Rek’Sai vs Olaf Counter Pick
Matchup Summary
What the Data Means
Two champions that heal from their own aggression meet here, and Olaf’s version is the better one. Berserker Rage grants him attack speed and life steal scaling with missing health, so he grows stronger as the fight goes badly for him. Rek’Sai’s Fury only becomes health while she is burrowed, which means stepping out of the fight to use it.
Her 44.9% across 118 games on patch 16.13.1 carries a Hard grade. Reckless Swing costs Olaf health and deals true damage, refunding the cost when it finishes the target, and true damage walks straight past the 111.5 armor she reaches at level 18. Her own true damage requires maximum Fury on Furious Bite, so his version is available far more often than hers. Health totals settle the rest: 2,668 for Olaf at level 18 against 2,283. His 68 base attack damage against her 62 also means the very first exchange starts in his favor, before Undertow’s armor reduction is counted at all.
- Reach: 175 attack range against 125 is her only lead in the opening exchange.
- Speed: his 350 base move speed beats 340, and Undertow slows on top of it.
- Escape: Ragnarok’s immunity to disables reduces Void Rush to a damage tool rather than a setup tool.
Both are rated 3 for difficulty, so the gap is entirely in the numbers. Full stats: Rek’Sai.
