This match up is very hard if you are not familiar with it but after playing some games you will find it really easy.
Challenger Camille main's guide on this match up (Weeknd)
Smeb Vs. Untara, KT vs SKT, Very good game from Camille on a high level
*Patch 8.6 Introduced a new rune for bruisers called "Conqueror" Don't have enough experience with this rune or any data to place it in the guides, you'll have to try it out yourself and see how it works*
- Arcane Comet Good rune, gives you a good safe poke and helps you gain control over the lane.
- Aftershock Aftershock is really useful in this match up because it helps you mitigate the damage during Jax's E. You can just wait it off and lose next to no hp. Sadly it's cooldown after the nerf is very damaging. I would take it if your team has no tanks or lacks a good engage.
- Phase Rush Pretty useless. Jax has no slows which you could mitigate and he has much less mobility than Camille so you don't need the movement speed buff. I wouldn't take Phase Rush.
- Electrocute I don't think Electrocute helps in a lane with Jax. His E will delay your time to proc Electrocute while the point of this rune is it's burst damage. Not worth the risk to pick it.
Grasp of the Undying Jax is much stronger in extended fights. I haven't tried playing Grasp yet but I would guess it doesn't help enough to be a good pick.
ALSO IMPORTANT TO REMEMBER RUNES ARE OFTEN A PREFERENCE CHOICE BECAUSE ALL OF THEM OFFER DIFFERENT PLAYSTYLES SO DIFFERENT RUNES MAY SUIT DIFFERENT PLAYERS BETTER
Some things to look out for:
This is definitely a skill match up. Try to bait out his E and play around it's cooldown. Watch out for his power spikes and avoid longer fights. If you're losing early game then try to roam and help your teammates (focus immobile targets with your ult).
Fighting Jax 1v1 will be tough throughout the game so make sure you are either fed enough to fight him or got someone from your team to back you up. Try to focus on teamfighting and getting picks rather than split pushing.
First you need to look at your options: note I'm not telling you to buy this items yet!
- Tabi Ninja
- Tiamat
- Phage
- Sheen
So about Tabi Ninja, I think it's a good buy to survive the lane and roam around the map when your team is ahead.
Tiamat I don't like it because it destroys the concept of wave management. You can buy it if you want to push and roam since Jax has weak wave clear. I would avoid buying it because pushing the lane makes you unable to control how long your trades are and when you want to trade.
Sheen Good buy, helps with short trades and highers your true damage which could help after level 6 to get through Jax's resists from his ultimate.
Phage helps thanks to it's raw stats, consider trying it out for yourself, I myself prefer Sheen over it but if you don't have enough gold for Sheen at your first back then consider buying Ruby Crystal and Long Sword to finish Phage later.
