Bite of the Betrayed: This Gambit can only be selected during the first Face-Off Step of a Challenge. If this Gambit is selected, until this Challenge ends, modify this Model's Weapon Skill, Strength, and Toughness Characteristics by +1.
Hatred (X) "The Hatred (X) Special Rule grants bonuses against enemies of a specific Faction, Type or Trait."
When Locked in Combat, or Engaged in a Challenge, with any enemy Models that have the Type or Trait that is the value of X, then all Models with this variant of the Hatred (X) Special Rule gain a bonus of +1 to all Wound Tests made in that Combat.
Officer of the Line (X) "Models with this Special Rule allow more Auxiliary Detachments to be included in an Army."
If a Model with this Special Rule is selected to fill a Command Slot in any Detachment in the Crusade Force Organization Chart, then the Controlling Player may select a number of Auxiliary Detachments equal to the value of X in the specific variant of this Special Rule instead of just one.
