Shred (X) "Attacks made with the Shred (X) Special Rule can sometimes inflict an extra point of Damage"
When any Wound Test is made for an attack with the Shred (X) Special Rule, if the result of the Dice roll, before any modifiers are applied, is equal to or greater than the value of X attached to this variant of the Shred (X) Special Rule, then if a wound is inflicted by that Wound Test , the Damage of that wound is increased by 1. Note that the Shred (X) Special Rule may only be triggered by a Wound Test and has no effect when making an Armour Penetration Test.
