Stellaris Dev Diary #247 - New Ways to Rule

Hello everyone!

In the Overlord Announcement last week we mentioned that vassalization mechanics will be undergoing some significant changes in the 3.4 “Cepheus” update. (Click here to wishlist!)

Previously in Stellaris, subjugation was rarely a more compelling option than simple conquest, and being subjugated often essentially meant a permanent decline of your empire and a “Game Over” screen in your near future. Subjects did not offer sufficient benefits nor had the freedoms necessary to be enjoyable to play.

The Scion origin from Federations was somewhat of an exception with most of the restrictions on both subjects and overlord being waived for them, but we felt that while the system was good, it could be even better. It would also be nice for the Scion to work within the rules rather than being so “special-cased”.

Some people noted that as part of the unity changes in Libra, a bit more of an argument for spinning off sectors into vassals could be made, but with the current numbers it’s generally more valuable to control those systems directly.

For today’s dev diary, I’ll start by delving deeper into the new rights and responsibilities that can appear in agreements, and some ways this makes keeping subjects more valuable.

As with all previews, numbers, text, and so on are not quite final and are still subject to change.

Negotiating Terms​


Both the overlord and subject will be able to propose alterations of the exact terms of their vassalization contract if it’s a contract with another “regular empire”. The Khan, Awakened Empires, and the like do not haggle about the terms of their minions, but are much clearer about those exact terms.

Subject contracts start with a “preset”. These are the basic subjugation types that you know from before, plus a few new ones - Vassal, Subsidiary, Tributary, Protectorate, Bulwark, and so on. Presets have a list of default terms, and can have additional unique effects tied to them, like how Protectorates gain a massive bonus to research until they catch up to their overlord.

The default terms of contract presets may have changed a bit from the old system to better fit the new. We’ve done our best to ensure that anything you can do right now with your vassals remains possible. The core Negotiation system is part of the free Cepheus update, though many of the brand new terms are part of the Overlord expansion.

Negotiable terms include things such as:
  • Can the subject be integrated?
    • As a major change from current gameplay, there are no vassalization contract presets that have integration enabled by default. It must be explicitly turned on in contract negotiations.
  • Does the subject have independent diplomacy?
    • Subjects can be given complete diplomatic freedom, none, or they can have most freedoms except are forced to vote with their overlord in the Galactic Community or Federations.
  • Can the subject expand freely?
    • Once exclusively the province of Feudal Society, now you can grant your subject the ability to freely expand. You can also bar them from expansion, or impose an Influence tithe, making them spend extra Influence (which goes to the Overlord) for the right to expand into empty systems.
    • Most presets will start with controlled expansion with the influence tithe as the default term.
  • Various subsidies from the overlord or tribute from the subject.
    • These are broken into Basic, Advanced, or Strategic resource groups, and Research.
    • The values are percentages of the production of the subject - in the proposal below, our vassal is offering 15% of their basic resource production as tribute, but is receiving a research subsidy equal to 15% of the subject’s research from the overlord.
  • Are the overlord and subject drawn into one another’s wars, and if so, which ones?
    • None, Offensive, Defensive, or Both can be selected in both directions.
    • Yes, this means that wars can be declared on subjects.
  • Can the overlord build holdings on the subject’s worlds, and if so, how many?
    • The Vassal preset has a holding limit of 1, allowing you to use some holdings without Overlord. (Though you can lower it to 0 if you need to squeeze out an extra bit of loyalty.)
    • This value is an empire-wide limit - with a holding limit of 3, you can build 3 holdings across a particular subject’s worlds, not on each of their planets.
  • Does the overlord share sensor information with their subject?

Subjugation Proposal UI

Some subject types have fixed, minimum, or maximum terms - Tributaries, Subsidiaries, and Prospectoria, for example, must always provide their overlord at least 30% of their basic resources (energy, minerals, and food) in tribute.

Part of the Tributary agreement UI

Tributaries have many locked terms.

Others can be restricted by civics or for other reasons - for example, overlords with the Feudal Society civic cannot select the Expansion Prohibited term, must join in their subject wars to some degree, and must allow their subjects some degree of diplomatic freedom.

Feudal Society civic

Different terms affect a subject’s Loyalty, and have an immediate impact as well as over time. For example, the Independent Diplomacy term grants 5 Loyalty and another +0.5 Loyalty per month. This may prove important later.

If you’re asking your subject to do something they are ideologically opposed to, those terms may cost extra loyalty, though the reverse is also true in a few cases.

Pacifists don't like being dragged into Offensive Wars

The pacifists don’t like being forced into offensive wars.

Empires can propose a change in terms with a five year cooldown at a cost of some Influence. Exact costs are still being adjusted.

Proposal from our vassal

We are feeling beneficent today, and want you to catch up to us faster, Protectorate.

