Divine+ games on one patch. An edge is what happens when a hero is picked into another, not a controlled test; the dots show how strongly a matchup stands out among all counters. In lane an edge counts only what the matchup does beyond both heroes' general lane strength. A reason is shown only where Valve's own spell or item text and the data agree; a rule of the game is a fact from Valve's files, not a measurement.
