Terror Descends (Aura) In the Battle-shock step of your opponent's Command phase, if an enemy unit that is below its Starting Strength is within 12" of one or more ^^**Heretic Astartes**^^ units from your army, that enemy unit must take a Battle-shock test.
Each time an enemy unit within 12" of one or more ^^**Heretic Astartes**^^ units from your army takes a Battle-shock test, subtract 1 from the result.
Enemy units affected by this Detachment rule do not need to take any other Battle-shock tests in the same phase.