How can you influence them into accepting your generous offer? Giving them a good deal is certainly helpful, and just like before, empire relations and relative power go a long way as well.

The terms themselves are heavily moddable, I look forward to seeing what some of you come up with.

The Benefits of Loyalty​

Loyalty is the “currency” used between overlord and subject, and while the Specialist empires make more use of it than regular vassals, it’s still beneficial to keep your minions loyal since it gives you more options. Loyalty is largely determined by the contract between overlord and subject, but ethical compatibility will come into play as well.

Loyal vassals will agree to more onerous terms during negotiations, and will generally support their overlord. You can also “spend” their loyalty as part of trade agreements, strong-arming them into granting you better than normal trades.

You can request a public Pledge of Loyalty to you from a loyal vassal, making them even more loyal over time.

Pledge Loyalty

Pledge Loyalty has greater effects if the subject actually likes you for some reason.

Disloyal vassals will look for ways to be free of your tyranny, seizing the chance for rebellion should you falter.

They may also swear Secret Fealty to one of your rivals in hopes that they’ll be able to follow them in an Allegiance War.

Pledge Secret Fealty

In an Allegiance War, you seek to wrest control of the vassals that have pledged Secret Fealty to you, and they will join in on the attack on their former Overlord.

Gotta Subjugate Them All​


Like herding cats, having many vassals is hard work. Constantly vying for your attention, keeping multiple subjects happy can be difficult as jealousy ruins everything. “Divided Patronage” is a modifier that reduces the loyalty of all of your vassals, and increases based on the number of vassals you have.

You can mitigate this by offering them better terms, or by taking a vassalization related civic or the Shared Destiny ascension perk.

Franchising


Shared Destiny

Overlord Holdings​

In Cepheus, we’re expanding the branch office system from MegaCorp to be more flexible.
The corporate tab on planets is being replaced with a more versatile “Holdings” tab. For now, we have corporate and overlord holdings available here, but we have more future plans for this screen.

Much like branch office buildings, holdings are built on another empire’s colonies and can provide benefits to both empires. Much like criminal syndicate branch office buildings, some holdings might be far more beneficial to one side than the other. Each particular holding is planet-unique,

Corporate overlords can build both holdings and branch offices on their subjects’ colonies.

Holdings (Ministry of Truth)

The Ministry of Truth provides two Overlord Propagandist jobs to the planet, which turn the subject’s Unity into Influence for their overlord…

Material Ministry

…While holdings like the Material Ministry are disliked by subjects as the overlord claims a portion of the planet’s production for themselves…

Aid Agency

…Still others, like the Aid Agency, are welcomed on the planet.

Splinter Hive

Hive overlords can build the most universally disliked holding (tied with one other), which takes a portion of the subject’s planet and dedicates it to a spawning complex.

We’re also adding some holdings associated with civics or origins.

Noble Chateaus

The Noble Chateaus of the Aristocratic Elite allow them to send troublemakers off to bother someone else’s planet instead of their own, much to the dismay of their hosts…

Communal Housing Outreach

…Shared Burdens empires can spread their message through Communal Housing projects. How this is received depends largely on the ethics of the subject…

Gaia Seeder Outpot

…And Gaia Seeders, who are gaining more terraforming flexibility in Cepheus as described in Dev Diary #243, can also beautify the worlds of their subjects. The subjects tend to like that - unless they’re Hydrocentric, of course.

Since there are over twenty different holdings, I’ll share some more in next week’s dev diary (including a machine specific one), and some more on social media as the Overlord reveals continue (though I’ll repost those in that week’s dev diaries as well).

It’s a very versatile system that we look forward to exploring more in the future.

The Future is Ours​


That’s long enough for today. Next week we’ll talk about the advanced form of vassalization coming in Overlord called Specialist Empires.

Also, starting with this dev diary, we’re creating video versions on the Stellaris Official YouTube Channel for those of you that prefer listening to them. Subscribe so you don’t miss them, and let us know what you think!

The resource buildings are per job, so you already get a much bigger bonus for putting them on the right planet.

I'm curious if this suggests a coming change to Branch Office buildings. A suggestion/idea I sketched out some time ago was to change branch offices to a scaling-reward-by-job-type, with a emphasis on giving the client a reason to build the jobs your branch office building supported. That was mostly in a 'discount' format, but if a job-modifier is viable, I could easily see that as well.

So say that a Overlord mining building takes minerals from the subject to give to the overlord, but the megacorp mining building just gives minerals to the mining jobs, while giving a % of the minerals produced as 'free income.' Combined, a MegaCorp overlord could offset its own mineral production impacts to the vassal, while boosting its own take.

