Regeneration (4+) A model with Regeneration gains a Ward Save (indicated by the number in the brackets). This is cumulative with other sources of Regeneration. Regeneration may not be used against Flaming Attacks, successful Killing Blows (including Heroic Killing Blow) or wounds caused due the unit being Unstable.
Undead All units with Undead have Animated Construct, Fear, and Unstable. However, they may make march moves if they are within 12" of the army's General.
