I’m just a little confused by this. My friend upgraded his book with the same jewel that he has in the back piece he got from the personal story at level 80, yet when I tried to do the same with a Fine Transmutation Stone I got an error message, and crafting my own Exquisite Ruby didn’t let me put it in the book.
Did he get a lucky bug or did they change it recently so that it can’t be upgraded the same as the personal story back? It’s a bummer, I’d love to use the book, but I don’t want to give up that extra 3% crit damage.
