Main rune set

Greater Mark of Alacrity You don't really need armor pen or magic pen, because all of your skills are used to get closer to the enemy by any way. You can trick them with your R, slow them with your E, or just teleport right next to them with your Q. None of this needs armour once you can start pwning em. Moreover, the attack speed boost will also be applied to your clone. Greater Seal of resistance Greater Seal of resistance You just can't jungle without it. Well, you can, but you will fail.

_____

Greater Glyph of Alacrity Just like Marks. Greater Quintessence of Desolation Greater Quintessence of Desolation This is the only kind of armor penetration you'll ever need. Usefull or early game.

Ignite Don't even try to jungle without it. On early game, lizard would eat you, and golem would crush you. It's amazing to secure your buffs, to steal dragon and nashor, and to get a little gold boost. Ignite You don't know how frustrating it is to suceed a gank, and to see someone escaping with a few HP. Use it wisely, either on a low life opponent, or on someone who uses HP regen (Mundo, Irelia...)

_____

Your initiating / Escaping ability. Don't you ever underestimate it, it will always save you if used wisely.

• When you want to gank, wait for an opponent lane to push. Make sure that it is not warded, by asking your teammates. The stealth lasts for 3.5 seconds, it's HUGE. On top and bot, you can go from the river to the bushes without being seen.
  
  Wait for a minion wave to pass by, get stealthed, drop a box on the retreat way of your opponents, and strike them (from behind). If you place your Jack in the box wisely, most of them will directly flash on it, wasting their time, their flash, and giving you a free kill.
  
• Tip/trick here.
  When you want to escape from an opponent, get next to a wall, and use your Q. Most of the time, if you are low life, the opponent will flash over the wall, and he'll kill you anyway. That's why you should not get over the wall. Most of the time, look for a nearby bush, and use your Q to reach it. Your oppoenent will flash behind to wall, chasing you (you're stealthed, he'll keep on walking), and by the time he'll realized he ahd been tricked, you will B.
  

Explain the ability here. Don't mention things that are in the tooltip already.

• You will need this to jungle quickly. You can choose to dual buff, then, at the very beginning, ask your whole team to get around blue buff, while you drop 5 boxes right behing the lizard. Once it's done, rush to the blue golem. If you acted perfectly, at 1:54, the lizard will spawn, the boxes will kill him, you will reach blue golem camp, pwn it with your team, you will be lvl 2, with full HP. Kill the wolves, then the golems, then the Wraiths, head back to the wolves, and you're done, you can B and buy your razor.
  
  
• If by any chance, you're in a mess, and you have not enough mana to cast your A, drop a box in front of you, and walk over it, make sure that the opponent follows you.

Your bread and butter. Low life opponent ? Deceive, Two-shiv poison, dead. Need to gank ? Deceive, Jack in the box, Two-shiv poison, dead. Need to KS ? .... Two-shiv poison, dead.

• Unfortunately, if you throw it on an opponent which is about to get into a bush, it will cancel the spell. Make sure that you have enough time to end the "throwing animation".
  
  
• Always remember, you have a 1 AP ratio on this skill. This is the one and only reason why I use malady. Extra AS, and even if your opponent gets heanvy AP res, you will be able to last hit him with your Two shiv.

To be perfectly honest, this is a complete ****. Your clone is not "you", since even with minions around you, the tower will focus it. Buffs doesn't appear on him (useful, for a jungler...). Last but not least, any clever enemy will understand that if a Shaco doesn't cast a spell, gets half-HPed by a soraka, and can't do much but running around and hitting minions, there's a few chances for it to be a clone...

• The ONLY utility of this spell is that it makes you disappear when you cast it. Karthus ultimate ? R. Maokai roots ? R. Sion stun ? R.
  
  

Pretty self explanatory. When you deceive, hit from behind. When you jungle, cast your JitB behind minions.

Health Potion Try to drink it on your first jungling path. I usually end it with a last potion, but never think of selling it back -_-. Clothe armor Clothe armor Jungling, huh ?

Wriggle's Lantern Any jungler needs this. Ward Dragon til 25, then start warding both Dragon and Nashor. Remember, as a Jungler, your role is to GANK and to ward the river, NOT to protect your allies. Top and bot bushes shall be warded by laners ! Berserker's Greaves Nice moving speed combined with Trinity Force, and some extra AS is always nice. Trinity Force Your CORE item. Gives you everything you need. To be honest, by the time you get this, you should already have something like/3/1/x, and once you get it, it's over.
