I've had it! I can't seem to keep track of where all the skillbooks that I need come from. So I spent a couple of hours tracking it all down and making a comprehensive list. The blog is really just my personal resource for a quick reference of stuff that I can't find anywhere else. It's organized according to how I play.
But it took so long, I just had to share it! I hope it helps you too!http://meandpwi.blogspot.ca/2016/05/blademaster-skill-books-how-to-obtain.html
