Key takeaways
- Current data slightly favors Yone, but the sample is too limited for a strong conclusion: Kassadin wins 46.5% of 142 games (95% range 38.5–54.7%).
- Both champions' overall Mid win rates predict 47.9% for Kassadin; the result is within the margin of error of that, so this matchup mostly reflects the two champions' general strength.
- Yone usually wins the lane: 604 gold ahead of Kassadin at 15 minutes on average (65 games with a 15-minute snapshot).
- Kassadin players pick Chainlaced Crushers much less often against Yone: 21.0% of their other Mid games, under 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 Kassadin and Yone 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 Kassadin'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 Kassadin Build vs Yone
Usual Kassadin build (Mid)
89.8% win rate · 49 games
Against Yone
Not enough matchup-specific build data: only 10 of 40 Kassadin games against Yone carried a complete build, which is too few to recommend an item path from. Use Kassadin's standard build instead.
- Kassadin usually completes Rod of Ages first, at 10.9 min (median of 46 games).
- Yone usually completes Immortal Shieldbow first, at 12.6 min (median of 40 games).
- Skill priority: E > W > 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.
