Key takeaways
- Current data slightly favors Viktor, but the sample is too limited for a strong conclusion: Viktor wins 52.0% of 225 games (95% range 45.5–58.4%).
- Both champions' overall Bot win rates predict 53.7% for Viktor; the result is within the margin of error of that, so this matchup mostly reflects the two champions' general strength.
- Kai'Sa usually wins the lane: 338 gold ahead of Viktor at 15 minutes on average (118 games with a 15-minute snapshot).
- Viktor players pick Flash + Teleport much less often against Kai'Sa: 77.0% of their other Bot games, 67.8% 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 Viktor and Kai'Sa 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 Viktor'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 Viktor Build vs Kai'Sa
Usual Viktor build (Bot)
83.3% win rate · 12 games
Against Kai'Sa
Not enough matchup-specific build data: only 7 of 88 Viktor games against Kai'Sa carried a complete build, which is too few to recommend an item path from. Use Viktor's standard build instead.
- Viktor usually completes Blackfire Torch first, at 11.0 min (median of 90 games).
- Kai'Sa usually completes Kraken Slayer first, at 11.1 min (median of 91 games).
- Skill priority: E > Q > 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.
