A Path to Steam
Defaults: IQ-6 or Counterfeiting-2.
This is the ability to create falsified documents (identity cards, passports, etc.). It is not taught except by intelligence agencies and the underworld – although you can always study it on your own.
The time required to create a forgery ranges from days to weeks (GM decides). When you use a forged document, make your Forgery roll each time it is inspected – unless you roll a critical success on your first attempt. Failure means someone spots the forgery.
Some tasks require DX-based skill rolls, in which case modifiers for High Manual Dexterity (p. 59) or Ham-Fisted (p. 138) apply. The GM may allow Forgery to default to a suitable Artist specialty at -5 if you are doing the work entirely by hand.
Modifiers: Equipment modifiers (p. 345); +3 if you merely altered a genuine document; -5 if you did not have a sample to copy. The GM may also assign modifiers based on the severity of the inspection; a routine border check, for instance, would give a +5 bonus.
