Where these numbers come from
Read from the game's database tables for patch 9.0 (main_units, land_units, battle_entities, melee_weapons, projectiles…) as published in the WH3-Dump export (commit 8a4f7e64). Formulas that turn table values into card values are checked against known units before they are shown — how we verify.
