Fear (X) "Models near an enemy Model with the Fear (X) Special Rule must reduce their Advanced Characteristics."
When any Model from a Unit is within 12" of an enemy Model with the Fear (X) Special Rule, all Models in that Unit must reduce their Leadership, Willpower, Cool, and Intelligence Characteristics by the value of X. This negative modifier is removed as soon as no Models in a given Unit are within 12" of any Model with the Fear (X) Special Rule. If a Unit would be affected by multiple instances of the Fear (X) Special Rule, the value of X is not stacked and instead the single highest value is used as a negative modifier.
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.
