Dev Diary #21 - Custom Faiths and Pagan Reformation

Oh, hello there! Interested in becoming a heresiarch, are we? Or maybe you just want to organize your ancestor’s ancient spiritual traditions into a true reformed Faith, one that can stand up to the Crescent and Cross? Either way, you’ve come to the right place!

To start us off, I’m going to go into how the process of creating a new Faith or reforming a pagan one works. After that, there will be a teaser of some Tenets and Doctrines that you may be interested in picking for your newly-founded Faiths ;)

Faith Creation
Creating a new Faith is no easy task. Only the most pious rulers will be able to convince the clergy within their realm that they alone know the true will of the divine and, in doing so, take the first steps towards establishing a new Faith. However, with a little bit of devotion and a lot of time, you too will be able to reshape your Faith to suit your dynasty’s needs!

When looking at your own Faith’s tenets and doctrines, you will see a button at the bottom labeled ‘Create New Faith’. Clicking this button will open the Faith Creation window, which can be viewed at any time — even long before you have acquired the means to actually create a new Faith! This will allow you to play around with the different options and get a feel for what is possible, allowing you to set long-term goals for yourself.

You can change every single Tenet and Doctrine of your hypothetical new Faith on this screen, though the list of what Tenets are available to pick varies from Religion to Religion. For example, Tenets based on the concept of Dharma are exclusive to Oriental Religions, whereas Monasticism was common practice and is thus available to everyone. This means when creating a new Faith, you must first ensure you are a member of the Religion that you want to base your new Faith off of.

Beyond simple availability, it is also easier for some Religions to accept certain Doctrines than others. For example, Islam is used to polyamory and will happily accept a new Faith espousing it. In contrast, a new Christian faith that claims God intended us to have multiple spouses will be met with a little more skepticism...

The way this plays out in CK3 is that each Tenet and Doctrine has a Piety cost associated with it. The further you deviate from your original Faith, the more Piety you will need in order to convince the priests that yes, you actually have had a vision from the divine and yes, you actually are enforcing their will and not just trying to make some weird personal sex cult.

After you have made all the changes you want, you will be given the total amount of Piety your character needs in order to create their new Faith. This cost can get quite high, meaning that creating a new Faith or reforming a pagan one ends up being a life-long goal for most characters. It is highly recommended to attempt this with characters who have a Learning education and/or who have multiple Virtuous personality traits, and having the ability to go on frequent pilgrimages or donate gold & troops to holy causes helps too! Finally, timing your divine revelation to completely coincidentally occur when your Faith is suffering from low Fervor will make it much easier to get everyone to buy into your new canon (I will talk more about Fervor in our future Dev Diary on heresy outbreaks).

Once you are happy with your Tenets and Doctrines and have accumulated the necessary amount of Piety, you can officially convert to your new Faith. You and your capital county will adopt it immediately, but it won’t be easy for a ruler to convince their vassals and subjects to adopt this strange new Faith — they might be more inclined to stage an uprising and depose their mad king from the throne! After all, if you die before your new Faith gains a foothold in the world, there is a good chance your Faith will die with you…

Pagan Reformation
Pagan Faiths in Crusader Kings III start out with the special ‘Unreformed’ Doctrine.

This Doctrine grants notable bonuses to Tribal rulers early on, but it locks them into the Tribal government type and provides substantial Opinion penalties to any non-Tribal vassals they acquire. Since Tribal realms are notoriously unstable, successful chieftains will eventually want to look into either converting to a reformed religion so they can feudalize, or reforming their pagan religion into a true organized faith.

Like with Faith Creation, rulers must earn a substantial amount of Piety to organize their Faith’s disparate shamans into a coherent clergy. In addition, they must have at least 3 of their Faith’s holy sites located within their realm.

Once you accomplish this, the process is quite similar to creating a new Faith of an existing reformed Religion. Your vassals may still be reluctant to convert to your newly reformed Faith, but because reformed Faiths gain a bonus to conversion against unreformed Faiths, you will have a much easier time convincing them to go along with your reformation than a heresiarch within in an existing Faith would have with making a new heresy.

Tenet and Doctrine teaser

To finish this off, here are a few choice tenets and doctrines which you can pick when creating a new Faith in CK3. Many of these are also used by already existing Faiths, but some are only available to custom Faiths created by players. As you can see, there is a lot of variety in the kinds of custom Faiths you can create — ultimately every kind of playstyle should have some set of Tenets and Doctrines to support it!

That is all I have for you this week, but join us next time as my colleague @Heptopus talks about the diversity across the world in CK3 and the many different ways you can tailor the game experience to match your personal preferences!

EUIV: Emperor looks great and watching dev clashes I have one question. Will there be Hussitism? Or maybe even his branches like Taborites or Utraquists? Hussitism were created within the timeline of CKIII so it would make sense to have it :)

Vassal willingness to convert is based on Opinion, difference in Learning score, and their current Faith's Fervor.
Ah, difference in learning makes sense. So it does not matter how much your new religion deviates, since you already 'paid' for that with the higher piety cost?

