Key takeaways

  • Current data slightly favors Ornn, but the sample is too limited for a strong conclusion: Olaf wins 40.4% of 47 games (95% range 27.6–54.7%).
  • Both champions' overall Top win rates predict 47.4% for Olaf; the result is within the margin of error of that, so this matchup mostly reflects the two champions' general strength.
  • Olaf usually wins the lane: 875 gold ahead of Ornn at 15 minutes on average (46 games with a 15-minute snapshot).
  • Olaf players pick Ghost + Barrier far more often against Ornn: under 0.5% of their other Top games, 4.3% here.
How we calculate this

Games: ranked Solo/Duo and Flex games on the North America server from the patch shown. Remakes (games under 5 minutes) are excluded.

A game only counts when Olaf and Ornn played the same position on opposite teams, so roaming, lane swaps within a team or a champion merely being in the same game never count as this matchup.

The 95% range is a Wilson score interval. Confidence comes from how wide that range is: within ±3 points is very high, ±5 high, ±8 moderate, anything wider low. Below 20 games a matchup is not classified at all.

Expected win rate combines both champions’ win rates in this lane (same games and filters) with the log5 formula: E = A(1−B) / (A(1−B) + B(1−A)). Matchup effect = observed − expected.

"What changes" compares Olaf's choices in this matchup with the same champion's other games in the same lane, and lists a change only when it is at least 3 points and statistically significant (two-proportion z-test, |z| ≥ 2, 20+ games).

Results are not split by rank: the sample per rank is too small for honest per-rank matchup numbers.

Best Olaf Build vs Ornn

Usual Olaf build (Top)

83.3% win rate · 24 games

Against Ornn

Not enough matchup-specific build data: only 7 of 32 Olaf games against Ornn carried a complete build, which is too few to recommend an item path from. Use Olaf's standard build instead.

  • Olaf usually completes Stridebreaker first, at 11.8 min (median of 29 games).
  • Ornn usually completes Sunfire Aegis first, at 13.0 min (median of 26 games).
  • Skill priority: Q > E > W — the same as usual.

Builds are ranked by the lower edge of their win rate range, not the raw win rate, so a build seen in a handful of wins never outranks a proven one.
