Rammus vs Olaf Counter Pick
Matchup Summary
What the Data Means
Ragnarok is the entire problem. Olaf’s ultimate makes him immune to disables for as long as he keeps attacking, and Rammus’s only reliable lock is Frenzying Taunt. Remove the taunt and what remains is a 125-range tank with a telegraphed Powerball trying to survive a berserker who cannot be controlled.
The record agrees. Rammus loses at 45.6% over 136 games on patch 16.13.1, graded Hard. Reckless Swing compounds it because true damage ignores resistances outright, so 111.5 armor at level 18 buys nothing against it, and Berserker Rage grants more attack speed and life steal as Olaf’s health drops. A fight that looks won gets more dangerous the longer it runs.
Undertow reduces armor and move speed at the same time. Since Spiked Shell scales Rammus’s Attack Damage off Armor and Magic Resistance, shredding his armor cuts his defense and his offense with one throw. Olaf moves at 350 against 335 and reaches 2,668 health at level 18 against 2,345, so walking away is not realistic either, and his 68 base attack damage leads 65 from the first minute. Rammus is rated 5 on the difficulty scale and Olaf 3, which means nothing here is fixed by cleaner execution — the answer is to farm a different quarter of the map. Reference stats are on Olaf.
