Key takeaways
- Current data slightly favors Diana, but the sample is too limited for a strong conclusion: Zed wins 46.2% of 340 games (95% range 40.9–51.5%).
- Both champions' overall Mid win rates predict 49.7% for Zed; 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 15, within the margin of error (132 games).
- Zed players pick Axiom Arc much less often against Diana: 30.7% of their other Mid games, 19.7% 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 Zed and Diana 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 Zed'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 Zed Build vs Diana
Against Diana
Not enough matchup-specific build data: only 9 of 89 Zed games against Diana carried a complete build, which is too few to recommend an item path from. Use Zed's standard build instead.
- Zed usually completes Voltaic Cyclosword first, at 10.8 min (median of 79 games).
- Diana usually completes Stormsurge first, at 10.3 min (median of 79 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.
