EOTN: Dungeon Books (Any reason to have them?)

The book is also a handy checklist of which dungeons you have done. That was basically what I used mine for. I maxed all my other titles by doing VQs and farming with a few speed books to finish em off. Dwarven was the last and I mxed that one by going through my dungeon books (HM first as I generally did dungeon ZBs in HM). They're a great way to keep track of that part of your Master of the North title and yeah, the rep for turning in a HM one isn't too shabby either. I never finished my NM book but got LMotN, couldn't turn it in as my rep was too high and had to trash it. But it was still an easier indicator than scrolling all over the map trying to find the dungeons I hadn't done.
