To fire the Organ Gun, select a target according to the normal rules for shooting, then roll two artillery dice to find out how many shots are fired.

• If one dice rolls a misfire, the firing mechanism is not working properly or it suffers a minor jam. All shots fired from the Organ Gun this turn suffer a -1 To Hit.

• If both dice roll a misfire, no shots are fired and a critical fault has occurred; roll a D6 and consult the Black Powder Misfire Chart in the Warhammer rulebook.

The number of shots fired by the Organ Gun is equal to the total of both artillery dice. After determining the number of shots, roll that number of dice To Hit the target using the crew’s Ballistic Skill and applying all appropriate modifiers. However, the Organ Gun never suffers a To Hit penalty for firing multiple shots.
