Possible to create Incestious family?
I’ve given my Ruler the incestious trait but I can not find other people who have that trait. The dream would be to have my whole family sleeping with eachother. Any tips? And does the incestious trait have a chance to pass down onto my offspring? And is it possible to torture my kids while sleeping with them at the same? Thanks

Ahem. Murky moral issues aside, the incestuous trait is not a perquisite to seduce your family members. However, seduction and/or marriage with your close family are extremely difficult if your religion does not have the unrestricted marriage doctrine. AFAIK, only two Christian faiths (Messalianism and Adamitism) and two Zoroastrianism faiths (Mazdayasna and Zurvanism) have this trait. You'd need to convert yourself and your family to one these four faiths or to a custom faith with this doctrine. Otherwise seduction attempts would usually fail and marriage is not possible.
I believe you can probably torture your lovers, although I haven't tested this theory. I once slept with the pope in order to prevent him from declaring a crusade against me. It didn't work, and I defeated him without ending the affair.

Also, while conversion solves the marriage restriction, it does not remove all the penalty for ex-marital seduction attempts. You need the intrigue perk "Subtle Desire" from the seduction tree for that.

Trolling or not, to clear this up:

The "Incestous" trait is only a branding for shunned / criminal activities within your faith, same like Adulterer or Kinslayer. It gives a +20 opinion bonus with other incestous characters, but this is just an offset for the -15 opinion penalty which other characters have towards you.

If an incestous marriage relation would illegal under your faith doctrines, there are only three ways to become lovers regardless:

A) Intrigue - Seduction focus - Subtle Desire (target needs to be 20+ years old, and the player can always accept if being seduced by an NPC family member)

B) Seducer is a human player, and the target is arbitrary (no matter what the seduction chance says, it will always fail otherwise, unless the target is arbitrary or you have the subtle desire perk)

C) Extremely rare event where a ruler can fall in love with a random close relative. The player can always choose to accept or refuse, and the AI target can never refuse. If the initiator is an NPC then both are more likely to refuse.
The chance for the event to happen increases if both characters have matching traits, and if the target is landed or married to a landed character in the same realm. Yet i've only seen this once in hundreds of hours.



Note that the incest lovers were an absolute chaos after the game release. I constantly caught family members, like the son having an affair with his mother. Also you regularily had feast events to become romantic with close relatives. There even was a bug which allowed you to take any courtier as concubine.

This has all been fixed & nerfed, getting frisky with close family only works as described above, or changing to a faith which legalizes it (not recommended).

Thanks for the great answers.

When I add the filter Incestious trait as the only requirement for my future spouse, I get no results at all :(

This is a fame trait, and not that meaningful or common. You could probably get it just if you're caught in the act and your religion forbid incest. But if your religion forbid incest you'd have hard time committing anything that get you caught..

Look, I'm not here to judge anyone by how they play CK3, bur.......

I wouldn't try for that trait specifically but would just form a custom religion that has unrestricted marriages then start breeding siblings and parents ^^

Yeah, it was a bit of a surprise for me when playing the game and my daughter tried seducing me, and I just married her with a matrilineal marriage to bring a guy with 19 diplomacy to my court so I could have a great chancellor.

incest and ck go hand in hand

I've always wondered why certain social taboos are casually flaunted in videogames like violence and incest but some wouldn't be touched with a 10 foot pole (racism, sexism, etc). I think it shows society's morals are indeed relativistic.

Just keep in mind it may not turn out the way you envision it. It isn't Game Of Thrones, where Targaryen incest seemed to only spawn super attractive men and women with white hair. You go the incest route, you're looking at your family being mostly Lord farquaads in a few generations.

It can be bad, but it can also give you a buff.

I married my daughter and my 3 sisters are my incubants and I'm following the blood line research tree thingy.

Ahh, sleeping with the pope. I once had the pope as my lover. Got her* pregnant, ended the love affair and blackmailed her afterwards. Got me the "have a strong hook on the pope" achievement.

*Yes, her. Had my own religion which allowed for female rulers. And also incest, which was quite important because I was after the "Perfect cylce" achievement. Which I indeed got in the end.

Ahhh, what a game...

I'm after "A Perfect Circle" right now. Got any tips? I don't have religion problems, only micromanagement problem. I need a ruler young enough to arrange the marriage of his children, but those are usually not elected in the early game...

First thing is to have a religion that allows or even promotes marriages between siblings, but you seem to have managed that. Also try to have many positive traits (especially "Genius") already within your line to offset the negative traits from inbreeding. It also helps to have the dynasty perks that increase the chance of positive traits.

Then hope for enough children from both sexes and betroth them to each other right after birth. Have your spymaster looking for secrets in your own court a lot to identify possible bastards.

Also save enough fame to be able to disinherit
- children that you suspect of being a bastard
- chldren that are sterile / barren
- and children that have spouses who are not sibblings.

And then have patience...it takes longer than you might think.
