I have had the weirdest luck with the books. First time out I was playing with Shadow wyrms Daemons, evil mage lords, drakes and wyverns second level Destard Tram and got five books in the first hour, then nothing for two more hours. Went to Acid elementals for an hour and got two books, then nothing for next hour there. Moved over to Ogre lords for THREE hours and got no books. Few days later went to Ogre lords again and got a book on the second OL but then nothing for an hour and a half. Went to Hycloth daemons and got one from the third daemon and then nothing for over an hour. Then to covetous Drake/dragon spawn and got a book off the fifth drake and then nohting for an hour. I am only wanting the pritty (but slow) sword for if I ever long term camp Doom.
