With Arkhan, the guardian of souls in Procession: Reikenor's Condemned and a general with Ruler of the Spirit Hosts the healing will be amazing. So far I think its legal until the new edition. Nighthaunt really needs more sub-factions. I did not look but I wonder if Nighthaunt is the only army book without sub-factions. Since the Bel'akor book, I want to play more my lovely ghosts.
