So, keep a close eye on how your neighbors view your religion, and be careful when converting to a heresy that will be seen as Hostile to any nearby rivals. It would carry such a large opinion penalty that itвЂ™s very difficult for groups that view each other as Evil to ever coexist.Д®ach step in the intolerant direction will give you an increasing opinion penalty with other rulers of that faith, and increase the amount of unrest in counties where the people follow it.

Evil: One step beyond Hostile, including differences as wide as Christianity versus Islam, with no intermarriage allowed.

While followers of these faiths can still marry, they have significant mutual opinion penalties, can declare holy wars against each other, and will be valid targets against which you'll need to seek the aid of Holy Orders like the Knights Templar and the Assassins. This includes how Catholics see Christian heresies like Catharism, the relationship between different pagan traditions, and the conflict between Sunni and Shia Islam.

Hostile: Faiths that are in your religious group, but are seen by you as heretical or dangerous.

This is the relationship between Catholic and Eastern Orthodox Christianity-there will be some friction between them, but not loads.

Astray: Faiths that are similar to yours, but not exactly considered to be heretical.

For example, there are multiple schools of Sunni Islam, but as long as everyone in the room is Sunni, they should get along fine. How different religious groups view each otherД®very faith in Crusader Kings 3 views every other faith in the world one of four ways: ThatвЂ™s key, because if not enough of them are convinced, you may have a sectarian civil war on your hands. Your own characterвЂ™s Learning stat will affect not just how much Piety you get per month, but also how likely your vassals are to convert to the new faith after you found it. You can squeeze out even more by marrying someone with a high Learning stat and setting them to the Patronage spouse job, and by making sure your realm priest has a very high Learning stat if you belong to a religion that allows you to appoint one yourself.

You should also keep the Theology character focus active for the additional monthly piety. This cuts the Piety cost of creating a new faith in half, which makes it far more realistically attainable. If that's you, first pick up the Prophet perk from the Theologian tree in the Learning lifestyle.

The thing is, this costs a lot of Piety-more than you can realistically expect to earn in a single characterвЂ™s lifetime unless you're really trying. One of the coolest new features in Crusader Kings 3 is the ability to create a custom heresy of your parent religion (or reform into an organized faith if youвЂ™re starting as a tribal pagan).
