Supplementary Rules

Firing the Catapult or Trebuchet
To fire the catapult or trebuchet first designate the target by placing a die in the point initially aimed for.  Now roll the directional and distance dice to determine exactly where the shot lands.  Measure the distance from the initial point in the direction of the directional die and place the war machine's template at the new location.  Any figures half or more under the template are potentially damaged.  Wall sections which are under the template are damaged as well - each successful hit reduces the height of the wall by 1 inch.

If a 'Misfire' is rolled with a direction, the machine does not fire this turn.  If a 'Misfire' is rolled with a 'Hit', consult the chart below to determine the effect.
d20 Roll Effect
1-8 Ammunition is dropped and the machine can not fire this turn
9-14 A piece of the mechanism is pushed out of place - machine can not fire this turn or next
15 One crew member suffers a debilitating injury and can no longer participate in the battle
16-19 Machine immediately loses 1 hit point due to a key component breaking
20 The machine is destroyed along with one of the crew

Shooting at War Machines
When shooting at a war machine the hits are randomized between the crew and the machine itself.
Roll a d20 and consult the chart below to determine what will be hit before rolling for damage.
d20 Roll Target
1-15 War Machine
16-20 Crew

Shooting at the Caravan
Shooting at the caravan is similar to shooting at a war machine in that the hits are randomized.  When shooting at the caravan, the cart, driver, or beast of burden could be hit.  If a beast loses all of its hit points, it takes 4 inches of movement to replace it with another.  A caravan driver normally handles a single cart, but it is possible to handle up to two carts at the cost of 2 inches of cart movement per turn.
Roll a d20 and consult the chart below to determine what will be hit before rolling for damage.
d20 Roll Target
1-8 Cart
9-15 Horse or Oxen
16-20 Caravan Driver

Bashing Down Doors
Each turn a door is bashed, the DV of the door is reduced by 1.  Doors are bashed during the melee combat phase.  If defenders are waiting on the other side of the door after being bashed down, combat starts the next round.
