CK2 Dev Diary #106 - New Succession Laws Extravaganza

Greetings, everyone.

Well then, this is going to be a long one...

The old elective succession system has been succeeded


So your cousin the Duke of Burgundy always seem to nominate the Steve ‘the drunkard’ as the next Emperor of the realm rather than your favorite quick and attractive son. This has been a common theme for a bunch of our playthroughs while having the elective succession laws active for our main titles. One of the biggest problems about this is that the other electors reasonings for their nomination decisions has been hidden away in an opaque box so you never know which electors can be influenced to see things more in your way.


This was one of the first problems we wanted to address when we decided to rework the elective succession system. So instead of just giving you a list of names in the tooltips for whom casted votes on a given candidate we made a specific interface to enable us to give you a more detailed view into the minds of the powerful electors of the realm.

After it was possible to get a better look at why the electors made their decisions we wanted to make it easier to further edit the underlying factors which governs the AI. Therefor we decided to replicate the old logic from hardcoded conditions to instead be based on a scripted system which decides various rules of how the elective succession works.

This not only enables modding of the elective succession law, we now also allow you to create any number of your own elective rules to fill the world with different electorates that play by their own criterias. Maybe you always wanted to create your own technocratic republic that is governed only by the most learned people of the realm. The party realm might only allow drunkards and hedonists to have a say in whom should be this years party host.

For the people that are more interested in exactly how this is modifiable there’s a brief rundown of the syntax used to define the elective rules here:

Code:
### Condensed syntax layout:

#<elective_law_type> = {

#    candidate_vote_score = {

#        <Weight Modifiers>

#    }

#    elector_selection = {

#        max_amount = <int>

#        <Weight Modifiers> - if max_amount is set it will pick the X amount of top scorers.

#                Negative scores are considered invalid electors - Ruler is always an elector

#    }

#    elector_vote_strength = {

#        <Weight Modifiers>

#    }

#    elector_stances = { - Intended for the elder council positions

#        <stance_name> = {

#            icon = <int>

#            <Weight Modifiers>

#        }

#    }

#    candidate_trigger = {

#        <trigger>

#    }

#}


# <Weight Modifiers> - denotes a field of an arbitrary amount of triggered value modifiers eg.

#    additive_modifier = {

#        value = -4

#        is_tribal = yes

#    }

#

# <trigger> - denotes a field of conditions that needs to be evaluate true for the trigger to be fulfilled

#

# The elector will vote for the candidate with the highest score given by candidate_vote_score

# The electors are selected from the pool of characters which get a non-negative elector_selection score until we reach the max_amount

# elector_vote_strength will determine how much weight the vote of a single elector carries

# The elector will use the elector_stance with the highest score if any are scripted

# The stances are thought to be some kind of common thought process or allegiance for a subgroup of the electors - This system is used to create the different states for how the Elders will behave in the Eldership succession law explained in detail below

In addition to these underlying code changes of the elective succession forms we also added another usage of the Conclave favors so that you now can force electors to vote in compliance with your vote for the succession of a title.

Revamped Elective Laws


The unhardcoding of Elective successions allowed us to completely rewrite the AI behavior for the existing Elective laws accessible through the base game (Feudal Elective, Elective Gavelkind, Tanistry). The various conditions to be eligible as a successor or elector under these laws have remained unchanged (although now they have been translated into moddable script), while the AI electoral behavior has been rewritten into a long list of nuanced modifiers. You can now expect Electors to take into account how much they like a candidate, how legitimate they think his claim his to the title, and how much they trust the ruler that is voting for said candidate. Age, titles, character traits, culture, religion, dynastic ties and much more are now all taken into consideration by the AI and visible to the player when using the new Electors’ Tab. The sum of all these modifiers will result in a voting score, and the potential candidate who has the highest voting score will be the one selected by the Elector in question (and since each Elector has a different personality/status/etc. different kinds of Electors will prefer different kinds of candidates).

Succession Laws1.jpg



The Electors Tab shows to the player the complete list of Electors casting their vote, who they are voting for, the reasons why they are voting for said characters as well as a comparison with the candidate score of the ruler’s preferred candidate and the reasons why they are not voting for him.

Eldership

Somewhat similar to Tanistry, Eldership prevents your title from ever falling outside a ruler’s family, restricting the choice of potential candidates to members of the ruler’s dynasty. Under Eldership, only the six oldest and most learned characters in the realm will be allowed to pick the ruler’s successor. Each Elder can hold one of three possible stances at any given time, depending on how he feels about the ruler: Displeased, Pleased, or Ecstatic.

