- Found in a secret passage down the elevator of the Surgery Altar that goes to the Research Hall Lamp when players have the Eye Pendant.
It has lower base damage than the cannon (480 base damage when fully upgraded, compared with the 600 of the Cannon), as well as lower QS Bullet consumption (only 10 instead of 12). It also has a slightly lower strength requirement, but a higher Bloodtinge requirement.
There is an arc to its shot, which explodes only upon impact instead of exploding in mid-air. The Church Cannon also reloads faster than the regular Cannon.
- The Church Cannon actually has an explosion and arc, making it more similar to a grenade launcher than an actual Cannon. However, because its projectile can only explode once it hits a surface, it has, in theory, much better range than the Cannon.
- Used by a variant of the Nightmare Executioner.
- It has the distinct design of firearms produced by the Healing Church, with its gold and silver colors and the wheel handle. Much like the Repeating Pistol and Ludwig's Rifle.
