Hello, wlecome into my Shaco guide
This is my first guide so please don't be to bad :)
I hope you'll enjoy reading and i wish it will help you to play the Demon Jester :)
Good reading :)

You need your W to clear your first camp
Upgrade your Q if u go counter jungle, otherwise you can get your E
Then max your E to deal more damage
Max your Q in second for the % of critical damage
And finally your W.
Don't forget to upgrade your R at level 6, 11 and 16

I like this masteries page because :
- Green : You need move speed as Shaco to go faster countering jungle after your first camp, and overall you need to go fast on the map as a jungler
- Blue Recovery will help you to sustain in jungle, while Though Skin and Bladed armor will help you in the jungle
- Red :Butcher/Feast for some sustain in jungle, the masteries are made in order to deal tons of damage when you go counter jungle the first time to kill the enemy jungler
Frenzy is good as it will automaticly give you 1 stack of it when you use your Q

Armor Seals will help you to take less damage in the jungle
Attack speed Marks and Glyphs will help you to clear faster your jungle
Attack damage Quints will help you to kill the enemy jungler as you will deal more damage with your Q when it crit
Magic resist Glyph are here to give you some MR

You don't need a Flash with Shaco because you have your Q so i take an Ignite, it will help you to kill the enemy jungler and when you gank
And of course, a smite becaus eyou are a jungler

Pros :
- Very good early
- Very mobile
- Can easily one shot low hp target
- High damage if you are fed

Cons :
- Very dependant of getting fed early
- Not very tanky
- Can be counter by pink ward or red trinket

Early game :
If you want counter jungle, start at red or blue and go to the enemy buff, if he's here you can kill him or just steal his buff. You counter every jungler at this moment of the game
If he's not here, just steal the buff
Then clear your jungle and if u have more than 50% of hp, you can gank a lane or just back
Get your first item and gank as often as you can but don't get greedy.
If you can, try to get dragon at level 6, place your clone and stay behind the dragon to activate your passive

Mid/End game and Teamfight :
Try to focus and carry such as adc or midlaners, you have to kill him as fast as possible.
Don't stay in eemy vision, you have to suprise them. If they all come on you, use your ult to try to escape or juke spells
Be carefull of pink ward

That's all for this Shaco guide, I hope you enjoyed and learned something
