Key takeaways
- Current data slightly favors Senna, but the sample is too limited for a strong conclusion: Nautilus wins 47.9% of 240 games (95% range 41.7–54.2%).
- Both champions' overall Support win rates predict 47.7% for Nautilus; the result is within the margin of error of that, so this matchup mostly reflects the two champions' general strength.
- Senna usually wins the lane: 441 gold ahead of Nautilus at 15 minutes on average (236 games with a 15-minute snapshot).
- Nautilus players pick Health Scaling (defense) much less often against Senna: 92.1% of their other Support games, 87.5% 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 Senna 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 Senna
Usual Nautilus build (Support)
60.4% win rate · 540 games
Against Senna
Not enough matchup-specific build data: only 14 of 87 Nautilus games against Senna 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 163 games).
- Senna usually completes Black Cleaver first, at 13.6 min (median of 119 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.
