Craft (Mechanical) (Int) Trained Only

This skill allows a character to build mechanical devices from scratch, including engines and engine parts, weapons, armor, and other gadgets. When building a mechanical device from scratch, the character describes the kind of device he or she wants to construct; then the Gamemaster decides if the device is simple, moderate, complex, or advanced compared to current technology.

Type of Scratch-Built Mechanical Device (Examples)	Purchase DC	Craft DC	Time
Simple (tripwire trap)	5	15	1 hr
Moderate (engine component, light armor)	12	20	12 hr.
Complex (automobile engine, 9mm autoloader handgun)	16	25	24 hr.
Advanced (jet engine)	20	30	60 hr.

Special: A character without a mechanical tool kit takes a –4 penalty on Craft (mechanical) checks.

A character with the Builder feat gets a +2 bonus on all Craft (mechanical) checks.
