Description: A model which loses one or more Wounds to an attack with this special rule and survives has its Toughness value reduced by -1 for the rest of the battle. This effect is not cumulative with other attacks using the Rad-phage special rule, but can be stacked with other special rules that also reduce the Toughness Characteristic of the target. Note that this special rule can never reduce a model to a Toughness value of less than 1.
