I have completed the prologue, and bk4 and 5. I can not pick up bk6! Do youhave to have all the books completed before he will give you book 6? Does Grimbold give this to you? Do you have to be lvl 75? What the heck am i missing here! Im starting to feel like i am an idiot
You have to complete book 5 first because it is a continuation of the same story line. I won't spoil it, but there is something that happens in the end of book 5 which directly relates to book 6, and it would not make sense without it.
Also, you don't have to be level 75. I have started it at 73 on one of my toons.
