Mechanical repair (Call of Cthulhu 7th Edition)

Skills

Definition

Mechanical Repair represents your ability to fix, build, and understand mechanical devices—engines, clockwork, tools, weapons, and any non-electrical machinery. In the 1920s, the world runs on mechanical technology, making this skill broadly useful. From repairing a broken-down automobile in the middle of nowhere to rigging a makeshift trap, Mechanical Repair keeps equipment working and creates solutions from available materials. In Mythos investigations, mechanical devices often need repairs after encounters—doors ripped from hinges, vehicles damaged during chases, and equipment broken during panicked escapes.

How it works

**Base Value**: 10% **Key Uses**: - Repairing mechanical devices and engines - Building simple mechanical contraptions - Understanding how machinery works - Creating improvised tools or traps **Special Rules**: Mechanical Repair covers non-electrical machinery. Electrical devices use Electrical Repair. Repairs require appropriate tools and parts—improvisation is possible but harder. Time depends on the complexity of the repair.

Tips

**Build Advice**: Very practical skill that comes up regularly. Especially important if your group relies on vehicles or mechanical equipment. **Occupation Synergies**: Pairs with Drive Auto for keeping vehicles running, Operate Heavy Machinery for industrial equipment, and Locksmith for understanding mechanical security. **Character Concepts**: Mechanic, engineer, handyman, farmer, chauffeur, inventor, tinkerer.

Frequently asked questions

What's the difference between Mechanical and Electrical Repair?

Mechanical Repair covers physical, moving-parts machinery—engines, locks, clockwork, plumbing. Electrical Repair covers wired systems—lights, radios, telephones, electrical alarms. Some devices may require both.

Can I build things with Mechanical Repair?

Yes, simple mechanical devices, traps, and modifications. The complexity determines the difficulty. Building a basic snare is easier than constructing a working engine from scrap.
