So, I've been able to find warscrolls for the slaves of darkness units, but I could not find any points information or other stuff, like army special rules, artefacts, command traits, etc.
In order to use the Blades of Khorne rules I'd need to have only Khorne units, right? Are Slaves to Darkness effective/competitive? I'd love to have an undivided legion that's heavy into summoning and summons units of lesser demons and perhaps greater demons, but I wasn't sure if this was possible.
