Runes

Skill Order (Lv 1 - 15)

Ult

Prioritize Skill 2 first, as it is an auto-attack reset and your main damage source.

Jax Strengths

✓Strong counter to basic-attack-reliant champions
✓Strong late-game 1v1 and hard-to-stop split pushing
✓Good engage with a targeted leap and an AoE stun

Jax Weaknesses

×Weak early laning and strict mana management
×Relies on cooldowns and is fragile when locked down by CC
×Needs core items before he can take over the game

Jax Early Game

Take favorable trades by negating enemy basic attacks with Skill 3. Don't force kills early; prioritize farming and rush Trinity Force.

Jax Mid Game

Split push in the side lanes and beat anyone who tries to 1v1 you. If several enemies collapse, leap away with Skill 1 and let your team take objectives in the meantime.

Jax Late Game

A full-build Jax is very strong in a 1v1. Keep pressuring the side lane, then use the Teleport boot enchant to join the teamfight from behind and break the enemy team.

Jax Teamfights

Ignore the tanks and leap onto the enemy's squishy backline carries with Skill 1 to draw their focus. Landing the Skill 3 stun on several targets in the middle of their team swings the fight heavily your way.

⚠️ Common Mistakes

Wasting Skill 3 (Counter Strike) on wave clear

Using Skill 3 (Counter Strike) to clear minions is a mistake. It negates basic attacks and stuns, and it is Jax's lifeline. If the enemy all-ins while it's on cooldown, you have no answer. Save it for trades and escaping ganks.

Jax Combos

Jump Stun

Leap with Skill 1 while Skill 3 is spinning, recast Skill 3 to stun, then land the empowered auto from Skill 2.

3(1st)

3(2nd)

Trade Combo

Stack the passive on minions and reset your auto with Skill 2. Use Skill 1 and Skill 3 to chase or disengage.

Our take

This shifts weight from Jax's ultimate cast onto the passive he carries through the whole fight. The passive gains damage at every rank while the active falls from 150 to 100 at rank 1, rewarding sustained attacking over a single burst. More AR per level and a higher attack speed ramp make him steadier the longer a fight runs. Counter Strike's max HP scaling also rises 0.5%, slightly improving his damage into health-stacked targets.

Patch 7.0f

Buff

Grandmaster's Might

Bonus AD gained from AR on hitting a champion40% → 50%
Bonus AD gained from MR on hitting a champion24% → 30%

Our take

Grandmaster's Might builds Jax up every time he connects with a champion, which is why the longer a brawl runs the better it goes for him. Raising the AR-based scaling from 40% to 50% and the MR-based scaling from 24% to 30% means the payoff grows with every defensive item he finishes. If he can stay in the middle of a teamfight and keep landing hits on several targets, he is far more likely to still be standing when it ends.
