Lathel found a lot of books; however, there were two methods to read books in this place.
Either by using contribution points or gold coins. To get contribution points, you need to complete Enchanter Tower missions.
Depending on the rarity of the book, the contribution points you need to pay will be higher.
If you use gold coins, the amount of gold coins you need to pay will be 10 times higher than the contribution points.
Lathel found a book about earth magic. Although this book has a very low rarity, it still requires 10 contribution points to be able to read it.
10 contribution points are equivalent to 100 gold coins. So... if he looks at more advanced books, the amount of gold coins he needs to pay will be very large.
'Looks like… I need to take on some Enchanter Tower quests. Otherwise, I will be poor from reading books.'
'Fortunately, I still have a lot of gold coins left; otherwise, I'm afraid I can only look at a few books.'
