Purificationer (5e Equipment)
From D&D Wiki
A purificationer is a magical cannon which has been blessed by divine magic to be more accurate, more durable, and capable of delivering a destructive blast of holy power whenever it strikes an evil being. Before it can be fired, the cannon must be loaded and aimed. It takes one action to load the weapon, one action to aim it, and one action to fire it.
Holy Cannon Ball: Ranged Weapon Attack: +9 to hit, range 600/2,400 ft., one target. Hit: 44 (8d10) bludgeoning damage, plus 44 (8d10) radiant damage if the target is an undead or a fiend. This attack is magical.
