If a model with this special rule rolls a natural 6 when making a roll To Wound, the Armour Piercing characteristic of its weapon is improved by the amount shown in brackets after the name of this special rule.

For example, if a natural 6 is rolled when rolling To Wound with a weapon that has an AP of "-" and the Armour Bane (1) special rule its AP counts as being -1 when making an Armour Save roll against that wound.

If a model with this special rule rolls a natural 6 when making a roll To Wound for an attack made in combat, it has struck a ‘Killing Blow’. Enemy models whose troop type is ‘infantry’ or ‘cavalry’ are not permitted an armour or Regeneration save (see page 176) against a Killing Blow (Ward saves can be attempted as normal). If an enemy model whose troop type is ‘infantry’ or ‘cavalry’ suffers an unsaved wound from a Killing Blow, it loses all of its remaining Wounds.

Note that if an attack wounds automatically, this special rule cannot be used.
