Changes to existing religion features:
- Warmongering, Unyielding, Peaceful, Proselytizing, and Dogmatic no longer have any effect on whether or not characters will try to convert provinces they own. All reformed religions are set to always convert owned provinces by default. However, Cosmopolitan still makes the AI not convert provinces.
- Warmongering, Unyielding, Proselytizing, Dogmatic, and Cosmopolitan no longer enable raiding and great holy wars.
- Great holy wars are enabled by Temporal and Hierocratic leadership.
- Autocephalous leadership gives +20 temple vassal opinion and allows you to force a vassal religious head to abdicate.
- Autonomous leadership no longer provides an attribute bonus. This is unfortunate but was necessary in order to facilitate many of the doctrines. Instead it now allows you to pick a extra doctrine.
- Proselytizing and Dogmatic no longer cause you to lose piety if attacking same religion
- Cosmopolitan no longer has a MA penalty. Instead it now prohibits great holy wars.
- If you don't also have Syncretic, Cosmopolitan enables decision to gain sympathy for another religious group.
- If you do also have Syncretic, Cosmopolitan gives infidel vassals a decision to gain sympathy towards the liege's religious group.
- Warmongering now gives a 20% levy size bonus (instead of enabling great holy wars).
- Warmongering (and offensive pagan religions) no longer allows you to raise vassal levies without upsetting your vassals.
- Unyielding doesn't give any levy or garrison size bonus.
- Unyielding (and defensive religions) now gives +100% morale and +50% garrison size in home terrain, but no bonuses to defense, levy size, or garrison size in general.
- Monastic no longer provides a learning bonus. In an update it will provide access to monastic orders, but I wasn't able to implement that yet.
- Monastic enables Monastic Feudal government for Tibetan rulers.
- Religious Tax changes AI behaviour so that rulers do not convert provinces of religions from other religion groups.
- Ancestor Veneration no longer requires a religious head to work. Blessed ancestors are determined automatically. You can now combine it with any type of leadership.
- Animistic rites of passage bug fixed. Bonuses now last for 30, 20, or 10 years (AI always takes the 20 year bonus). AI will only use the Sign of Power (reduced revolt risk, increased income) if it's count tier or higher.
- Animism doesn't give a land morale bonus.
- Unrelenting now gives +20% land morale instead of the 10% attack bonus and ignoring defensive attrition (there is a new doctrine for that).
- Agnatic & Enatic clans now force strict Agnatic/Enatic succession. Agnatic-Cognatic and Enatic-Cognatic are no longer allowed.
- Sea-bound allows you to raid (if you don't have Peaceful).
- Pyramid Creation now grants -10% great works construction cost & time

New leadership:
- God-king (leadership): temporal religious leader that is considered to be the high god of the religion and has special feudal/tribal government that allows holding temples in addition to castles/tribes and allows free revocation of all vassal titles; requires Divine Marriage doctrine; doesn't automatically enable great holy wars; replaces Dogmatic + Divine Marriage + Temporal synergy

New doctrines:
- Unity: +10 same religion opinion, lose piety if attacking same religion
- Kinship: +10 dynasty opinion
- Consorts: allows taking consorts
- Free Love: +10% Fertility and followers can become Lustful by decision
- Joy of Life: enables a decision that removes Stressed/Depressed or gives an event modifier bonus to diplomacy/fertility/dynasty opinion
- Temple Builders: +10 temple vassal opinion and -25% temple holding construction cost (stacks with monastic order bonus)
- Untamed: raiding is allowed, ignore defensive attrition
- Horse Cult: +20% attack and defense bonus for Light Cavalry, Horse Archers, Camel Cavalry
- Warrior Elite: +20% attack and defense bonus for Heavy Infantry, Heavy Cavalry, War Elephants; incompatible with Populism
- Populism: +20% attack and defense bonus for Light Infantry, Archers, Pikemen; incompatible with Warrior Elite, and God-king
- Anti-feudal: enables special new government type called Religious Community that replaces feudal; allows holding castles, temples, and cities without penalty and +20 vassal limit, but can't usurp or create kingdoms and empires, can't imprison without reason, and forced to use a special new elective succession that focuses on Piety and Learning of the candidates; requires Populism and Autonomous leadership
- Holy Warriors: enables two retinues that can be hired with Piety; type of retinues is based on the terrain of your capital; synergy with Enatic Clans also allows hiring Amazon retinues (Archers or Horse Archers); requires Legacy of Rome DLC

Holy Warriors retinues by capital province terrain:
- Plains: Light Cavalry and Heavy Cavalry
- Farmlands: Heavy Infantry and Heavy Cavalry
- Forest: Archers and Pikemen
- Hills: Pikemen and Heavy Infantry
- Mountains: Light Infantry and Heavy Infantry
- Steppe: Light Cavalry and Horse Archers
- Jungle/Marsh/Arctic: Light Infantry and Archers
- Desert: Light Infantry and Camel Cavalry


Ureformed pagan religions are designed as a combination of five doctrines. The one marked with [square brackets] is also inherent in the reformed version and you get it for free when you reform.
- Norse: [Sea-Bound], Warmongering, Daring, Unrelenting, Consorts
- Tengri: [Horse Cult], Warmongering, Ancestor Veneration, Animistic, Consorts
- Romuva: [Ancestor Veneration], Unyielding, Animistic, Sea-Bound, Consorts
- Soumensko: [Animistic], Unyielding, Ancestor Veneration, Kinship, Consorts
- Slavic: [Joy of Life], Unyielding, Ancestor Veneration, Animistic, Consorts
- African: [Animistic], Syncretic, Ancestor Veneration, Equality*, Consorts
- Zun: [Syncretic], Stability, Unrelenting, Warrior Elite, Consorts
- Bon: [Monastic], Unyielding, Equality*, Stability, Consorts
- Hellenic: [Haruspicy], Syncretic, Astrology, Meritocracy, Monastic*
- Aztec: [Bloodthirsty Gods], Warmongering, Unity, Warrior Elite, Consorts

