I chose to include the Iron Lich because it fits the mod, but also has always been very scary to me. I could raise the amount of XP it gives, I suppose.
Speaking of monsters, are there any others from Realm 667 you'd like to see included? I do intend to make a couple more from Daggerfall myself, but that's very time consuming, so I'm in no rush.
I'm off Wednesday, and so can do some tweaking if necessary.
Keep the comments/suggestions comin'!
