Characters mostly have some logic to their decision-making, but it's probably hard to think rationally when there's a demon standing next to you, demanding your soul ;) But I'll see if it's possible to improve the algorithms here. Similarly with selling your soul - this is something that shouldn't happen often with AI characters.
If you have combat magic trained and a few magic items and full Power Saturation, you have a good chance with most demons - just watch out for those with full magic protection (demon princes).

Yeah i like that it happened tho now i know not to train ambitious characters since that trait gives u that option{i think} its a big waste especially if they die before teaching there there hiers magic.
I used the Lycon and Vampire mod for that playthrough so it gave sum family members enough time to get the True witch and mage trait ;] eventually i had about 10 plus True Witches in my Dynasty and my magic sense went off every once in a whie lol

My 2nd Mage character Grim made it to 150 plus years old due to my lilith lover defending me from dozens of murder attempts but the filthy demon had to go after she gave me 2 none saturation children and mostly bcz she murdered my mage dynasty member and our beloved mage baron who use to mage duel Grim's father Gandolf the mage[badass nickname from destroying a witch hunter lol] i was ok with her killing a normal family member but mages......no shes gone far enough. but Grim with lvl 2 knowledge and lvl 3 combat i could destroy any minor demon nd any mage that crossed me easily. although one dynasty member beat me due to low Saturation but luckily spared me bcz im so awesome lol

i got over confident and chellenged Baba Yaga i thought i could take her with my Artifact but after 2 battle roles i fell into depression knowing my chad of a character was eventually about to die so after i got destroyed i reloaded bcz i didnt want to lose my magic artifacts and took the decision to pass to the other world to be fair {i hoped he would come back more powerful or something crazy lol] but i prepared a son with the saturation trait nd high prowess so i wasnt too sad since my magic power could regenerate faster and that meant more magic duels with demons, foreign mages and dynasty members ofcourse he had the lycon trait so i had enough time to build hin up again and learn more spells from that magic book [hoped he learned the heal spell like Grim but didnt lol]

My dynasty is of the reformed Tumeric religion which made it easier for vassals and dynasty members to like me bcz this religion loves witches so eventually my entire empire became witches and we all "MOSTLY" getting along. i also befriended this minor demon for fun and granted him land since i love high prowess characters for knight but he started killing my family member i was ok with it until he killed a true witch dynasty member so i killed him with magic for insulting my kindness and replaced him with my friend who is a mage he will make a way better vassal
Oh and my head of faith is a mage taught by myself but due to his traits he never wants to mage duel me :( his a vassal of myn for safety reasons ofcourse cant struggle to groom another perfect head of faith :)

as u can see really enjoying ya mod cant wait to start another playthrough with the new update
;)

:D
You're a harsh ruler, but I see you making good use of mage duels :D I like this approach: don't mess with my dynasty (or at least the witchy part of it ;) )
I think you will have more opportunities for duels :>
BTW You can also learn spells from Hecate (while summoning) or if you have Academy of Magic (place of power).

yeah i didnt dwell too much into the places of power until later will do next time tho the bonuses are way too juicy magic wise and ill get the magic rulership for the reduced teach sorcery bonus lol
i can see that lol AI does give me violent nicknames nd i do LOVE the Sadistic trait hehe but i mean it aint that harsh i even let em (the demons) off the hook a few time especially that lilith bcz she was my spy master with that high intrigue lol and besides they demons not humans its like killing a wild animal that harmed u first no biggie
;)

yeah i do love the mage duels. I was so proud when my Giant son that got his soul taken Lance achieved lvl1 ancient knowledge i bet its rare for AI to do that huh lol (again he was like 112 yrs old or sum before he died so he had time) nd almost lvl2 combat due to all the duels we had BEAST!!! {sad he died but atleast he" teach sorcery" to his hier before he died} but his hier anyways died shortly after in a mage duel to a random AI mage but fair play he died in a mage duel atleast went out like a true unexplained dynasty member!!!
i couldnt get my revenge sadly since he died in a war before we could magic duel :(

CK allows you to create great stories :) I perceive a high level of role play here :D But something tells me that I wouldn't want to be your courtier... ;p

My dream heir with source just got murdered by Baba Yaga at his own grand wedding :| I have to be careful who I invite to weddings.

I wonder if to increase the acquisition of secret knowledge a little. 112 years is quite a lot, although AI actually earns XP poorly. I'm not sure if all the bonuses apply to them.

That sucks those hiers as so rare nd hard to get nd its not like u can do much to her aswell shes OP lol

I cant remember the exact age he reached lvl 1 knowledge 112 yrs or abit older was the age he died but yeah maybe u can link it to them doing better with ancient knowledge if they have high learning,certain personality traits that makes it more likely to get exp throught decisions or if they did learning education in there youth.(quality of there learning eduaction trait can factor in)
That would Benifit my head of faith who is a mage alot since he doesnt like dueling due to his traits lol

Yup this mod is a role playing gold mine for sure!!!

Sometimes ♥♥♥♥ happens :P

Yaga is strong, but she should be so. Well, and it can be defeated, at least when you are a powerful mage.

I'm unlikely to use modifiers for secret knowledge, preferring some additional opportunities to acquire it. We'll see...