Mods could make Theocracies 'playable' in the sense that you could launch the game and start playing as one, but you would soon run into a myriad of issues (such as Game Overing every time your ruler dies) due to the fact that you're breaking the game's internal ruleset and trying to make it do things it was never intended to do.
As long as there is a 'set_player_character' command, an 'on_death' action trigger, I have some experience with solving that issue. ;-) Hope that this is the main problem to fix.
Did you write event localisation for the Pope, like you did in CK2?

For Christian Syncretism, the 'Mutual Opinion Bonus' is specific to only Christians, though the opinion bonus for being Compassionate will apply to any faith that has Compassionate as a virtue, including Faiths like Hinduism and Jainism.
So there are probably more tenets like this for other religions as well? But I guess you did not make 99 of those, right?
 
I would be great when i reform my religion, it can have the something like college of cardinals,so the religion can have a Papal like succession.
also have Investiture

Also have religious Societies,so when i make someone take the vow. They will become a member of religious Societies.
In the CK2 when play pagen.they was very little Societies to enjoy.
 
Creating our own faith is going be awesome, I can't wait to start my own faith.
 
Will it be possible for you to change your faith but remain loyal to the previous religious head? For example another religious school under Sunni Islam, still loyal to the existing Caliph. Or to create Celtic Christianity that still recognizes the Pope in Rome and has fairly minor differences in penance practices. This could conceivably model the Great Schism where the leadership unity is specifically broken.

Is it possible to make a new 'parent faith'. Like if I wanted to play as a character who turns away from the abrahamic religions but sticks with monotheism and created something like the cult of Sol Invictus, would that be possible? Or would I first need to shop around for a good 'base' religion to build from?
 
3. You cannot form a Faith that has identical Tenets/Doctrines to an already existing one.

- Is this limited to the same Religion only, or is this prevented on a Family or even global level? For example, if all relevant Tenets and Doctrines for the Zoroastrian Faith are individually available when reforming the Tengri Faith, would the existence Zoroastrian Faith prevent that particular reformation?

- If it is limited on a higher level than Religion, can this limit be modded out? I'd imagine it would be annoying if someone else reforms another religion/creates another heresy before you using your preferred setup...

- Does a Faith that is dead still restrict creating a Faith with identical Doctrines and Tenets? If so, is that moddable?

in this same vein, im wondering if there might be a way to model the kind of.... really specific circumstances in iberia, where you get catholics influenced by muslims, but who are still wholly catholic.

im forgetting his name suddenly, who was the lad who tried to do muslim polygamy as a catholic. i thought it was alfonso vii but it wasnt him, it was a jimena im p sure. anyway im thinking of stuff like that, not quite full heresies but not really proper catholicism either
 
In the spirit of dumbing down the game, now that you purged terms like 'primogeniture' and 'ultimogeniture', why using the term "avunculate marriage'? Either you use these "complicated terms" or just the literal (and lengthy) definition of them. Consistence, that's the word for it...
No, the word is consistency.

>Carnal Exaltation increases fertility.

This is one of those thing that at first glance makes perfect sense, but if you actually think it through you realize it really doesn't.

What such tenet would realistically do, would be normalization of unorthodox, and thus non-procreative sex.
Therefore, lustful traits and such, should decrease fertility, not increase it.
 
For example, Islam is used to polyamory and will happily accept a new Faith espousing it.
Polyamory? I don't think that word means what you think it means.
Polyamory refers to open relations and "polyamorous religion" would be devoid of marriages, while Islam discourages polyamorous activities. You likely meant to use "polygyny".

Oooh? You can directly decide how your new religions followers are called?
That is gonna have some hilarious possibilites.
 
Wow, very much going to look forward to making splinter sects of various religions. Christian syncretism sounds rather neat! Really looking forward to seeing all the various tenets one can play with.

On that note, though, is it possible to limit divine marriage to just one's own household? Such often was limited to the ruling elite, rather than all castes and classes of the realm.

Excellent! Very much looking forward to this! As I posted elsewhere, the relative homogeneity in the dev diaries thus far was of a bit of concern to me. But to get an entire dev diary on it next week? Yes! Excited to hear what each region will offer! :)
 
Why not make sins gender based? Lustful men are OK but lustful women are not, or vice versa, or both, depending on gender equality setting?
Actually, this is a very neat idea. In fact I think that, more than religion, this will be extremely suitable and realistic for cultural features. In many cultures, some traits in one gender are not frowned upon but are considered very bad in the other gender. But since "cutural features" are most likely not going to be customizable by the player in-game, I think it may make sense to include such possibilities in religious doctrines. Especially as a modding possibility.

EDIT: Come to think of it, maybe if such a thing would be allowed by code, then modders can make custom cultures and culture groups with such gender-differentiated opinions about traits.

By the way, I'm almost 99.9% sure there'll be an achievement for forming an early Anglican/Protestant/Reformed heresy :D
 
This looking great.
Are there any limitations of what could be done or would we be able to establish multi gender polygamous marriages?
2 Happy males and one female to bear kids to carry on the line

Or 2 domiant females with one male to provide for offspring
Hello christianity 2.0 :)
