Begin at Bluebuff. Use Counter Strikeas often as possible and Smiteto lasthitt Blue. Go on with wolves but use EmpowerONLY to lasthitt the giant wolf.
Kill Wraiths and Golems.Kill the two litle lizards and go back for Ninja Tabithan take Lizardbuff. Now you can gang.
afert first gang go back in jungle. Jax get after lvl 6 very fast higher lvls, so ha can catch up what he maby lost in the beginning.

You need as much dodge as possible, so Greater Quint of Evasionand Greater Seal of Evasionare irrecoverable. cool down is also very important at the geginning.
you can take Greater Mark of Desolation or Greater Mark of Alacrity.

Cloth Armorand 5x Health Potionare normal jungle equip and a good start.
Your boots are your most important item.
Than you need life steal to making jungling much easier. First Vampiric Scepterthan Hextech Revolverexcept you got enough gold to buy Hextech first.
Hextech Gunbladeand Guinsoo's Ragebladeare must haves, after these two items you can by whatever you need, tank, ad, ap items. These three i listed here are very powerful but if your team has much ap get somthing different.

first: get Counter Strike,you wont survie blue without.
second: Empower, gives you some extra dmg for low mana.
third: again, to get less cool down
fourth: Leap Strike, you need this for your gang, without you dont have the element of surprise.
after lvl four your skill order isnt important for jungling anymore.

Cons

-slow jungling till lvl 6
-first gang is dificult
-a bit lucky how often you dodge
-mana problems without bluebuff

Pros

-Very powerfull in late game
-After lvl 6 very fast jungler
-dont need any special jungle items so "normal equip" in middle and late game
-"suprise i´m back"
