Proof of Progress

You actually get your 60/60 Elite skill from the quest, , not from this book. If you do NOT use the book at 60/60 and save it 'til you reach 70/70, you can read this book and get your 70/70 skill from it instead of the 70/70 quest. This can be done from anywhere in the world, no travel required, and grants your level 70 Elite skill for both your Primary and Secondary class.
This is considered an EXPLOIT and should not be discussed on the forums or the official RoM Discord chat. The ONLY reason I mention it here is that, as a solitary player it is very difficult to complete this task as intended.
