Hello everyone! Thank you for reading my guide! This being my first guide I've ever made, so please leave some criticism in the comments! Thank you and I hope this helps!

Pros:
Fast Jungler
strong ganker with his "e" ability
can dive low HP champs well with his ulti
good tower pusher
can counter jungle easily
Super fun to play!

Cons:
Easy to kill if enemy invades jungle early
Squishy all through game (thats why i rush FM)
is easy to counter jungle against
can not solo gank
Expensive build items

My runes are comprised of Armor Pen. marks, Attack speed Glyphs, Armor and magic resist Seals, and Armor pen. Quints.
The reason for this rune page choice is that 1: He needs some bonus attack speed for early and mid game. 2: MR and Armor seals help with squishyness in jungle and in ganks. 3: Lots of armor pen. to do as much damage as possible!

(you can just use flat armor or flat MR seals if you dont have both.

I follow a basic AD carry type mastery setup With the extention into the Utility tree for Increased Neutral Buff duration.

Smite: 100% required (for jungling you derp :P)
Flash: I prefer this spell to mobility based spells like ghost and teleport because his Q can give him plenty of movement speed.

Ghost: I personally think you get more then enough movement speed from your Q but if it works for you then go for it :).
Teleport: I only take it for troll games when i gank by teleporting to wards and stuff :).
CV: for those pro jagler ulti's on people who think their lucky enough to escape from team fights :). (but dont use unless you stay trolling.)

My jungle order goes like this.
1. Blue buff
2. Wolf Camp
3. Wraith Camp
4. Small Golem camp
5. Red buff
6. Wolf camp (or wraiths if its up)
