Earthdawn - Who Really Kaers?
Read and Write Language
The adept learns to read and write different tongues and may learn a maximum number of languages equal to his Read/Write Language Rank. If he has an unassigned Read/Write Language Rank available, the adept can attempt to learn a new language by reading at least one page of text written in the language for at least one minute, then making a Read/Write Language Test against the language’s Learning Difficulty. If successful, he learns the language and notes it on his Character Record Sheet.
