Key takeaways

  • Current data slightly favors Kassadin, but the sample is too limited for a strong conclusion: Locke wins 35.1% of 37 games (95% range 21.8–51.2%).
  • Both champions' overall Mid win rates predict 50.0% for Locke; the result is within the margin of error of that, so this matchup mostly reflects the two champions' general strength.
  • Neither side reliably wins the lane: the average gold difference at 15 minutes is 249, within the margin of error (35 games).
  • Locke players pick Approach Velocity far more often against Kassadin: under 0.5% of their other Mid games, 5.4% 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 Locke and Kassadin 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 Locke'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.

What Locke Changes Against Kassadin

Choices Locke players make noticeably more or less often in this matchup than in their other Mid games.

Best Locke Build vs Kassadin

Usual Locke build (Mid)

100.0% win rate · 11 games

Against Kassadin

Not enough matchup-specific build data: only 4 of 22 Locke games against Kassadin carried a complete build, which is too few to recommend an item path from. Use Locke's standard build instead.

  • Locke usually completes Lich Bane first, at 10.9 min (median of 30 games).
  • Kassadin usually completes Rod of Ages first, at 10.2 min (median of 25 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.
