It's as if they took a chainsaw and put wheels on it. It's intimidating but fortunately it's only supposed to be used to dig deep trenches.

The Luna-Tesla Corporation's attempts to expand their fiber optic network requires many trenches dug out. Naturally the most logical solution is to take a chainsaw to the earth itself. Groovy.

Heine-1830 Autonomous Chain Trenchers typically come in warning yellow or utility green. Though they are capable of operating on their own, there are often at least one operation nearby. Perhaps to ensure it's chewing into the ground and not into anything else.


Autonomous chain trenchers are not supposed to be used for combat, but they are very effective weapons. And why not; they are giant chainsaws. How is that not terrifying?

Chainsaw (Ex): Autonomous chain trenchers have a powerful chainsaw on front which it dips into the ground to dig deep trenches. It is adamantium, and bypasses hardness up to 20. As a standard action it does 4d6 + it's Strength, but if it takes a full attack action it can make a single attack and deal three times as much damage (including Strength). For the purposes of trench digging, it typically digs a trench 10 ft long a round up to 10 ft deep in any material it bypasses the hardness of.

Programming: The autonomous chain trencher possesses the following programs: Mimic, Reposition, Search.

Stability (Ex): Autonomous chain trenchers have stability as a dwarf, gaining a +4 bonus.


Heine-1830 Autonomous Chain Trenchers are build out of a composite of many different metals, plastics, and alloys which must be processed in a factory. In addition its computer core requires special components and programming. The cost of the base material components are worth 3600 gp.

Assembling the body requires a DC 24 Craft (technology) check, a DC 24 Knowledge Engineering, or a DC 24 Knowledge Xeno check.

CL 11th; Craft Construct, lesser geas, passwall; Price 34,000 gp; Cost 15,300 gp + 1224 XP.
