In play
Inbred: diplomacy falls by 5, martial falls by 5, stewardship falls by 5, intrigue falls by 5, learning falls by 5, prowess falls by 2, fertility falls by 50%, health falls by 1.5, attraction opinion falls by 30, and vassal opinion falls by 10. Inbred drags skills, prowess, fertility, health, attraction, and vassal opinion together. It is the marriage outcome a house avoids.
How to get Inbred
- Gain: Inbred appears on children of related parents (a shared ancestor within four generations) when a parent has a trait that enables inbreeding, such as Club-footed, Hunchbacked, Dwarf, Giant, Spindly, Scaly, Wheezing, Bleeder or Sterile; the chance rises with how closely related the parents are. An Inbred parent also passes it on 15% of the time, and a rare health event can make an existing inbreeding problem visible.
- Remove or lose: Permanent.
To avoid it, check both partners for inbreeding-enabling traits before a close-kin marriage, or marry Pure-blooded characters, whose inbreeding chance is halved. Unrelated parents never produce Inbred children except through inheritance from an Inbred parent.

Questions about Inbred
How do you avoid the Inbred trait in CK3?
Inbred needs related parents plus an inbreeding-enabling trait such as Club-footed, Dwarf or Sterile on a parent, or an Inbred parent who passes it on 15% of the time. Marry outside the family within four generations, or use Pure-blooded spouses, which halves the chance.
