Why you do a Bloodthirster, insteasd of doing that do a gun.
And you do Warmog's Armor but you do a Madred's Bloodrazor instead of that do a Atma's Impaler

great guide, but jungle jax > lane jax, dont you think?

Your masteries and skill sequence are a lot messed up and don't make sense.
Also when you buy vampiric scepter on jax you go for cutlass than hextech gunblade and when you get phage you go for frozen mallet because of slow and more hp.
Bloodthirster is worth to buy only with full stacks but without it, worthless item.
Also you forgot that you have great active on hextech that is awesome but I dunno why no one use it.....
On the end atma would fit in better, if you get frozen mallet and warmogs armor from atma you will get at least 70ad!
Bloodrazor is more situational item.

muy buena guia sobretodo el jungleador

very good

Good guide i think in my opinion, i know everybody knows the jungle routes but u may want to add a section for it in.

Empower has a 3 second cooldown at level 5 unless you build cooldown reduction (not recommended) on Jax.

Otherwise you are right, AP still scales well ... but now AD scales better and will generally do more damage for lower cost items.

But Hybrid Jax can still be viable and I'm going to add a hybrid build here when I get a chance.

your ult DOES proc spell vamp. and your 1 sec cooldown empower scales with ap... and your 3rd hits scale with ap! and your leap scales with ap... ap and spell vamp are still very good on jax.
