Corposant Stave

‘For each Hit inflicted on a unit that contains at least one model with the Vehicle, Dreadnought or Automata Unit Type, roll a D6 to determine the effect rather than rolling To Wound or for armour penetration normally. AP has no effect on this roll:
D6 Result
1: No Effect.
2-5: Vehicles suffer a Glancing Hit, other models suffer 1 Wound. Only Invulnerable Saves or Damage Mitigation rolls may be taken against Wounds inflicted by this result.
6: Vehicles suffer a Penetrating Hit, Dreadnoughts and Automata suffer 1 Wound. No Saves or Damage Mitigation rolls may be taken against Wounds inflicted by this result.

A model attacking with this weapon never receives +1 Attack for fighting with two Melee weapons (see page 177).
