Gory Massacre

WHEN: Fight phase.
TARGET: One World Eaters unit from your army that made a Charge move this turn and destroyed one or more enemy units this phase.
EFFECT: In your opponent’s next Command phase, each enemy unit within 6" of your unit must take a Battle-shock test. If the unit taking that test is Below Half-strength, subtract 1 from that test. Enemy units affected by this Stratagem do not need to take any other Battle-shock tests in the same phase.
