been getting alot of stuff that when examined tells you that they can be studied to learn more about the mob they dropped off of...is this just junk? can i sell it? whats it for exactly???
You buy a book from certain merchants that are books about mob lore. You then examine the items (usually 12 or so to a quest) and you are rewarded a special attack towards that family of mob (like a sneak attack for scouts, a spell for mages, etc). Pretty nifty, pretty hard to obtain.
I heard the special attacks were taken out. But when you buy the books from the vendors and complete your "collections" you get quest rewards, xp, items, etc.
After reading the book you are offered a quest. After accepting the quest, upon examining the items, you can "add it to your collection".
