Hellfire Engine

D&D 2024 monster: Hellfire Engine. Source: Mordenkainen Presents: Monsters of the Multiverse. challenge rating 16, creature type Construct, Huge size, speed... Hellfire engines are semiautonomous bringers of destruction. Amnizus (in this book) and other devilish generals hold them in reserve until they are needed to repel an incursion by demons or crusading mortals, but occasionally one of these magical-mechanical hybrids gets loose, driven berserk by its need to destroy. Hellfire engines take many forms, but all of them have one purpose: to mow down foes in waves. They are incapable of subtlety or trickery, but their destructive capability is immense. Mortal creatures slain by hellfire engines are doomed to join the infernal legions in mere hours unless powerful magic-wielders intervene on their behalf. The archdukes of the Nine Hells would like nothing better than to modify this magic so it works against demons, too, but that discovery has eluded them so far. Construct Huge 40 ft.
