“Sounds like you dropped your book of masteries somewhere”
I got the book in my backpack, masterie activated
“What client? And what’s the exact system message?
is the book in the top level of your backpack? Or in a spell book strap?
try dropping the mastery book on the floor and picking it up again”
Ok. I ve bought a new book of masteries from vendor search and now is working. So u need a new book per char? u cant reuse them? puiff
“Doesn’t sound right to me, I’ll check it out later”
I've had that happen a few times and it always ended up that the reason was as Keven stated. I had the old Book of Masteries in my pack.
I think if you were to single click the book and select "Switch Mastery" that would update it to 45 spells.
