All Psykers, friend or foe, within 12" of a model with this special rule have -3 Leadership, do not generate any Warp Charge (i.e. they do not add dice to their owning player's Warp Charge Pool in the Psychic phase) and only harness Warp Charge points on a roll of 6, even if the unit would otherwise harness Warp Charge on another result. A unit that includes any models with this special rule can never be targeted or affected by psychic powers - other units in the unit's vicinity that are hit by beam or nova powers, or by witchfire powers that use templates, are hit/ affected normally. Any blessing or malediction psychic powers affecting a unit are immediately nullified if the unit moves within 12" of a model with this special rule or vice versa. The Psychic Abomination special rule does not apply whilst the unit with this special rule is embarked in a Transport or building.
Models with the Bane of Psykers special rule gain the Precision Shots and Precision Strikes special rules when targeting an enemy unit containing at least one Psyker (i.e. a model with the Psyker, Brotherhood of Psykers/Sorcerers or Psychic Pilot special rule), and can re-roll all failed To Hit rolls when targeting these units.
At the start of each Fight sub-phase, a unit in base contact with one or more enemy models that cause Fear must take a Leadership test (called a Fear test) before any blows are struck. If the test is passed, all is well and there is no effect. If the test is failed, the unit succumbs to fear - all models in the unit have their Weapon Skill reduced to 1 for the remainder of that Fight sub-phase. Note that a model that causes Fear is not itself immune to Fear, and will still need to take a Fear test if it is base contact with any enemy models that cause Fear.
Units containing one or more models with the Fearless special rule automatically pass Pinning, Fear, Regroup tests and Morale checks, but cannot Go to Ground and cannot choose to fail a Morale check due to the Our Weapons Are Useless rule. If a unit has Gone to Ground and then gains the Fearless special rule, all the effects of Go to Ground are immediately cancelled.
