I am going to be hammering that book hard this weekend. I have a lot of questions about the merged army list, because their two different types of magic don't really work on each other, and then there's the issue of the generals for the armies, heirophant, stuff like that. So many questions about how it actually works. I hope they put the effort into explaining those rules. It's not something that's a huge deal with other armies, but with Undead, it's a unique situation.
