Undead refers to the Vampire Counts, Tomb Kings and Vampire Coast races and their units.
- Being undead means a unit does not rout in combat, instead they gradually take more and more damage as their binding disintegrates.
- Some effects' descriptions say they apply to undead, for instance The Fellblade.
- There are some exceptions within the undead factions such as Sartosa Free Company, Sylvanian Handgunners and Sylvanian Crossbowmen as they are living humans. As such, they don't have crumbling or disintegrating attributes.
- Some units are technically living (such as Necromancers) but are still counted as undead for the purposes of the game.
