Doomfire

The Hellcannon can only make Doomfire attacks if its crew are within 1" of the war machine in the shooting phase. To make a Doomfire attack, pick an enemy unit within range, even if it is not visible to the Hellcannon, and roll to hit. Add 1 to the hit roll if the Hellcannon did not move in your preceding movement phase and add another 1 if the target unit has 20 or more models. A unit hit by Doomfire suffers D6 mortal wounds.
