The Papal Bombard is the Italian replacement of the Heavy Cannon, and as such, it can only be obtained via shipments from the Home City or by slowly producing it in a Factory. Like Heavy Cannons, Papal Bombards are slow to move and deploy, but powerful and effective against all units and buildings. However, the Papal Bombard has the ability to absorb some damage incurred by other artillery units, a trait it shares with the Papal Guard.
Additionally, with the Papal Arsenal Home City Card, Papal Bombards gain a charged ability called "Holy Fire," which is a powerful incendiary area-of-effect attack that has a cooldown.
Holy Fire (requires the Papal Arsenal shipment; has a cooldown of 60 seconds): The Papal Bombard fires an incendiary projectile which deals 430 damage (215 against Artillery and Arrow Knights, 322.5 against Cavalry and Shock Infantry, 1075 against Fixed Gun), has a maximum range of 28 and an AOE of 7.
Basilica shipments arrive 33% faster; Papal Bombards get the 'Holy Fire' action, Papal Guards get the 'Pistol Attack' action, Papal Lancers get the 'Lance Charge' action and Papal Zouaves get the 'Carbine Attack' action
Aesthetically, the Papal Bombard is similar to the Li'l Bombard, although the Papal Bombard is brass-colored as compared to the black cast-iron of the Li'l Bombard. The crew use the same Papal Zouave models.
When hovering the cursor over a Papal Bombard, the description of it reads "Holy moly!"
The picture used to depict the Holy Fire ability for Papal Bombards is a cannonball with the papal tiara on it, the papal tiara being the crown worn by the Pope as a symbol of his spiritual and secular authority over Latin Christendom.
