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 'Monster Slaying Blow'. Enemy models whose troop type is monster are not permitted an armour or Regeneration save against a Monster Slaying Blow (Ward saves can be attempted as normal). If an enemy model whose troop type is monster suffers an unsaved wound from a Monster Slaying Blow, it loses all of its remaining Wounds.

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