Jax vs Olaf Counter Pick
Matchup Summary
What the Data Means
A 110 game sample on patch 16.13.1 caps how much weight the 58.2 percent result can carry, and the matchup deserves a closer look than the number suggests, because Olaf owns several of the tools that normally beat Jax.
Ragnarok makes Olaf immune to disables for as long as he keeps attacking, so the stun at the end of Counter Strike simply does not land while it is running. Reckless Swing deals true damage, bypassing the armor Jax grows to 107.4 at eighteen, and Berserker Rage converts his own missing health into attack speed and life steal. He finishes with 2,668 health at level 18, comfortably above 2,401, and both champions share 350 movement speed, 68 attack damage and 125 attack range.
What tilts it back is timing. Ragnarok has a duration, and Counter Strike can be held until it ends rather than spent into it. Undertow must land for the slow and the armor reduction to apply, and a difficulty rating of 3 against 5 describes a kit with fewer decisions and fewer outs. Jax also deals mixed damage, which the flat armor and magic resistance that Ragnarok grants Olaf only half addresses. Tough It Out layers a shield on top of that attack speed, so the cleanest opening is the handful of seconds after the ultimate expires.
