Key takeaways
- Current data slightly favors Sejuani, but the sample is too limited for a strong conclusion: Naafiri wins 34.2% of 38 games (95% range 21.2–50.1%).
- Both champions' overall Jungle win rates predict 45.3% for Naafiri; the result is within the margin of error of that, so this matchup mostly reflects the two champions' general strength.
- Naafiri usually wins the lane: 480 gold ahead of Sejuani at 15 minutes on average (37 games with a 15-minute snapshot).
- Naafiri players pick Mercury's Treads far more often against Sejuani: 14.5% of their other Jungle games, 31.6% 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 Naafiri and Sejuani 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 Naafiri'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 Naafiri Build vs Sejuani
Usual Naafiri build (Jungle)
77.4% win rate · 31 games
Against Sejuani
Not enough matchup-specific build data: only 3 of 23 Naafiri games against Sejuani carried a complete build, which is too few to recommend an item path from. Use Naafiri's standard build instead.
- Naafiri usually completes Scorchclaw Pup first, at 0.2 min (median of 30 games).
- Sejuani usually completes Mosstomper Seedling first, at 0.2 min (median of 24 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.
