Null Maiden Vigil

In the Battle-shock step of your opponent's Command phase, if an enemy unit that is either a ^^**Psyker^^** unit or below its Starting Strength is within 12" of one or more ^^**Anathema Psykana^^** models from your army, that enemy unit must take a Battle-shock test. If that unit is below Half-strength, it must subtract 1 from its Battle-shock test this phase instead.
