And what is up Ladies and Gents, Wisteria here showing you how I play Jax in the jungle. Did this out of boredom and is my first guide so don't expect too much, editing in progress.
Will elaborate on each stuff. Who the hell am I kidding, so watch Trick2G's "my way"

Runes you can go with whatever you'd like. Mine is inspired by Trick2G but his has 0 MR and that is pretty damned squishy if your enemy is LeBlanc or some @#$%. So yea, I chose MR over 5% CDR glyphs.

Depends on you really, you can choose to either Max out Q or W first, then followed by R and E.

Flash and Smite would be the default, take TP if you wanna backdoor and don't need flash.

idgaf what you buy, but you need the force, Tri-Force.

Jax my way in the jungle.

Pros:
-Has the most eyes.
-Split pushing God.
-Pretty much only needs Tri-Force+BotRK.

Cons:
-Quite squishy.
-Can't initiate or have to back off if E is on cooldown.
-Needs decent amount of gold.

What's that? Can it be eaten? Just split push unless your team is kinda @#$%-ed.
