When a unit that contains at least one model with this special rule takes Morale checks or Pinning tests, the unit ignore any negative Leadership modifiers. If a unit is both Fearless and Stubborn, the unit uses the rules for Fearless instead.
If a unit contains at least one model with this special rule, and that unit is Charged, every model with the Counterattack special rule gains a number of additional Attacks equal to the value in brackets listed as part of this special rule. If no value is listed then the unit gains +1 Attack. If, when Charged, the unit was already locked in combat or has made the Hold the Line Reaction, the Counterattack special rule has no effect.
A unit that includes any models with this special rule may not be joined by any model that does not also have this special rule (this includes Legion Techmarines and Legion Apothecaries, which may not be assigned to a unit with this special rule unless they also have this special rule).
All models in a unit under the effect of this Hexagrammaton Unit Sub-type reduce the Strength of all attacks made against them with Flame, Plasma, Volkite and Phosphex weapons by -1, and force all attacks made against them with the Poisoned (X) special rule to increase the roll needed to Wound by 1 (to a maximum of 6+).
