Jax has always been one of those champions that is just such a total monster to fight and I always hated having to be put up against him in the jungle. To figure out how to counter him I simply decided to play him... now i'm mastery 7 with 200k mastery points. Most of the things I say in this guide are not really the best information since I just started playing last year and ended the season Silver 4. With that out of the way, let's get started. Jungle Jax is in a pretty okay spot with the new runes since you can get free attack speed from the Legend Alacrity rune. Along with that, you can get some free health and armor from using the resolve tab. Now then, for jungling. Usually if I start blue side I will go blue into gromp into wolves, if done right you can get level three at about 2 minutes 32 seconds which is pretty good for a jungler. I like to look at the lanes and see if they are pushed up enough for a good gank. But before you go in for any ganks you need to ask yourself if it's worth it. If you can get a kill or a flash than go for it, but if it looks like you wont get anything just keep farming.
