As for the tome, we’ve also changed the description internally to make this clearer and changed the actual usage level to 20, but in the meantime, here’s the info:
The Tome of Destiny +1 (Feywild) requires your character to be in a state where they can make changes to their Epic Destinies. This means that you must be level 20 or above, AND either be talking to a Fatespinner or VIP (who can edit their Destinies anywhere outside of a dungeon). If you’re having trouble consuming the tome, talking to the Fatespinner will kick things into gear for you and hopefully let you read it in peace. If you still can’t get it to apply, please let us know ASAP so we can continue investigating.
