Whenever the wearer of an armour engraved with one or more Runes of Retribution rolls a successful Shield Wall Aegis Save (including Shield Wall stacked with Rune of Shielding), the wearer immediately inflicts a hit with the Strength and Armour Penetration
of the saved attack against the model that caused the wound, before any casualties are removed, distributed onto the model’s Health Pool. This is considered a Special Attack.
