Hello, this is a simple, easy to understand, quick Shaco jungle guide.

This guide will show you how to be extremely successful and competent as Shaco, he is a really easy jungle and he is amazing fun to play.

Pros:
-Stupidly easy to jungle with
-Epic ganks and scaling to late game
-Relatively Safe jungle due to Deceive
-The most fun to play with in game if done correctly

Cons:
-People WILL complain if you do well
-If you get starved its hard to come back but its rare

Start by running to your blue's bush, set up Jack in the boxes and wait for spawn.
Make sure your team mates protect your jungle from ganks early on.
pull blue by one auto attack and walk into bush, your boxes will do it all, smite to finish off. You will be level 2 so get deceive, head to wolves and kill, use health pots when nessicary during you're jungle. then move to Wraiths, then Red buff, then golems, head back down to wraiths(They will spawn again) then to wolves.

At any point in the jungle rotation, even straight after blue you can head to a lane that needs it and gank. I recommend going back at 700 gold to buy your Madred's Razors. Then save and buy Wriggle's and Normal boots on next back, then follow just follow the build.

Simple.
Seals - Armour
Glyphs - Magic Resist
Marks - Armour Penetration
Quintessences - Armour Penetration

This allows a stable defence from both the jungle and any champion, honestly a great choice for early game defence. The Armour Penetration helps massively with damage throughout the game.

Simple offensive masteries. See above :L
Gives a great boost to your damage and the small amount of defence you need for surviving encounters.
Ignite for ensuring ganks finish correctly and damage and smite for obvious reasons.

Start with: Cloth armour + 5 health pots
Build into Madred's Razors on First back
Then Boots of Mobility, Finish your Wriggle's Lantern
Then get a Trinity Force, starting with Phage into Sheen into Zeal.
A Bloodthirster next for Damage and Sustain
Then a Warmog's and a Guardian Angel to finish for defence if the game is still going on. You should have won though.

Shaco is really fun and the only thing left is to go out and try him, have fun :D
