- With vendor in the end of time (after TP, left and first portal on left) you can buy at refresh of vendor (each lvl) 2 books for 10000 gold each, who give you 1 attribute point and other give +3 skill point. It is totally over power, you lvl give you 1 attribute point or 1-3 skill point and book give you 1 attribute + 3 skill at all Lvl
I think it works as intended. When playing normally, not rushing to find star stones, you'll get the room with Teller of Secrets at lvl ~12. Books refresh on lvl up, you'll get ~8 more levels, so with 4-people party, you will have additional 2 attribute points and 6 ability points from books on every char. Not really overpowered. Of course you can give all books to one char, but it also have downsides. Rest of the team will be weaker, and when your superhuman get cc'ed, you'll have a problem.
