Description: • A unit that includes at least one model with the Anathema Sub-type may not be directly targeted by any Psychic Power or use any Psychic power or make attacks with a Psychic Weapon, Psychic Powers whose effects would otherwise be applied to a unit that includes at least one model with the Anathema Sub-type (due to area of effect, scattering or other rules) have no effect, but are not cancelled and may continue to affect other units.
• A model with the Anathema Sub-type that is allocated Wounds caused by a Psychic Weapon (which is any weapon granted to a unit or model by a Psychic Discipline) will always fail to Wound without any dice being rolled and any special rules attached to that Psychic Weapon will not trigger. Any Wounds allocated to a model with the Anathema Unit Sub-type caused by a Force Weapon gain no benefit from the Force special rules, but are otherwise resolved as normal. These effects do not apply to a model with the Transport Sub-type that has models with the Anathema Sub-type Embarked within, unless the model with the Transport Sub-type also has the Anathema Sub-type.
• All models that no not have the Anathema Sub-type but are part of a unit that includes one of more models with the Anathema Sub-type, suffer a penalty of -2 to their Leadership Characteristic. Any unit with at least one model within 6" of a model with th eAnathema Sub-type suffers a penalty of -1 to the Leadership of all models in the unit that do not also have the Anathema Sub-type, or -2 if that unit includes one of more models with the Corrupted Unit Sub-type. Note that these two penalties are not cumulative; they apply only the more severe penalty. However, they do stack with other special that modify Leadership (such as Fear (X)).
• A unit that is Embarked on a Vehicle, Fortification or Building suffers no penalties to its Leadership Characteristic due to the Anathema Sub-type, However, units with the Stubborn special rule do suffer penalties to their Leadership from the effects of this Sub-type (note that this only applies to the Stubborn special rule, and other special rules that ignore panalties to Leadership ignore the effects of the Anathema Sub-type).

In addition, the Leadership Characteristic of a model with the Anathema Unit Sub-type can only be used for a Leadership test or Morale check if all models in that unit have the Anathema Unit Sub-type
