After the new patch, I decided to re-attempt my Slut Queen of England plan. For those who don't know, my plan was to create a custom female ruler in place of the King of England just 3 months after the start of the high Middle Ages. I decided to focus on intrigue and seduction and use that to get all of my vassals' opinions of me up. This time, I took the wounded, (I think ill, but can't quite remember if that was an option.) stressed, and depressed traits, and used the points I recieved to make the character attractive and give her 30 intrigue, 7.1 health, and 80% fertility. I also made her religion Cathar and decided to make all of England Cathar and make this heresy the true Catholic faith if possible.
Anyway, after roughly 30 years of rule, I've conquered all of England, Wales, and 2 Catholic holy sites. In 30 years I've screwed up history so much that England is Cathar, Rome is Cathar, the true Pope is in exile, multiple Anti-Popes exist, albeit no Cathar, everyone in England has STDs (Slut Queen indeed), England has more or less an equal society for men and women, and the first crusade wasn't for Rome or Jerusalem, but for England(and failed)!
Currently, I'm struggling with the making Cathar the true faith portion of the plan. I've fabricated claims on a third holy site held by a King of only 3 counties. The moral authority is around 36%, if I remember correctly off of the top of my head. I remember reading that it was possible on the CKII wiki, but I don't see how to do so. Unfortunetly, Cathar cannot make an anti-Pope because they reject the Papacy because of its corruption.
