教宗選任法（英文：Papal succession）或樞機團（英文：College of Cardinals）是教廷的繼承法，僅限於 
亞伯拉罕之裔DLC。
天主教（或小兄弟會）教宗去世後，適任者被選作新教宗。
特點
- 九位樞機組成的樞機團進行內部選舉。
- 每有一位樞機去世，他將被教宗選擇的最適合的主教接任。
- 一位樞機被選作教宗後，他失去自己的教堂建築，樞機團中一個樞機位置空缺。
機制
樞機是宗教頭銜：
| 頭銜 | 數量 | 尊貴度（暫譯） | 好感修正 | 每月薪水 | 每月威望 | 要求 |
|---|---|---|---|---|---|---|
| 樞機 | 9 | 0.90 | +20 | +0.10 | +0.50 |
|
| 小兄弟會樞機 | 9 | 0.90 | +20 | +0.10 | +0.50 |
|
選舉有兩級：
- 樞機團空缺位置由教宗根據樞機任命分數授予主教，這取決於候選人和他領主的因素。
統治者可以投資競選經費，可以增加候選人選上的幾率。
- 樞機選擇下一任教宗，基於
教宗適任度分數，這取決於候選人的因素，統治者不能直接施加影響。來自特定統治者領地的樞機投票給教宗，教宗每獲得一張票將有一個+100的大量好感修正。
樞機任命和 共有的因素：
| 因素 | 分數 | 注釋 |
|---|---|---|
| 好感 | +3.5 × 教宗或樞機對候選人的好感 | |
| 世俗權力 | 頭銜力量總和 | 候選人持有的頭銜等級和數量：
|
| 文化 = 意大利 | +200 | 根據羅馬省份的文化。如果羅馬改變文化，將會改變；如果教宗遷都將不會改變 |
| 文化組 = 拉丁 | +50 | 不和意大利文化加成疊加。根據羅馬省份的文化。如果羅馬改變文化，將會改變；如果教宗遷都將不會改變 |
| 美德個性特質 | +（特質增加的教會好感值） | 增加正面教會好感的特質： +5， +5， +5， +15（只影響基督教教會好感的特質，例如忠貞，沒有算在其內） |
| 罪惡個性特質 | -（特質減少的教會好感值） | 增加負面教會好感的特質： -5， -5， -5，邪惡神職人員  -10， -15
|
| 學識 | +2/學識點 | |
| 虔誠 | +0.1/虔誠 | |
| 年齡 | +2 × 年齡 | |
| 聲名顯赫的家族 | +1 / 40 家族威望 | |
| 在羅馬的候選人 | +100 | 宮廷司祭，指揮軍隊，在領主宮廷 |
僅用於樞機任命的因素：
| 因素 | 分數 | 注釋 |
|---|---|---|
| 對領主好感 | （教宗對主教的領主的好感 + 教宗對主教的好感) / 2 × 3.5 | 無條件捨入 |
| 競選經費 | +1/投資金幣 |
策略
在某些方面，控制樞機團優於控制對立教宗：
- 你不會遭受宗教權威的不好影響。
- 你的教宗控制所有的天主教徒，不僅是你的國家，所以你可以對外絕罰和准許入侵。
- 你可以失去你的頭銜，仍然有一系列支持你的教宗。
- 你家族的教宗保護你所有的親戚，不管他們在哪裏。
選擇未來的樞機
使用角色查找器來確認合適的候選人，也許可以從那些意大利文化的人開始。除了特質，查看他們的虔誠和每月獲得的虔誠。
選擇親戚很好。你家族的教宗將：
教育（無御前會議）
如果你有耐心，在年幼時（6-10歲）根據他們早期的基礎數據和特質選擇未來的樞機。天才和敏銳最好，因為它們為學識屬性提供罕見的加成。
理想的監護人有高外交，高學識能力，以及4個及以上好的特質。七美德容易看到並且都有用：
| 特質 | 外交 | 學識 | 教會好感 | 樞機分數 | 每月虔誠 | 監護人* |
|---|---|---|---|---|---|---|

✗ | +1 | +10 | ✓ | +0.5 | ✗ |

* 通常將改善監護人做出的決定。
最終，潛在的未來樞機的理想教育者將是你的其他一位樞機或未來的樞機——或者你自己，最大限度地控制孩子的特質（除非你是專斷/殘暴）。
你的未來樞機是意大利文化將很有用。如果這個孩子不是意大利文化，參見通過教育轉變文化。考慮讓你自己轉變為意大利文化。You can always search for Italian characters by right-clicking any Italian character, selecting "go to character relations", and limiting the search to "my culture" [sic]. Alternatively, try to convert Rome to your culture, so it is your culture (rather than Italian) that gets the cardinal appointment score boost.
