Banner of Defence

The simple device embroidered into this banner in an interlocking pattern actually bides a powerful symbol capable of stopping even a cannon ball in its tracks.
As long as the unit is affected by the Blessing of the Lady all models in a unit with the Banner gain a 4+ Ward save against all missiles (including magic missiles) with Strength 5 or more. If the Blessing of the lady is lost, then the Banner loses this ability.
