Jax Guide

Tips for Playing Against Jax

-Against a really good jax it can be hard, but I think many of them don't know what they're doing.
-If he tries to E you, just walk back and Q. If you can't escape the E and you're absolutely cracked you can actually time a grasp auto right at the end of his E that'll go through before you're stunned. (Very difficult to do though.)
-Play in your minions a lot here, that way you can Q and back up if he is spinning in your face, and if he doesn't have E up he takes minion damage.
-If you spit him into tower and have minions nearby, immediately W onto the minions, and you'll probably land on him leaping to the minions.
-Be careful when he has ult, as he simply does a lot of damage while gaining a lot of resistances.
-Be careful when he gets Trinity Force. That item is pretty darn good against TK.

Riftmaker

This item is good in general when ahead, or probably even, even. I think against Jax though it's really nice because even if he spins you'll be able to do a good amount with Q. I probably wouldn't rush it though. Maybe 2nd item?
Swiftness Boots

Swifties helps escape him and run him down. Very good here I think. If their entire team has a lot of CC you might be fine to go Merc's too, but I just love swifties.
Mommy

Dead Man's is probably a good option, even as a rush, but you can certainly get away with Heartsteel first, especially when ahead.
