This attack happens in any friendly Shooting phase and cannot be made if the unit pushing the Plague Furnace is in combat. In the Shooting phase, place the flame template with the wide end touching the front of the Plague Furnace's base. The entire template must remain in the arc of sight of the Plague Furnace. Any models touched by the template must pass a Toughness test or suffer a single wound with no armour save allowed. It is a Warpstone Weapon.
