Master Yi vs Olaf Counter Pick
Matchup Summary
What the Data Means
Olaf’s ultimate makes him immune to disables while he keeps attacking; Master Yi’s makes him immune to slows. Two answers to crowd control collide, and 301 games on patch 16.13.1 give the jungle clash to Master Yi at 56.2%.
Ragnarok also grants Olaf passive armor and magic resistance, and Berserker Rage turns his missing health into attack speed and life steal, so the longer he survives the harder he swings. Undertow reduces armor and move speed on hit, and Reckless Swing deals true damage at the cost of his own health. Against that, Wuju Style’s true damage ignores every resistance Ragnarok provides, and Meditate answers the health-cost economy Olaf runs on by restoring health and reducing damage taken.
Raw statistics split between them. Olaf ends far bulkier at 2,668 health against 2,425 and leads on attack damage, 68 to 65, while Yi holds 175 attack range against 125 and 355 move speed against 350. Reach and mobility decide who commits to a skirmish and who is dragged into one.
Difficulty sits at 3 for Olaf and 4 for Yi, so the result is not a skill-floor mismatch. Olaf’s damage is physical into 33 base armor, and Undertow strips part of that before the duel properly begins. With true damage on both sides, the champion who also controls spacing takes the majority of these 301 recorded fights.
