The Blood of Barbarus

Any Hits with the Rending (X), Murderous Strike (X), Poisoned (X) or Fleshbane special rule allocated to a Warlord with this Trait, or any model with the Legiones Astartes (Death Guard) special rule in a unit he joins, only gain the benefit of those special rules on a D6 roll of a 6 instead of the value listed as part of that special rule. In addition, an army whose Warlord has this Trait may make an additional Reaction during the opposing player’s Shooting phase as long as the Warlord has not been removed as a casualty.
