Lee Sin is a highly aggresive jungler from early to mid game, He can clear jungle camps quickly and make good ganks with his 2 gap closers along with his movement speed slow. He's good in 1 v 1 situations and skirmishes and is a good pick for any team comp.

Lee Sin can build a mix of tank and damage. There are some builds for pure tank and some just pure damage. Tank and damage is best and reason being is going full tank will mean you will fall off and not be too much of a threat to the enemy team. Going full damage glass cannon is just stupid. As Lee you are the initiator and should be starting fights for your team.

- Well You're Jungling. Why WOULDN'T you get this. Needed for securing baron blue etc.

- Used for both Aggressive and Defensive plays. Extremely useful at late game and in teamfights. Works well for Flash +

Always put pressure and make presence. Lee Sin is a monster early game with strong ganks and fast clears in the jungle. Never forget to counter jungle. 99% of the time you will beat the enemy Jungler if you don't miss your Your text to link here....

Your normal setup for ganks would beto something then use to follow up. You are also very squishy at this time in the game. So if you are ganking a tanky top (ie Renekton) and get counter ganked by their pantheon. This would normally mean death for you if you dont flash.

Now is the time to group, steal buffs and get that dragon.
By now you should be a little tanky and have maybe 2 of your core items.
Do not be afraid to engage fights. This is what your supposed to do. Kicking an enemy carry towards your team is probably the best thing you can do unless it is a really fed eve or something then you shouldnt kick that person towards your team. You are still very strong in mid game and should abuse your power. Never be afraid to counter jungle. Lee Sin can duel pretty much anyone in the game. Lee is also good at soloing the dragon once you have elder lizard. save your trinket for ward hopping over the wall if you get caught doing dragon. Get a pink and clear enemy vision of river or tell your support to use sweeping lens to clear for you.

Now this is where the game actually gets hard for you. By now you have to either go in ham for their carry or be a peeler for your carries. Vision control - At this point of the game. If your team is constantly fighting or fighting over baron, It could be worth getting a sightstone and upgrading to the vision totem trinket. NEVER FACECHECK I shouldn't even have to say this. Lee Sin has his Q for checking brushes. You can also use sightstone for ward hop and 'insec' kick a carry towards your team.

Don't be afraid to go in deep to kick them towards your team. It's the best thing you can do at this time of the game. Just don't go in ham. You will most likely have fallen off at this point.Once you have used all of your cooldowns and have nothing left your just a sitting duck and can get kited very easily. Make use of your abilities or you might just die by that fed Vayne if you don't.

Wardjump:- Use this technique to get closer to land an important Sonic Wave, escape over a wall, or to position yourself for Dragon's Rage. Tap the ward and Safeguard in quick succession.

"Insec": - - - - This is one of the most important combos you can pull off as Lee Sin. It allows him to pick off enemies while siegeing. You often want to do this to high priority enemy targets (such as the marksman), kicking them into your team.
