Hi there! I'm Obvilion, a level 30 summoner from the North American server. I want to make this guide to help you, and this is no book of laws you must follow. Now that I've made it clear, let's talk about Lee Sin's overall performance, shall we?

Lee Sin is a Bruiser, who's job is to try to take out the enemy's AD Carry, or AP Carry. But, if the fight is in the other team's favor, Lee Sin has to try to CC Dragon's Rage Tempest the enemies away from his carries. He is more like an AD Caster, as he does not rely heavily on his auto attack, but more on his abilities Sonic Wave. He does a lot of damage early game and mid game, but slightly falls off late game. So to counter your weakness in late game, you must be a bit aggressive in the early game phase. If you are top, constantly harass, as you have Energy. And if you are a jungler Smite, gank the lanes where the enemies are most over-extended. Also, try to counter-jungle the enemy jungler to deny them experience.

Pros +Counter to all Stealth Teemo Akali Twitch
+Not countered by blind, he is an AD Caster
+Has very useful CC Dragon's Rage
+Good burst for a Bruiser


Cons -Bad Damage without Q
-After ulti is used Q won't do as much during quick bursts
-Easily kited after you miss your Q
-Costly items

Smite: This summoner spell is great for decreasing jungle time, securing buffs, stealing enemy buffs, etc. It is a good spell for jungling overall, but do not consider using this while laning, because you wont get much out of it.
Flash: This is an extremely useful spell for Lee Sin. You can use this to get out of a sticky situation, Flash through walls, catch up to enemies, etc. It's just a good spell to have overall. It can also help you position yourself to land your Resonating Strike.
Exhaust plus the mastery, Summoner's Wrath can be very deadly when you are in team fights, or even one on one! A great spell to use overall, whether to run from an enemy or to catch up to your fleeing opponent.
Ignite: This is a great spell to finish off fleeing enemies or dealing that extra damage in a 1 v 1. If that's not enough for you, it also deals true damage and applies grievous wounds on the enemy! So this summoner spell is extremely useful against fed AD Carries because their high damage causes them to have high lifesteal, and ignite cuts it in half.

Good Summoner Spells Ghost: If you don’t have Flash or prefer the use of Ghost, go ahead! It lets you catch up to enemies or escape, but CC can sure cancel it out.
Heal: This is a nice spell if you are new or uncomfortable with Lee Sin. It is actually a lot more useful than you expect. It has helped me turret dive and bait Heal many enemies into diving me under my tower!

OK Summoner Spells Cleanse: It’s a very hard summoner spell to use (timing is very important!) but it is very useful to remove slows, stuns, etc. But quick silver sash is a free cleanse, so I wouldn't recommend this.

Summoner Spells I do not Recommend : This is not very useful on Lee Sin, as when a hero uses Surge, the opposing team will often CC you to lock you down. Also you might be a target to kite around, and therefore wasting the duration of Surge.
Revive: The CD is too long.
Clarity: Lee Sin does not use Mana, but uses Energy instead so therefore this spell will not benefit you in any way.

: When activated, it shoots out a blue ball of sound and damages the enemy, revealing them, and when you cast the spell again you dash towards them and you kung fu kick their faces. This deals a lot of damage, and even more when your target has lower health (8% of their missing HP). One of the best spells in the game, it's perfect to finish people off and the base damage at level 1 is 100! It's great for when the enemy is running, but be careful not to hit minions, as it does not go through them. Also, it's a skill shot so aim carefully, but whenever you hit it on an almost dead enemy, it gives you satisfication 99% guarantee!

: The second ability of this skill is Iron Will, and it gives you armor, spell vamp, and lifesteal! The first cast gives a puny shield unless you build AP Lee Sin... which I do not recommend you do. But you can use safeguard to dash to a ally hero, minion, or even a ward! It's a great escaping tool, and I will explain it in further chapters

: This skill does not do much damage, it's best used on AD people like their AD Carry Ashe Vayne Miss Fortune. It slows the enemy, and it deducts their attack speed. Very useful on 1 v 1. Even better if you use it in the middle of the whole enemy team! So this skill is used for it's CC, not the damage.

I am still working on this guys, so if you see this message I will try to be done as fast as I can...
