Mechanics

Assembly, gunsmithing, and cybernetic installation.

Mechanics is the hands-on, grease-under-the-nails craft of making things work better. It covers gunsmithing (tuning a slug pistol for tighter groupings), cybernetic implantation (the surgical side, with Medicine support), field- stripping and reassembling devices under pressure, and calibrating systems to peak performance. In the verse, a good Mechanic is the difference between a weapon that jams on the third shot and one that fires clean through a sand storm. Rim crews prize them as much as pilots -- you can't fix a reactor with a blueprint alone. Field repairs in combat use Repair; Mechanics is for the workbench and the clinic.

Notes

Special: A cybernetic implant requires a successful Mechanics check (DC varies by complexity) followed by a Medicine check to avoid rejection. The Cybernetic Adaptation feat grants two automatic successes.

Untrained: May attempt trivial assembly (replacing a battery, tightening a bolt). Gunsmithing, cybernetic installation, and complex modification are beyond untrained capability. No armour check penalty for untrained attempts.
