Houfnice

Compared to a regular Bombard Cannon, the Houfnice has +10 hit points, +1 pierce armor, +10 melee damage, +0.2 tiles of blast radius (), +10 bonus damage , and , and +50 bonus damage vs. . The upgrade does cost a sizable , but it pays for itself quicker than it would seem, as Bombard Cannons are already costly. The Houfnice can take up to 23 fully upgraded Arbalester bolts, compared to 16 for a Bombard Cannon. It also has a 40% larger blast radius, making it more effective against mass infantry and foot archers. It flips the trade against Siege Onagers, which kills the Houfnice in two shots (one shot if 4–5 extra Siege Onager projectiles hit the Houfnice with an attack order (not attack ground), depending on Chemistry) but only needs one Houfnice shot to be killed (guaranteed on attack ground). It is the other way around for ordinary Bombard Cannons. Its higher pierce armor also means it takes 1 damage from fully upgraded Elite Skirmishers, rather than 2 damage like a Bombard Cannon would.
