Key takeaways
- Current data slightly favors Illaoi, but the sample is too limited for a strong conclusion: Cho'Gath wins 45.8% of 96 games (95% range 36.2–55.8%).
- Both champions' overall Top win rates predict 52.2% for Cho'Gath; the result is within the margin of error of that, so this matchup mostly reflects the two champions' general strength.
- Illaoi usually wins the lane: 1,010 gold ahead of Cho'Gath at 15 minutes on average (92 games with a 15-minute snapshot).
- Cho'Gath players pick Hollow Radiance much less often against Illaoi: 26.5% of their other Top games, 7.3% 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 Cho'Gath and Illaoi 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 Cho'Gath'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 Cho'Gath Build vs Illaoi
Usual Cho'Gath build (Top)
90.0% win rate · 10 games
Against Illaoi
Not enough matchup-specific build data: only 8 of 58 Cho'Gath games against Illaoi carried a complete build, which is too few to recommend an item path from. Use Cho'Gath's standard build instead.
- Cho'Gath usually completes Heartsteel first, at 14.4 min (median of 49 games).
- Illaoi usually completes Black Cleaver first, at 12.2 min (median of 63 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.
