Drill Bots (5.5) by

Drill bots have large cylindrical bodies and circular heads with a single large, glowing gemstone for an eye. They move around on four legs on their undersides, and wield two large drills in two arms. They are commonly made of either tough metals or stone.

**Faulty Programming.** The drill bots are so focused on their tasks that if something interrupts them, they are designed to remove the obstruction. This programming unintentionally causes drill bots to be violent when their tasks are not yet fulfilled, making them hazardous to work around. However, manufacturers of drill bots have decided that because the drill bots *work*, they don't need to waste time fixing this issue.

**Size Models.** There are two drastically different sizes of drill bots, the Miniature and Behemoth, meant for precision and broad drilling respectively. The miniature drill bots are much cheaper to produce and as a result are more common, while the behemoth is only rarely found in active use, especially after the drill bot's faulty programming was discovered.
