So you buy books at a temple start reading them in Camp and wait quite a wile for them to finish.
But the book price has quite some variation and there are a lot of books.

So i was wondering what Type of book does what exactly? i heard some give exp, and some give focus points. But which book does what? Will a focus point still be rewarded if i already put 5 into that skill? Are Books that give focus points uniques or is it possible to get multiple points in one skill from different books?
