Key takeaways
- Current data slightly favors Karma, but the sample is too limited for a strong conclusion: Nautilus wins 48.3% of 230 games (95% range 41.9–54.7%).
- Both champions' overall Support win rates predict 49.1% for Nautilus; the result is within the margin of error of that, so this matchup mostly reflects the two champions' general strength.
- Neither side reliably wins the lane: the average gold difference at 15 minutes is 90, within the margin of error (226 games).
- Nautilus players pick Thornmail much less often against Karma: 47.2% of their other Support games, 33.0% 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 Nautilus and Karma 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 Nautilus'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 Nautilus Build vs Karma
Usual Nautilus build (Support)
60.9% win rate · 552 games
Against Karma
Not enough matchup-specific build data: only 14 of 81 Nautilus games against Karma carried a complete build, which is too few to recommend an item path from. Use Nautilus's standard build instead.
- Nautilus usually completes Locket of the Iron Solari first, at 13.4 min (median of 173 games).
- Karma usually completes Echoes of Helia first, at 12.7 min (median of 96 games).
- Skill priority: Q > W > E — 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.