Making sure that your Elders have a high opinion of you, giving them their preferred Council positions (Chancellor, Steward, Chaplain), or fulfilling the occasional request from them, will push them further to become Ecstatic.

20180824080508_1.jpg


An Ecstatic Elder will almost always vote for the ruler’s chosen candidate, almost never make demands, and even give the occasional piece of advice to make you a better person.

20180824080639_1.jpg


Pleased Elders will try to vote for what they consider to be good and capable candidates amongst the members of your dynasty, favoring older characters with high stewardship. They might occasionally make some demands, such as asking a ruler to give some land to a family member that they really like, but they will, for the most part, be reasonable people to deal with.

Displeased Elders on the other hand, will be much harder to deal with. Not only will they purposefully select bad candidates, they will occasionally grant claims on your title to people that they like, openly questioning their liege’s right to rule.

20180824080819_1.jpg


Holy Fury will allow the Baltic and African realms to start with Eldership as default succession law, rather than Elective Gavelkind. Additionally, other pagans can unlock this succession by picking the right Doctrine when they Reform their faith.

Princely Elective
This new variation on elective has been scripted to replace Feudal Elective for the Holy Roman Empire. This succession limits the electors to a maximum of seven (plus the ruling Emperor) and makes it so the historical titles held by the Prince-Electors are prioritized when determining the valid electors in the Empire, these titles being the Bishoprics of Mainz, Koln and Trier, and the Duchies of Bohemia, Franconia, Saxony, and Brandenburg. If an elector title does not exist or his held by the Emperor, another valid Duke will replace it (prioritizing dejure vassals of the same religion as the ruling Emperor).

20180824081547_1.jpg


Electors under Princely Elective are overall much less likely to pick candidates that are either impious or of a different religion, and Theocratic Catholic Electors have twice as much voter strength than secular Electors whenever the Empire is under Papal Investiture.

While rulers of the Holy Roman Empire can still change the realm’s succession law as usual, the faction for Elective has been made much more easily accessible and palatable for vassals of the HRE and requirements to switch away from this succession have been made more restrictive (the ruler must have Max Centralization and either Absolute Crown Authority or Abolished Council Power).

Imperial Elective
And finally, a completely new succession law has been scripted for the Byzantine (and Roman) Empire, to better represent the peculiar politics of this realm. This succession has been tied to the two titles and is now also the *only* succession law that they have available. There are several features that are unique to this succession law, so I will explain it in sections:

20180824081910_1.jpg


Successors: Potential candidates under Imperial Elective include the Emperor’s children and close family members (spouse included), any claimants to the title, the current Marshal, and any Commander under the Emperor, with mutilated characters being excluded. This is to represent the influence of the military over Byzantium and allow more historical instances of influential commanders becoming Emperors.

Imperial Court: The Emperor, all of his Councilors, and all of his Commanders are valid electors. As Byzantium was a centralized power, the Emperor will need to curry the favor of the most powerful members of his court to ensure that his dynasty continues to maintain the throne, rather than his vassals, like a Feudal ruler would.

Scaled Voting Power: And this is where things get really interesting. Imperial Elective uses to its full extent the new voter_power function of scripted elective, making sure that every elector has a different amount of influence, entirely dependent on his status in the court and his attributes. The Emperor’s vote starts out with a strength of 200 voting power, which can be further boosted by good diplomacy and martial scores, making it so that a powerful and influential Emperor will be able to push the candidate that he wants on the throne even if most of the Court is against it. Conversely, if the Emperor is not Born in the Purple, deformed or crippled, or if he has made a reputation of appointing sycophants in his court (more on that below), he will see his voting power plummet. The other Electors have their own variable voting power, tied to prestige, rank and attributes (a Steward with high stewardship is more influential than an incompetent one). As such, appointing competent people to be your councilors and commanders will not only mean that your favorite son will have to compete with more competent and palatable candidates, but also that the electors will have a greater influence over the succession. Finally, minor titles can also affect a character’s voting power, so you might want to think a bit more before giving out your Caesar and Sebastokrator spots.

