The Flawless Host

If your army is Battle-forged, all CHARACTER, INFANTRY, BIKERS and HELBRUTE units in FLAWLESS HOST Detachments gain the following ability: Each time you roll a hit roll of 6+ for an attack made by a model with this trait in the Fight phase, it can immediately make an extra attack against the same unit using the same weapon (this is in addtion to any extra attacks granted by the Death to the False Emperor ability). These extra attacks cannot themselves generate any further attacks.
