Um... I can't use the book again... I keep trying and nothing's happened since I got the "You learn the basics of the ancient language" message... And I've gotten my skill to a lighter blue (one swirly)...
Edit: I keep getting the message "The things written here, you know already."
A. You need to change your counter to the right page: 1, 2, 3 or 4. B. You have to be COMPLETELY uncapped, this is why you have to wait an hour. Reading caps you.
Well the amount of skill gained from a book can only reach 60 total for any intelligence. 15 per page. Anything else higher intelligence will make you learn faster i beleive.
