- Augmetics (Restricted): Studied in the use and repair of different types of augmetic devices. Most augmetics are mechanical or electrical augmetic substitutes for Human biological parts, many with enhanced capacities, though some offer entirely new capabilities. Augmetics requires at least 1 Advance in the Medicae (INT) Skill.
- Engineering: Knowledge of the construction, use, and restoration of technological and mechanical devices. Encompasses the crafting of such items, as well as weapons and explosives. Within the Imperium, the Adeptus Mechanicus considers this entire branch of knowledge to be their exclusive right and will punish those who use it, or even study it, without their sanction. Notably, an individual that knows only how to assemble or repair a device by rote need not have this skill.
- Security: Knowledge of how to interact with the Machine Spirits that control security devices, along with whatever other systems have been linked to the same, such as doors, thermo-regulators, weapons systems, and so forth, in order to direct them in specific ways. Accomplished through the use of binary codes, modern and ancient, along with various techniques used to sift information from datavaults, secured or otherwise. A skill known to few outside the Adeptus Mechanicus.
Tech is a measure of a character’s ability to use and repair technological devices. Within the Imperium of Man, this falls squarely under the purview of the Adeptus Mechanicus. In spite of this, people outside that order can acquire a knack for using, repairing, and even modifying technologies. Those within criminal cartels, on Feral Worlds, or in areas without proper Mechanicus access are among such individuals, though they will likely never match the expertise and knowledge of the rote (but often quite effective) techniques of an actual Tech-Priest.
