A good LeBlanc jungler knows how to start a game even since he join the lobby. Many players rush their playing choice in the first seconds, calling their role repeatly untlil the whole team knows he/she will play that role. You won't do this cause you are jungler LeBlanc.

First of all you need to whait for another player to call the jungling role, THEN (but only after him) you will call the same jungler role and lock LeBlanc.

For a good Jungler LeBlanc patience is the most important virtue, so don't be upset when someone will leave the lobby kicking you back in the queue. Just repeat this process few times until the game can finally start.

At this point of the guide you may ask "but why end game's build is so strange? and why the skills order stops at level 14?"

That's a good question, i will answer it later, for now just think about the beginning.
When the game starts probablly you will be flamed by your jungler or even your whole team, that's not a problem and you don't need to answer those flames. As the game starts go for the Cloth Armor, some potions and a ward.

Place the ward in front of your mid's tower so the mid laner can start flaming you (if he has not already started).

Gawd, i forgot how to explain masteries, runes and summoner spells

Well Masteries and runes are not important for this role, just take one that can fit your play style and that's good, but summoner spells are very important for the build to work.
First of all you need to avoid everything that could help you killing other players/minions/golem/everythingthatcanbekilled.
Avoid taking ignite, avoid "*** saving" skills like ghost or flash.

The Beginning

After buying your first items, go for the red lizard and ask for a pull.
Now your team would simply refuse to pull, in this case read Chapter 4.
If your team pulls red lizard start attacking him and whait.
You will probably die but that's not a problem, just blame whoever pulled the lizard, saying that it's his fault if you died.


Mid Game

There's a simple thing you have to remember to play this build correctly.. never.. never.. NEVER GANK ANY LANE.
Ganking is the jungler's job, but you are not a simple jungler, you are LeBlanc jungler.
If your team starts flaming you for your missing ganks, just remember them how n00b they are and keep on getting killed by jungle monsters.
Start ganking the other lanes ONLY and i will repeat ONLY under enemy's tower

BE CAREFUL
Make sure the enemy WILL kill you and your allies WON'T kill the enemy or everything will be f****d up!.

Just go on playing this way and everything will be alright, whait for your team to start heavy flaming, asking reports etc. then you can start your core build: all boots.

When you will hit level 14 your build and your job are finished. Just ask the other team to report your n00b team which is refusing to help you jungling and keep flaming you.

READ CAREFULLY

now it comes probably the most important part of the guide, every player at this point of the game would just leave or feeding the enemy.

You are jungler LeBlanc, you can't end your journey this way.

The best way of ending the game is saying "gg noobs" or "report theze n00bs" and ONLY THEN leave the game.

1- Remember to use your W correctly, for example to fast travel under the enemy's tower or chasing a full health fed AD Carry while your health is <20%

2- Your clone is very important, always try to save him over you, for example you can move him under your tower while you sacrifice yourself for it's safety.


Additional uses for your passive

-if your ally is dodging enemy's varus ultimate for few tiles, just move your clone to intercept his ulti so it can snare him and than your ally.
-your clone's safety is very important, always send him in the range of janna's Ultimate.

Chatting

-always remember your team how pr0 you are, tell them you learned all pr0 players playstyle like Xpeke, HotshotGG or Ocelote.

-Tell your team that you are playing with your smurf account, your REAL one is something like 1st in world's ranking and you play in Challenger 1.
