These machines came in numerous shapes, but they all had in common their purpose and immense destructive capacity.
As a hellfire engine moved through the battlefield, it could crush and trap creatures under its weight. In addition, it had a variety of weapons, such as an acid sprayer, a lightning-infused flail, and a cannon that fired an explosive shell.
If mortals were slain by a hellfire engine, their souls were doomed to join the ranks of the devils in the form of lemures within hours. If the transformation was allowed to run its course, only a wish or true resurrection spell after killing the lemure could restore the soul.
The devils were constantly modifying the design of the hellfire engine in order to increase its effectiveness. Their main topic of research involved improving its soul-converting ability so that it would also work on demons.
