I also think of more and more allies options and already purchased the Start Collecting Malignants, Skeletons and Flesh Eaters. Beside the Coven Throne, I think Arkhan, all forms of Vampire Lords as well as Vargheists seem to be good options. So far I tried a Vampire on foot and will give Arkhan followed by the Coven Throne a try.
I would love to field a Terrorgheist but am I correct that I would lose all Allegiance Abilities of Nighthaunts and could just use the Death Abilities from the Core Book?
I feel my Nighthaunts pull me more and more into Legions of Nagash (already purchased that army book, too). So many options ?
