Key takeaways

  • Current data slightly favors Kayn, but the sample is too limited for a strong conclusion: Kayn wins 55.1% of 98 games (95% range 45.2–64.6%).
  • Both champions' overall Jungle win rates predict 53.1% for Kayn; the result is within the margin of error of that, so this matchup mostly reflects the two champions' general strength.
  • Diana usually wins the lane: 372 gold ahead of Kayn at 15 minutes on average (95 games with a 15-minute snapshot).
  • Kayn players pick Mercury's Treads far more often against Diana: 19.3% of their other Jungle games, 32.7% 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 Kayn and Diana 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 Kayn'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 Kayn Build vs Diana

Usual Kayn build (Jungle)

76.3% win rate · 38 games

Against Diana

Not enough matchup-specific build data: only 6 of 62 Kayn games against Diana carried a complete build, which is too few to recommend an item path from. Use Kayn's standard build instead.

  • Kayn usually completes Scorchclaw Pup first, at 0.2 min (median of 41 games).
  • Diana usually completes Scorchclaw Pup first, at 0.2 min (median of 58 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.