20180824082114_1.jpg


Heroes and Sycophants: Is Belisarius too popular a Commander for your sons to compete with him? Well, you can always discharge him: take away his status as Commander and he will no longer be a potential candidate or an elector, problem solved. Except... when under Imperial Elective, removing a competent Commander or Councilor from his position reduces the Emperor’s voting power of an amount proportional to the competence of the character you are removing. The more competent people the Emperor pushes out of his court, the less his vote will be worth overall. Same applies whenever an Emperor appoints a commander with poor martial score while there are clearly superior choices available: the court will notice that you are appointing mediocre sycophants because you fear competition and you will see your voting power go down. Additionally, Imperial Elective prevents Emperors from appointing landless commanders for as long as potential vassals are available to take the spot. If you wish that high-martial courtier to lead your armies, you will need to give him a proper title first.

Prestige and Ageism: This is not Feudal Elective, the Empire does not care as much about family ties and character traits, it cares about placing a competent and prestigious leader upon the throne. For the Byzantine Empire, this translates to the electors tending to favor skilled high-Intrigue characters, whereas the Roman Empire electors are keener on good orators (high Diplomacy). In both Empires, the electors will always favor people that are competent at their job, that have high prestige and titles (both minor and landed). One of the most visible consequences of this is that hardly anyone under Imperial Elective will ever consider a child to be a valid successor to the throne. If you wish your son to take your place, you will have to groom him first, wait for him to become adult, then push his bid to your Empire, possibly giving him a few honorary and landed titles along the way. While he’s still a toddler, it might be more sensible for you to appoint your younger brother, or your old uncle as preferred heir, just in case something happens before the little Prince comes of age...

20180824082155_1.jpg


Strong Claim Duel
Somewhat related to all these new succession forms, we have also added a new type of duel designed to let players keep their realms together after an Elective Gavelkind succession. This Strong Claim Duel is available regardless of whether you have the War Focus active, or if you are a member of a Warrior Lodge (which is otherwise required for regular dueling). As a tribal character, with a Strong Claim on a title currently held by a tribal ruler, it will be possible to issue a challenge to the current title holder, with the requirement of your target ruler either being independent, or both of you being vassals under the same liege. Bear in mind that the stakes in these duels are high, and losing does not only mean you give up your claims - unless you have a particularly kind opponent, who loves you dearly, death is the common way out of this dispute. Winning, on the other hand, means that you take the title in question and any vassals that come with it, along with any other of their titles on which you have a Strong Claim.

If the target of your Claim Duel happens to be an AI character of your own Dynasty, losing will present players with a choice: accept your fate, or click the option to take over as the character who won the duel, and continue to play the game as the kinsman (or woman) who bested you.

Succession Laws3.jpg
 
- Is it possible to change the number of electors in Princely Elective during the game (with events/etc.)?
Not as a direct command, no. It might be possible to simulate a change in their number with some workaround, playing with the elector selection or creating variants of the election itself, but by default, the max number of electors (if defined) is set in the succession law itself and remains static when in game.
- Is it possible for the number of electors under Princely Elective to be different for different realms?
No, but you could set different variants of the same succession law, and mod it so, depending on the realm, when the law is implemented, it follows one or the other depending on whatever triggers you wish to set.
- Is there a way to scope to the top X candidates (or all candidates with at least one vote) and their supporters post-election (or on_death for the title holder) if we want to do something like e.g. give them the option to instantly start a civil war for the throne?
Hm, not sure about this, @Divine might know.
- Is it possible to scale voting power based on manpower/personal levies/retinues/etc. or on demesne size?
It should be possible to use most existing conditions that can be set as a trigger for a character or title, yes.
- Is it possible to block specific electors from voting in an election (e.g. an imprisoned traitor (or "traitor"))?
You could script it so that an Elector with the "traitor" modifier or who is imprisoned by the liege is no longer a valid elector, which would prevent him from voting until the condition preventing him from being a valid elector is removed.
- Would it be possible to do "appointment voting" (for viceroyalties) where the liege and his councillors (and perhaps the holder, since he might try to buy votes) are the electors and the title instantly goes to the chosen successor?
That should be possible, yes.
- Given the party realm example, is it possible to script some elections to take place every X years instead of on_death?
Maybe there is a workaround to make something like this work, but it would need to be handled by events, there is no specific command for it that I know of.
- Since it is somewhat similar to Princely Elective, is Papal succession's voting logic moddable?
No, Papal Succession itself is not counted as an elective type (same for the Merchant Republic succession) in this context. I suppose it could be possible to mod different successions with this system and tie them to theocracies and Cardinal titles, but I don't know how would that mix with the Papal interface, there might be oddities.

