Mastery Book Drop List

I really like this one https://ayumilovemaple.wordpress.com/tag/skill-book-drop-list/ It's not complete but I have found it very accurate.

Some areas are not included like ToT and maybe Ulu city.

 

Ulu City has no mobs that drop Mastery Books

 

The boss drops books and i don't think it's mentioned in the link, but good to know i never farmed in Ulu and wasn't sure if mobs dropped any.

 

Are the books mentioned here correct? If so, I have to update my own guide...

 

I take that back, I believe Petrifighters drop books.

 

I can't confirm all books, but it's very accurate.

 

how about barrage 20 what mob drop it?
