About and Data Sources

Where the data comes from

Patch notes and hero announcements: Valve's posts on Steam, read through the Steam news API. Copied line by line, with a link to each original post.
Heroes, abilities, items, ranks: the game files, as parsed by deadlock-api.com. Names and descriptions are the game's own.
Win rates, pick rates, builds, matchups, rank distribution: match data from deadlock-api.com, a community project that collects public match results. It does not see every match, but its sample is large: the current window has 545,732 matches.

The match window

Stats cover the time since Valve's most recent balance patch (currently Oct 5, 2026 to Oct 13, 2026). If a patch is less than two days old, the site uses the last seven days instead until there are enough games. "Change" compares the window with the same number of days before it. "All ranks" includes ranked and unranked matches; the rank buttons use ranked matches only, grouped by the average rank of both teams.

How tiers are calculated

Each hero's win rate is pulled toward 50% by 300 games: (wins + 150) ÷ (games + 300). Heroes with tens of thousands of games barely move; heroes with a few hundred move a lot.
Score = 0.85 × how far that win rate is from the average (in standard deviations) + 0.15 × the same for pick rate, with the pick-rate part capped at ±2.
S: score ≥ 1.0 · A: ≥ 0.35 · B: ≥ −0.35 · C: ≥ −1.0 · D: below. Heroes with fewer than 400 games in a bracket are not ranked.

Items use the same steps, but each item is compared only with items of the same cost. Builds list the items a hero's players buy most at each shop tier, not a guide writer's picks.
