Vigilators

This unit cannot be targeted or affected by psychic powers. When a Psychic test or a Deny the Witch test is taken for an enemy model, subtract 1 from the total for each unit from your army with this ability within 18" of that model (to a maximum of -4).

When resolving an attack made by a model in this unit against a PSYKER unit, you can re-roll the wound roll.

If you have an IMPERIUM Warlord (excluding a FALLEN warlord), you can include this unit in a Vanguard Detachment. If you do so, that Detachment's HQ requirements are changed to 0-2 and its Command Benefits are changed to "None".
