In your Command phase, select one enemy unit within 18" and visible to the bearer, then roll one D6: on a 1-2, that enemy unit must take a Battle-shock test; on a 3-4, that enemy unit suffers D3 mortal wounds; on a 5-6, until the start of your next Command phase, each time a model in that enemy unit makes an attack, subtract 1 from the Hit roll.