Just before the age of 16, switch the child to a 
if their guardian is not one.
成年
When he reaches the age of majority at 16, order him to take his vows. Becoming a 
will remove him from any succession lists and give him a monthly piety boost (until he loses the trait upon becoming a bishop).
If he is the son of a ruler and has high martial skill, try to get him a bishopric quickly, or he may try to join a holy order (costing you piety if you refuse).
If a Crusade is called, have him lead an army in the target kingdom to get the trait.
創建龐大的附屬神權政體
The secular power of the bishop is a major factor in cardinal selection. Most candidates are mere baron-level bishops; yours can have an edge. Furthermore, higher-rank clergy have more chances to gain monthly piety from church buildings. Their increased demesne limit lets them hold more churches, and they can have more vassals with churches, both baron-level and count-level. 主教的世俗權力是選擇紅衣主教的主要因素。 大多數候選人只是男爵級別的主教; 你可以有優勢。 此外，高級神職人員有更多的機會從教堂建築獲得每月的虔誠。 他們增加的私有限制讓他們擁有更多的教會，並且他們可以擁有更多擁有教會的封臣，無論是男爵級還是郡級。
You can create county-level bishoprics out of Holy Warred lands, or by revoking a county and granting it to a local bishop. You can then grant a duchy to the prince-bishop, making him a prince-archbishop. The technique is largely the same as for creating vassal republics. Theocracies cannot be granted kingdoms or create kingdoms, but it is possible to set up a theocratic kingdom by pressing a bishop's claim on a kingdom. 你可以在神聖戰爭的土地上創建縣級主教職位，或者撤銷一個縣並授予當地主教。 然後你可以授予王子主教一個公國，讓他成為王子大主教。 技術基本上與創建附屬國相同。 神權政治不能被授予王國或創建王國，但通過對一個王國施加主教的要求，建立一個神權政治王國是可能的。
Keep in mind that you cannot create more theocratic counties if more than 10% of your realm is controlled by theocracies. You must choose between having a large number of count-level direct vassals (preferably in safe, uncreated duchies) or a small number of higher-rank vassals.
If you have lots of money, construct piety-generating buildings in the temples belonging to your cardinals and their direct vassals. You can also build new temple holdings for them, even in counties controlled by feudal rulers—you are not obligated to transfer the temple holding to the local count.
神職敘任權
If you have Papal Investiture, nominate the member for the priesthood by asking the Pope himself. If he consents to the nomination then your designated family member will succeed to the next available bishopric within your realm.
Assassinate bishops in your realm to speed up investiture.
Holy warred counties can be converted to theocracies and given to your chosen person at the same time, bypassing the need for investiture (once).
協助樞機任命
To acquire the "In Rome" modifier, appoint your potential Cardinal as your Court Chaplain and send him to Rome on a mission to improve religious relations.
If all else fails, contribute money to his campaign fund until he is the best candidate. You should contribute at least some money for the "Supported Cardinal Election" opinion boost, which gives +30 for 83 years.
If you're feeling particularly devious, you could assassinate a Cardinal (or Pope) to make room for a new cardinal.
在羅馬培養教宗
As an alternative to creating cardinals in your own realm, it is possible to breed dynasty members in the Pope's court. The Pope is likely to make some of them bishops, and they will have an edge in cardinal/pope elections thanks to being in Rome and the correct culture.
