Honestly, I think the minion system needs reworking. I mean, the Shadow Queen might have over a million succubi, but very few are going to be bringing in several souls a week. Unless she's running infernal brothels in every major city, you've got to imagine that it takes longer than a few hours or even a day to corrupt souls. AND, even if you do manage to corrupt a soul, you have to wait until that person dies.<br/><br/>Maybe having several areas that minions could be put to work at: Soul Harvesting, Material Plane Influence, Outer Plane Influence, Blood War Influence, Occult Studies.<br/><br/>Certain minions get a bonus to certain things. A succubus is going to be better at Soul Harvesting and Material Plane influence than a Balor, but be worse at influencing the Blood War or Occult Studies.
