I did not play for a demon for a while. But started a new playthrough recently and found a lot of changes. WIKI is pretty obsoleted so I have a few questions.

Now we have cultists and thralls instead of just thralls. It is good, I don't need to manage hundreds of hooks. But did cultist perk makes person infertile? I made full court of mortals, feys, werewolfs trying to posses a pregnant woman and get a childe, but i have not seen a single kid of them for 150 years. They have some children before getting cultist state, but not after.

Now I can posses any person in a court, which makes thralls even more senseless. But all my possessed vessels die in a year. I have a perk to reduce chance of dying, but it still 95% for any potential vessel. Description says that this chance is based on your "Torment". What is "Torment"? I have not found this stat anywhere.

I unlocked whole Arcana tree but I still can't enter Umbra. I can hire ambassadors, create wights, but I do not have button to enter myself. Demons should have easy access to underworld and spirit world. But I can't find it. How I can do it?

When I play as Fallen - I just a free spirit and I must possess someone every year to be active. When I play as Earthbound to Title - I am a lurking spirit in a castle/ruins. I do not have body, I can't travel or lead armies, my throne is always empty, half of my Arcana perks are useless, but I do not need to worry about constant looking for a vessel. I still can possess someone when I needed but most of a time I am fine without it. But when I Earthbound to Artifact - I can do everything. I can travel, lead armies, receive petitions in a court, meditate in seclusion... And all of this without possessing. How I can do that? Someone carrying my artifact? I have my own body? It is pretty OP comparing to other types.
