Ok I am almost done with EOTN for the first time in NM. I have 13 of 16 pages complete. Once I complete the book I know I can turn it in for like 20k points.
From what I have read the best way to raise in rep rank is to turn in normal mode book at r7 and that will take up to or close to r9 in whichever rep.
So my question is do I need to hold onto my book until then? Or I turn the book in and I can get new NM books to redo?
Thanks in advance for your help.
