Regarding Mastery books and stuff.

Well, let's see... All I need to know is if anyone knows an up-to-date list of where to find mastery books.

Well, mainly, I'm looking after taunt 30 (I mean,is it still only GPQ bonus?). And also the other thief skills :p

Anyone knows where can I know?

I think taunt 30 came from gachapon boxes too, but for now I'm pretty sure it's gpq bonus only unless one of the malaysia monsters drop it or something.

Basil's drop list seems pretty much up to date with ToT, although obviously I can't guarantee it's perfect.
