Book of Secrets

Appologies if there is already a thread regarding this, I couldnt fint one.

I've done abaddon's gate now 3 times. first time i got the book no problems there, didnt fancy any of the weapons, so i just kept the book.

Second time i completed the mission I did'nt get the book, I assumed it was because i had one already in my inventory, so i exchanged it for a weapon.

Third time, Again I did Not get the book, ?? Is it that you are only allowed 1 book per char.? feeling kinda ripped off. as i had planned to kit out my best heros with end game greens, but dos'nt look like I will be able to.
Anyway,,,,Is this how it's supposed to be?????

It's one per character, just like in Factions.

thanx,
, I neved bothered completing factions so i never knew

Otwerwise the last mission would be over farmed.. The end game green has to be unique, thats why you one get 1 pr. character.. I also mean it's best that way
