I know the Styg and Afel are currently trader only, Boltgun is still doing the method to make them on site, but I think it only says that in his vanilla succubus thread, so you wouldn't know unless you read both threads.
Migration is supposed to stop? It seems to follow your pop settings just fine.
Migrations waves are intended, it might stop if you set the civ as evil as you'll get no export values.
I should have told about the metals but I replied on reddit for clarifications.
I tried to summon a fell spirit via portal, which requires a bronze cage, rose gold and slade slabs, but it still showed the slabs red although they were in a stockpile right next to the summoning portal.
Did you setup burrows? There is bugs with those that prevent items to be properly selected. The next DF version will probably fix that.
Tentacle monsters, spirits of fire and fell spirits all share the key shortcut [t] in the summoning portal.
Will fix that asap.
Frog demons and decay brutes show up as 'citizens' in Dwarf Therapist. Some of the frog demons look as if the could haul items in DT but most have any work disabled. It doesn't seem to depend on them being children or adults or what profession they have.
They re treated with intelligence by DT even if they shouldn't. I'll try to make them truly intelligent next patch and make them haulers.
I can turn human visitors in the tavern into devils with the Den of Inquiry. They don't become part of my civilisation - BUT if I accepted them as temporary citizens into my militia first they suddenly have all their jobs enabled. This seems to be a nice and quick way to generate some cheap human haulers who can also swing an axe. I like! =3
Maybe the other visitors should also become proper citizens for consistency?
It's great and I am surprised that it work at all for citizens as it was designed for invaders. Corruption will be reworked in the near future.
Currently I'm on an embark with nagas, goblins and orcs as neighbors and they are all at peace with me. If it wasn't for the occasional werebeast or living stone I'd have no fights at all. Would it be possible to bump the hate factor for succubi up during world gen to get more enemies?
I cannot do that, you must embark with hostile neighbors. Activating invaders for your world will provide some proper chaos.
By the way, I streamed some df yesterday and TWBT crashed on me. A lot.
