Key takeaways

  • Kog'Maw is favored in this matchup: Viktor wins 27.6% of 29 games, and the whole 95% range (14.7–45.7%) is on the same side of 50%.
  • Both champions' overall Bot win rates predict 45.1% for Viktor; the result is within the margin of error of that, so this matchup mostly reflects the two champions' general strength.
  • Viktor players pick Cryptbloom far more often against Kog'Maw: 2.0% of their other Bot games, 10.3% 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 Kog'Maw 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 Kog'Maw

Usual Viktor build (Bot)

73.1% win rate · 26 games

Against Kog'Maw

Not enough matchup-specific build data: only 2 of 17 Viktor games against Kog'Maw 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 11.5 min (median of 20 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.