Notes:
- When AI characters reform a religion they generally take 1 or 2 doctrines that match the unreformed version.
- Equality* means Absolute Cognatic is allowed, but unlike with the actual doctrine it is not enforced. Agnatic is prohibitet, but rulers can still be Agnatic-Cognatic. It also does not enable having female councilors.
- Unreformed pagans with built in Ancestor Veneration have half the normal chance to get venerated ancestors. Reformed Romuva has the normal chance.
- Bon & reformed Bon can join the Buddhist monastic order as a temporary measure until proper pagan monastic orders are implemented.
- Hellenic is considered Monastic* because it grants access to a pseudo-monastic order (the stoics) and because priests can't inherit.
- Some doctrines are unavailable to certain reformed religions because they conflict with the inherent doctrine. Zun can't be Dogmatic, Tengri can't have Warrior Elite or Populism (and by extension Anti-Feudal), and Aztec can't be Peaceful.

In addition to the above the various pagan religions are also considered to be either civilized or uncivilized:
- Civilized pagan religions have normal succession laws, normal short reign penalty, do not have defensive attrition, and do not enable raiding. They are Hellenic, Zun, Bon, and Aztec.
- Uncivilized pagan religions have double short reign penalty and do not have access to Primogeniture, Ultimogeniture, or Elective Monarchy successions, but they all get Eldership succession if they are tribal, they benefit from defensive attrition, and they can raid. They are Norse, Tengri, Romuva, Soumensko, Slavic, and African.

All unreformed pagans also still have their Pagan Subjugation CB that they can use once per life to subjugate another pagan ruler if they're either tribal or have Elective Gavelkind succession. In addition they can now subjugate a ruler of lower rank regardless of religion, but that uses the same once per life limit as Pagan Subjugation. Essentially this means unreformed pagans can perform one subjugation per life, using either Pagan Subjugation or the new generic Subjugation. Failed subjugations do not count against the limit.

Changes to non-pagan religions:
- Catholic/Messalian/Sunni/Shia/Jain/Mazdan group: unchanged
- Fraticelli: added Give Large Donation decision (lose 500 gold, gain 200 Piety)
- Lollard: added Peaceful, Populism, Stability, +2 Stewardship & Learning, and an ambition to become Honest, Just, and Diligent
- Waldensian: added Peaceful, Populism, Anti-Feudal, Give Large Donation decision
- Cathar/Bogomilist: added Peaceful, Populism, Anti-feudal
- Orthodox/Monothelite: added +20 temple vassal opinion, a decision to replace vassal religious head, intermarriage with Slavic and Germanic pagan
- Iconoclast: added +20 temple vassal opinion, a decision to replace vassal religious head, +10 Muslim opinion & -10 opinion from other Christians, intermarriage with Sunni
- Miaphysite/Monophysite/Paulician: added Unyielding, intermarriage with Muslims
- Jewish group: added Unyielding, can't demand conversion
- Nestorian: added +2 Diplomacy & Learning
- Yazidi: no jihads, can't demand conversion, hard to convert, no intermarriage with other religions
- Zikri: no jihads, Peaceful
- Druze: no jihads, Unyielding, can't demand conversion
- Hurufi: no jihads, +2 Diplomacy & Learning
- Kharijite: -4 Diplomacy, +2 Martial & Intrigue, allows Agnatic-Cognatic succession
- Hindu: added Warrior Elite
- Buddhist: +2 Diplomacy & Learning instead of +4 Learning
- Taoist: added Melliorism decision (also benefits from Stability + Meritocracy synergy), +2 Learning (in addition to existing +2 Stewardship), subjugation CB (vs any lower tier ruler; once per life; can't be used by Western Protectorate)
- Zoroastrian: added +5 Persian opinion and an ambition to become Honest, Just, and Diligent

Other changes:
- Added river movement to all religions.
- If your religion allows heir designation and you have Imperial Elective succession you get +300 voting strength.
- Eldership now uses twice as many elders (12 instead of 6) and the elders need 80 opinion to become ecstatic (instead of 60). That should make it less trivial to control the vote.
- Max tribal organization or being feudal enables Gavelkind and Seniority for all non-Muslims (this mainly makes them available to unreformed pagans, but it also makes Seniority more useful for non-pagans because it doesn't directly compete with Primogeniture).
- Tibetan cultures are eligible for Monastic Feudal government with any monastic religion (Bon, reformed Bon, and Buddhist as well as Hindu, Jain, and all Christian religions)
- Religions that allow Absolute Cognatic succession no longer allow Agnatic succession, though Agnatic-Cognatic is still permited.
- Unreformed pagans are allowed to use the decisions to Adopt Feudalism or Found Merchant Republic.
- Germanic pagan demon child events now give Possessed, Arbitrary, Cruel, and Wroth when the demon child reaches adulthood.
- The rare reincarnation flavor event is now available to Hindu, Buddhist, Jain, (reformed) Bon, (reformed) African, Mazdaki, Manichean, Khurmazta, Cathar, Yazidi, and Druze characters.
- You can legalize bastards even if you don't have 20 Piety, but doing so will still cost you 20 Piety (so you can go negative).
- Changed the tattoos for non-African animists to make them a less jarring.
