For forging letters.
Ability Score(s): Precision + Language
Usage: Forging letters and signatures. In order to detect a forgery, a Language (Read) check must be used or a similarly related skill. Example; a forgery of a law document can use Law with Language (Read) as an exchange instead. Language (Read) must be required in order to read if the letter is a forgery and the Read skill must relate to the language in the script.
While one does not require Language (Write) in order to attempt to make a forgery, making a forgery without understanding the language is done at a -20 to the check.
