safeguard / Iron Will[]]
• 11 Dragon's Rage
• 12 Safeguard / Iron Will
• 13 Safeguard / Iron Will
• 14 Tempest / Cripple
• 15 Tempest / Cripple
• 16 Dragon's Rage
• 17 Tempest / Cripple
• 18 Tempest / Cripple

Exception:

• Your team needs a tank or tankier person
  • Get 1 point in Sonic Wave / Resonating Strike then prioritize Safeguard / Iron Will for your first to rank 5 and then Tempest / Cripple for you second to rank 5.

I go with Exhaust and Ghost for my summoner spells.

Possible Alternatives

• Ignite Why not try to get that kill (I prefer to take Exhaust over Ignite a LOT more on most champs)
• Smite If you are gonna jungle you NEED this summoner spell (good luck if you use this build to jungle though, never tried it)
• Teleport I find myself mostly using Ghost to get back to lane ASAP, could always take Teleport and get back even faster

Avoid these

• Clairvoyance Let the support champs use it, you really don't need to know, you can face check then dash out if there is danger
• Clarity Just like a Vlad/Morde/many other manaless champs taking it (Lawl-ish)
• Cleanse Why run, you can just kick 'em away or dash out to an ally (plus you ARE incredibly tanky)
• Flash You already have 2 dashes, why get another with a MUCH larger cool down?
• Fortify Meh, a nice spell, just not really for me and most other people
• Heal Meh, mostly used at early summoner levels when you don't have runes/masteries to compensate
• Rally WHY DOES IT EXIST!?!?! (if someone know send me a message, I'm clueless)
• Revive Only good about 0.1%, unless you're trolling, but then you wouldn't even look up a guide

This build hasn't been tested a whole lot but what I have done has worked out pretty good, you are very tanky and do a lot of damage.
