Key takeaways
- Current data slightly favors Nami, but the sample is too limited for a strong conclusion: Nami wins 54.6% of 119 games (95% range 45.7–63.3%).
- Both champions' overall Support win rates predict 51.6% for Nami; the result is within the margin of error of that, so this matchup mostly reflects the two champions' general strength.
- Swain usually wins the lane: 397 gold ahead of Nami at 15 minutes on average (115 games with a 15-minute snapshot).
- Nami players pick Health Scaling (defense) far more often against Swain: 83.3% of their other Support games, 91.6% 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 Nami and Swain 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 Nami'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 Nami Build vs Swain
Usual Nami build (Support)
90.0% win rate · 10 games
Against Swain
Not enough matchup-specific build data: only 7 of 49 Nami games against Swain carried a complete build, which is too few to recommend an item path from. Use Nami's standard build instead.
- Nami usually completes Echoes of Helia first, at 12.6 min (median of 49 games).
- Swain usually completes Rylai's Crystal Scepter first, at 13.2 min (median of 77 games).
- Skill priority: W > E > Q — 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.