- Have there been any anti-bordergore changes to what happens to non-de jure titles on election (excluding the changes made with the exclave rules)? For example, if Harald wins in 1066 but England and Norway split on succession, Cornwall currrently stays with Norway (presumably because that's the primary) despite the fact that it is much closer to England and would look a lot better there.
I don't think so, no.
- How severe is the priority for historical elector titles? For example, if I am an elector as Lotharingia and my vassal (or some random person) creates Trier, will I instantly lose my elector status because that's a historical elector title?

- Is the AI smart enough to not grant historical elector titles to vassals if this would give up the elector position?
They are prioritized quite a bit, so you might be losing your Elector status in that circumstance, yes.
Not particularly.
1.Are all these variabel by gender preferance laws?
Yes, all new succession laws combine with gender laws as usual, and the AI's behavior will take them in consideration amongst other things when picking their preferred candidate.
2. How hard is it to place a prefered candidate on the throne of byzantium as an outsider? Is marrying my ruler to a greek princess and raising our son as intricatre webweaver enough to give him a decent shot in adulthood if the ruling dynasty is weak(end by me)?
It might be feasible, yes, it depends on the state of the ruling dynasty, on potential competitors to the throne, how much the Emperor's Councilors like your preferred heir, etc.
3. Are you planing on dehardcoding merchant republics in the future?
No plan as far as I know.
 
Once again I am speechless.

There will quite literally be too many good options to play as for my first game with the new DLC !
 
I saw a couple of folks ask this question, and I don't think this was answered already.

If I imprison an elective voter for a valid reason (caught plotting to kill my kid, rebels against me and loses, etc.) will that reduce or eliminate the voting malus other electors would have of me when it comes to selecting the heir? Similarly, if the elector happens to die in my oubliette (without any foul play on my part), will the other electors hate me for it the same as it I executed a kill plot against that elector?

My assumption is that I wouldn't get dinged for an "understandable" response to a treasonous action by a vassal. If not, then that means that your elector vassals might be emboldened to conduct high intrigue actions against you, knowing that any retribution against them would have major repercussions for your rule.
 
Amazing, and very unexpected. Guess I'll be doing my first byzantine playthrough next!

Two questions:
Can vassals use favours to influence other electors? Please make it so.

Can the elders be limited to vassals and your court rather the whole realm? Otherwise bigger realms will just end up with a bunch of no-face electors of no importance.
 
Would it be possible to mod in a "census elective" succession where only the most wealthy courtiers are electors ?

(For example, the X most wealthy courtiers in the realm, or only the courtiers that have more than X gold in their personal treasury)
 
Great news!

I have a question: will the HRE created in the Charlemagne start use the Princely elective succession law? It kinda feels wrong in this case, especially considering that the de jure titles that are prioritized as electors might not be under control of the HRE in that case.
 
Not a question about the succession itself, but now that the Byzantines characters can hold cities, will the holding of Constantinople be a city, rather than a castle? Obviously, with the Theodosian Land Walls. Pretty please?

If you are not gaining tyranny and the other electors' opinion of you is not going down, then they are not going to care.
If you are referring to killing/imprisoning Elders, if you have a legitimate reason, the other Elders will not get upset with you.

Yes, that seems feasible.

The official HRE yes, the pseudo-HRE no.
Do titular titles count for the purposes of being Commanders in the Byzantine Empire? e.g. can the holder of the Varangian Guard be a Commander?
No, a Commander is defined as a character that you have given the title_commander in order to make him lead your armies. You can make the Varangian Guard leader your Commander, sure.
 
I would like to know how will be the impact of the Enatic clans, would fit somehow to the dev dairy will it just be a click while a reform the religion or maybe what will be the consequences of it, right now many events for rulers and descisions are linked to male rulers

This is what I meant, thanks!

On a related note, is there any change to whether Marshals need to be landed in the Byzantine Empire? I'm hoping not to allow for Eunuchs being Marshals (aka the most senior general) and leading troops, along with relatives of Strategoi who didn't themselves hold a command, as happened under various rulers!
 
