Who can field it

  • High Elves · Lothern

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.

The game also has 1 summoned or scripted copy of this unit that no building or mercenary pool recruits (wh3_dlc27_hef_mon_merwyrm_summoned).

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.
