I find Vaetti hags to be of exceptional value when playing Jotunheim. They cost 55 gold, get a random pick in sorcery, and are stealthy. They're efficient researchers, and you can do all sorts of useful stuff with their magic pick. Astral ones can cast arcane probing and act as communions slaves. Death ones can cast dark knowledge and reanimate dead. Nature ones can forge some handy items, and blood ones can go hunting.
