The Undead legions of the Vampire Counts march under the command of powerful Necromancers.
Models with this special rule are ‘Undead’. Undead models cannot march (unless they have the Fly (X) special rule and choose to move by flying). In addition, all Undead models have the following universal special rules:
• Fear
• Immune to Psychology
• Unbreakable
• Unstable
A character with this special rule cannot join a unit without this special rule, and vice versa.
