Gold for gold

COMPUTEDAt equal gold it beats 91.9% of the game's 99 monsters units in melee. Per 1,000 gold: 39.6 damage per second against Chaos Warriors; it lasts 42.1 s against one unit of them.

Beats, at a similar price: Ancient Stegadon (Engine of the Gods) (4.96× faster), Ancient Stegadon (4.71× faster), Flamespyre Phoenix (4.30× faster)

Loses to, at a similar price: Curs'd Ettin (1.52× slower), Chaos Giant (1.48× slower), Terracotta Sentinel (1.20× slower)

Equal gold, every model fighting at its weapon's attack interval, combat calculator formulas; no charge, mass, splash, leadership or abilities. “Similar price”: within 30% of its 1,900 multiplayer gold.

Who can field it

  • Greenskins · Grimgor's 'Ardboyz · extended roster

Custom Battle lists factions under each race; every faction of a race fields that race's units (units_custom_battle_permissions rows of any of its factions). The name after the race is the faction the army builder uses.

Extended roster: every race above has this unit only through campaign_exclusive rows of units_custom_battle_permissions — CA's note: such units are “filtered out of matchmaking and are generally disabled when unit caps setting is enabled” (“Unable to recruit with unit caps enabled”). So: Custom Battle with Unit caps off, at the multiplayer cost, but not in ranked battles. Race rankings and best-unit lists leave such a unit out for those races.

Where these numbers come from

Read from the game's database tables for patch 9.0.4 (main_units, land_units, battle_entities, melee_weapons, projectiles…) as published in the WH3-Dump export (commit 099796e8). Formulas that turn table values into card values are checked against known units before they are shown — how we verify.