Shouldn't Noble Chateaus be redesigned a bit? Stability is hardly a problem on my capital worlds, especially when running aristocracy, so this just seems like an easy way to needlessly piss off your vassals without any tangible benefit. Maybe just make it the authoritarian version of a communal housing outreach, providing more amenities/unity/stability some ethics attraction and a lot less housing?

The "Holdings" tab appears to replace the "Corporate" tab. If someone used a Megacorp civic like "Franchising", how would the "Holdings" tab interact with the "Corporate" tab? Would one replace the other?
 
Wait a minute! If we can live off of vassals' resources that means we can actually use Chemical Bliss with our own main species and live a life of absolute decadence! This is going to be interesting for role-playing.

Can we use fleets to “persuade” our vassals accept terms even the Loyalty is not enough? Even this may means lower relation
Honestly, it's hard to care the feeling of empires that much weaker than me. They can't get the thing that can't get from battlefield on the negotiating table.
 
The changes announced thus far look neat.

Any chance we could get unique buildings for the really specialized planet designations (resort, prison and thrall worlds)? Feels like it would be a way to make them feel more unique, possibly make prison worlds worth designating and not sure about how thrall worlds stand (refuse to do slavery builds). Actually, I don't even think the AI makes them, so maybe could be a way to make the AI feel it might be worth having them.

Also are we limited to having holding on three worlds with two buildings each? Or does holding mean specifically the buildings and we are limited to only three in each subject, but can have up to two of them on a subject world?
 
Looks good!

As holdings are similar to branch offices and will be displayed on the same tab will it be possible to have holdings on a planet where another empire has branch offices? Also, Megacorp overlords should be able to forbid their subsidiaries commercial pacts with other megacorps so these can't build branch offices on subsidiary planets. It seems weird to me that this is already not part of subsidiary mechanic as branch offices are pretty central to Megacorp play.
 
I hope we get more control over sector design. You have to do all sorts of trickeries (such as deleting starbases) to be able to release a single system instead of an entire sector. If I want to release just a couple of systems with a few planets as vassals, I don't want to lose a nearby important planet that happes to be in the same sector.

It is nice that there seems to be a nice balance of benefits and noticable drawbacks to the contract options.

Though, I have a question in regards to a comment made in this Dev Diary:

Previously in Stellaris, subjugation was rarely a more compelling option than simple conquest
Are there any intentions to make ultra-aggressive expansion by conquest in to a less ideal option for civilisations that may not befit this approach? Or is the intend to only expand subjugation in to a more compelling option?

Regardless, the things mentioned in this Dev Diary look very nice.

You can build both Branch Offices (if the subject is a non-corporate, non-gestalt empire) and Overlord Holdings on your subjects' planets!

In fact, the Franchise HQ holding requires that you have a branch office open on the planet.

The sector customization we used to have needs to be re-instated ASAP. The lack of control over the shapes of sectors is infuriating, especially when it used to be as simple as clicking on the map to move systems from one sector to a neighboring one within overlapping range.

Just to make sure, when a subject swears secret fealty to someone will that be hidden from other empires or visible like normal diplomatic relations? And is there a way for the overlord to find out about it?

Seeing as the DD doesn't have any info on the Bulwark vassal type, this statement seems a bit premature
Yes, I hope you're right.

But my concern is because of the way the DD is phrased.

This quote in particular:

Some subject types have fixed, minimum, or maximum terms - Tributaries, Subsidiaries, and Prospectoria, for example, must always provide their overlord at least 30% of their basic resources (energy, minerals, and food) in tribute.

The sliders shown on the screen appear to apply to the subject types shown in the screen as well . And granted, the screen does have the scroll option which implies that there are more terms and conditions to negotiate between overlord and vassals, there is no mention or hint of naval cap contribution.

You can map out which vassal type's primary contribution is based on the screen; i.e Prospectia: minimum resources, Scholaria: minimum Research. Applying that logic, Bulwarks would be likely to have their war options locked to all wars instead of having the option to fighting defensive or offensive only.

You're right though, it is premature to judge based on 2 screenshots. But if the resource sliders could be shown, why not the naval cap contribution too? Something like that would have been a good teaser whilst holding off further details for a future DD.

Okay but can we force our vassals to give us their species for Xeno-Compatibility? This is very important!

My favorite part of playing as a megacorp is the branch offices, so I am looking forward to holdings. I also look forward to being able to play a "benevolent" hive mind after the update. I was thinking though that the war policy part of the vassal contract would be a nice thing to add to crusader kings. Having a Duke or count ignoring a war for their land because their king is the war target just doesn't feel right.
 
Will overlords have any ability to shape what ascension path vassals take?

Example if you have an assimilation citizenship from Psi or synth ascension can you share this new state of being with your subjects, or contrawise if a spiritualist overlord rules a materialist vassal can they confine those subjects to flesh? Could they end out allowing augmetics but not full transcendence and then mandating psi development?
