Olaf vs Jax Counter Pick

The stat sheets are close to identical. Both are melee at 125 attack range, both open at 68 base attack damage, both move at 350, both pay mana. Jax edges base armor at 36 against 35 and base health at 650 against 645, while Olaf pulls ahead by level 18 with 2,668 health to 2,401. With raw numbers this tight the abilities decide everything, and 110 games on patch 16.13.1 put Olaf at 41.8%, a Hard rating.

• Counter Strike inverts the trade. Jax dodges all incoming attacks for its duration and then stuns; Olaf’s damage runs through attack speed granted by Berserker Rage, so he loses more inside that window than most opponents would.
• Relentless Assault compounds. Consecutive attacks keep raising Jax’s attack speed without costing him health, which is the ramp Olaf only gets by being hurt.
• Grandmaster-at-Arms adds magic damage. Every third attack converts, and the shield from Tough It Out does nothing to scale against it.

Reckless Swing stays Olaf’s equaliser because true damage ignores the 107.4 armor Jax carries at level 18, though it costs health on a champion already trading health for output. Undertow thrown before any commitment is close to mandatory, since the armor and move speed reduction is the only way to keep him in place once Leap Strike is spent.
