Combos and how to play

Jax is a fighter whose attack speed rises with successive attacks. Leap Strike lets him leap onto a unit, Counter Strike dodges every attack and then stuns nearby enemies, and Grandmaster-at-Arms adds magic damage every third consecutive attack.

The basic combo

Q › W › AA AA

When: An enemy is within leap range.

Leap Strike hits the target, Empower charges your next attack for bonus damage, then your consecutive attacks raise your attack speed.

The dodge and the stun

E › AA AA › E

When: Several enemies attack together.

Counter Strike dodges every attack for a brief moment then stuns nearby enemies: cast it during their attacks, and recast it when the moment is right.

The team fight

R › Q › W › AA AA

When: A team fight starts.

Grandmaster-at-Arms deals magic damage every third attack and can be activated for damage around you and extra resistances.

Laning phase

Leap onto minions or allies to reposition. Keep Counter Strike to dodge an important attack and stun nearby enemies.

Common mistakes

• Using Counter Strike with no attack to dodge.
• Leaping into nothing with no target or exit.
• Interrupting your successive attacks: they raise your attack speed.

Riot's official tips for playing Jax

• Jax can Leap Strike to friendly units, including wards. You can use them to plan your escape.
• Jax benefits greatly from items that have both Ability Power and Attack Damage such as Guinsoo's Rageblade and Hextech Gunblade.