Not a question about the succession itself, but now that the Byzantines characters can hold cities, will the holding of Constantinople be a city, rather than a castle? Obviously, with the Theodosian Land Walls. Pretty please?
Well, not "the Byzantine characters", just the Basileus.
Other characters in the ERE are still feudal. So that might be a problem if Constantinople happens to no be held by the Basileus anymore.
 
Would you consider adding Eldership succession as a bloodline feature for a legendary Romuva bloodline (custom or pre-existing)?

I would love to play around with the new succession without being bound to the specific religion, like how Niall's bloodline enables tanistry for non-celtic rulers.
 
- Have there been any anti-bordergore changes to what happens to non-de jure titles on election (excluding the changes made with the exclave rules)? For example, if Harald wins in 1066 but England and Norway split on succession, Cornwall currrently stays with Norway (presumably because that's the primary) despite the fact that it is much closer to England and would look a lot better there.
I don't think so, no.
Shouldn't the new 'Exclave Independence' mechanic do this to some extent? It wouldn't make Cornwall part of England but would certainly reduce the bordergore after-effects.
 
If you are the ruler and using Elder succession, and you are the oldest person in your nation, are you an elder? Or is the ruler ineligible for elder status?

As a side question, how does immortality affect elder succession? Will an immortal vassal always have a say in my successions? Can I be an immortal vassal and always have a say in who my next liege will be? Or are immortals disqualified from being elders?
 
Can you preemptively duel other strong claimants before the title holder dies?

What about dueling on part of other's claims (wife or son)?

Or using champions to duel for one?

Can incapacitated or sickly characters be challenged to duel?

What about women being challenged to duel?

There are currently no ways to duel on behalf of others, so that's a no.

Incapacitated characters should not end up in duels. Certain levels of injury/sickness might still be allowed, but they come with a scaling opinion penalty (from others in your realm), depending on severity of the health issues of your target.

Worth mentioning might be that we have simplified the game rules surrounding dueling to be "Default" and "Unrestricted" (where before there was also a "Restricted", kind of in-between setting), as we quickly realized that the system is more fun if it lets you be penalized for your behavior, rather than outright blocked from it. Same goes for dueling priests, or female characters, when not appropriate within your religion or culture (female fighters of the Warrior Lodges are fair game, for instance). Of course, your targets can still refuse your challenge. But to break it down, the default setting applies penalties, whereas "Unrestricted" is less concerned with what's an "appropriate" dueling target.

(Edit: Forgot your first question): yes, usually. As long as they are in general valid targets for you to duel, you should be able to pick them off beforehand (not without risk, but sure). :)
 
I would like to know how will be the impact of the Enatic clans, would fit somehow to the dev dairy will it just be a click while a reform the religion or maybe what will be the consequences of it, right now many events for rulers and descisions are linked to male rulers
There has been some background maintenance to upgrade old basic events to work properly with Enatic, but that is about it, I'm not sure that would warrant an entire Dev Diary. It was mostly about updating already existing events.

Looks really cool, although one thing I'm curious about: Can women take part in Imperial succession?
If for whatever reason a woman qualifies as an elector (wife, special Jean of Arc commander, etc.), she can vote, yes. In order for women to be viable candidates though the realm must have a gender law that allows it (that is, not full agnatic).

On a related note, is there any change to whether Marshals need to be landed in the Byzantine Empire? I'm hoping not to allow for Eunuchs being Marshals (aka the most senior general) and leading troops, along with relatives of Strategoi who didn't themselves hold a command, as happened under various rulers!
There is no change regarding Marshal, but a Eunuch is very unlikely to be supported by anybody and is likely going to have a very low voting power due to his mutilation.

Well, not "the Byzantine characters", just the Basileus.
Other characters in the ERE are still feudal. So that might be a problem if Constantinople happens to no be held by the Basileus anymore.
Yes, no change in Constantinople's baronies' type.
Can I have this answered please?
The Kingdom does not take precendence.
I had considered the possibility of having special circumstances where the main electoral titles can change (such as the one you named, as well as some of the other new special titles creatable by decision within the HRE, such as the Grand Duchy of Austria or the Swiss Confederacy), but would have taken a lot more time as I didn't want the electoral titles to be too malleable in a way that was for the most part outside the player's control.

Shouldn't the new 'Exclave Independence' mechanic do this to some extent? It wouldn't make Cornwall part of England but would certainly reduce the bordergore after-effects.
Yes, it should. I said no since the first post specifically said "excluding the Exclave rule".
