Key takeaways

  • Current data slightly favors Amumu, but the sample is too limited for a strong conclusion: Lee Sin wins 42.9% of 119 games (95% range 34.3–51.8%).
  • Both champions' overall Jungle win rates predict 45.5% for Lee Sin; the result is within the margin of error of that, so this matchup mostly reflects the two champions' general strength.
  • Lee Sin usually wins the lane: 409 gold ahead of Amumu at 15 minutes on average (117 games with a 15-minute snapshot).
  • Lee Sin players pick Plated Steelcaps much less often against Amumu: 46.5% of their other Jungle games, 20.2% 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 Lee Sin and Amumu 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 Lee Sin'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.

Choices Lee Sin players make noticeably more or less often in this matchup than in their other Jungle games.

Best Lee Sin Build vs Amumu

Usual Lee Sin build (Jungle)

63.3% win rate · 79 games

Against Amumu

Not enough matchup-specific build data: only 12 of 79 Lee Sin games against Amumu carried a complete build, which is too few to recommend an item path from. Use Lee Sin's standard build instead.

  • Lee Sin usually completes Scorchclaw Pup first, at 0.2 min (median of 81 games).
  • Amumu usually completes Mosstomper Seedling first, at 0.2 min (median of 82 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.
