  • Antimagic Susceptibility. The driller is incapacitated while in the area of an antimagic field. If targeted by dispel magic, the driller must succeed on a Constitution saving throw against the caster’s spell save DC or fall unconscious for 1 minute.
  • False Appearance. While the driller remains motionless, it is indistinguishable from a normal driller.


  • Drill. Melee Weapon Attack: +9 to hit, reach 10 ft., one creature. Hit: The creature takes 42 (12d6) piercing damage and must succeed on a DC 17 Dexterity saving throw. Creatures failing their save are restrained until the beginning of the driller’s next turn, as they are pinned against the nearest surface.
  • Trample. The driller moves up to its full speed and may move through Large or smaller creatures. Creatures in the driller’s path take 22 (4d10) damage, or half with a successful DC 17 Dexterity saving throw.


This mechanical monstrosity grinds to life with industrial precision and deadly strength, a massive industrial engine brought to life by technomagical sorcery.

Construction Machines. An animated driller is crafted and programmed to perform simple tasks under the direction of its creator or a designated overseer (often another, more intelligent robot or construct) or follows a predetermined set of actions, destroying those who get in its way and ignoring those that do not. Animated drillers occasionally go out of control, however, as their programming breaks down, causing them to rampage destructively until destroyed or controlled.

Scientific Machines. A biologic processor collects, stores, and analyses tissue samples from living creatures brought to it, cataloging them for further research. Usually such tissue is helpless or dead when brought to the machine, but it fulfills its programming even if its “samples” resist and try to escape.
