Europa Universalis IV - Development Diary 28th of June 2022

Dzień dobry! Welcome to today’s developer diary! We will be taking a first look at the new Polish, Lithuanian and Commonwealth trees!

But first, allow me to introduce myself. I am Big Boss, the newest addition to the Content Design team. I started playing Europa Universalis during 2011 and have loved spending time looking at and painting maps since then. More recently, I have been working on several mods, so some of you may know me from my work there. I am genuinely very excited to share with you all the hard work the team has been putting into this update and praise the immense amounts of support I have received from my new colleagues and mentors! As we delve into this developer diary, please keep in mind that the icons and event images as well as numbers displayed are by no means final!

The beginning of the game finds Poland rudderless, with her King, who maintained a union over Lithuania, Hungary and Croatia, having died a mere day earlier, after risking his fate against the Ottomans at the battlefield of Varna. Thus, Poland starts at a quite precarious state: a vacant throne, the Nobility’s Golden Liberty in full effect, and surrounded by powerful neighbors. At the same time, the Ottomans in the South and the Muscovites in the East are taking great steps to consolidate and expand their domain.

So what’s new for Poland? For starters, they have access to two new T1 Government reforms. The first one is the Great Sejm reform, granted to them at game start:

2.png

Bear in mind that any and all numbers you see in this Developer Diary are strictly work-in-progress and are subject to change, especially in response to valuable feedback from the community!

The second T1 reform is a special reform for Poland upon accepting the Union with Lithuania:

image (30).png

Unlike the Great Sejm reform, the Polish Elective Monarchy grants the ability to elect various princes to the throne, a steeper absolutism malus and, similarly to the Great Sejm, it enables the Parliament and grants a reduced Unrest bonus.

Speaking of the union with Lithuania, it should be noted that some changes were made to that event. Now, it will fire even if Lithuania is a player. A Player Lithuania will be able to decline, but AI Lithuania will always accept. This was done in order to further facilitate the idea that Poland and Lithuania make a great co-op campaign, which is also complimented by both mission trees granting bonuses that follow the spirit of cooperation between the two nations. Here’s how the new event plays out:

3.png

4.png
To further immerse the players into the gravity of their choices, I went ahead and added a few dynamic missions for Poland, based on your choice between the local noble or the Lithuanian PU. Accepting the Lithuanian union will lead you towards developing the Lithuanian core as well as elevating their nation financially and (later on) artistically as you prepare them for the eventual integration:

5.png

6.png
This branch ends with you declaring the Imperial Commonwealth, which grants a powerful temporary bonus:

7.png

On the other side, declining the PU with Lithuania will grant you the path that leads you towards the West via entering the Empire, leading it and passing reforms.

8.png

Note: You will still receive claims on Lithuania and be able to form the Commonwealth!
The first mission’s reward is an event for the current Emperor to admit you in the Empire:
31.png
This path will also contain new and innovative rewards such as the new modifier ‘Reasons to Elect’:

0.png

The final mission for the Imperial path of the West will imbue Poland with a sizeable bonus to their Imperial Authority Gain as well as extra Diplomatic skills for her ruler.

Main Body of the Polish Tree​

Addressing the aftermath of the Varna crusade will have a profound impact on the rest of the missions further below. Opting to pursue friendship with Hungary and/or Bohemia will lead both parties to a shared sphere of prosperity, historical friendship and powerful bonuses to last as long as the alliance is maintained. However, should you choose to rival and become antagonistic towards them, the reward will switch to a PU CB / Permanent Claims based on the country’s union eligibility. To be clear; you can pursue friendship with one of them and antagonize the other, the choice rests entirely with you!

2Yf_ckUJUFNu5aCHKpYrLOTQczg4pZzdcIS-4tR7vAYoe3dei43MniG3iVD83F9PKO6G-QlzgVIP9iFqq46ahbZJzb8vDx39qBWs4NN1bTJxoQRVQEhoEIHAL477R9zEdo6Qm7VEpX1GFcYvJGQ

Internally, Poland needs to address the growing influence of the nobility. Regarding that, in the mission ‘Leverage the Magnates’, you are granted the opportunity to cooperate with them and win their favor via great concessions or directly oppose them. Keep in mind that due to their tremendous influence, opposing them is quite difficult. Working alongside them will reduce the cost of Parliamentary Bribes (which will be increased by default for 1.34) and grants a small Loyalty bonus until you pass further legislation as the Commonwealth to reduce their authority. Alternatively, if you dare to oppose their authority, you will gain an event to face a major uprising of Magnates that will also reward you with a unique new modifier:

image (42).png
The missions directly below it follow the turbulent history of Poland and will have you attempt to pass legislation and reform the government by undoing nobility influence. Choosing to oppose the nobles in the mission shown above will also impact the following few missions!

The mission ‘Great Sejm’ will unlock a new personality type ‘Reformist’ which grants more reform progress growth as well as new unique Parliamentary Issues for Poland! The new personality can be assigned to all rulers with at least 4 Administrative Skill.

Resolving the matter of Hungary and Bohemia will yield dynamic rewards based on whether you completed them via conquest or diplomacy. This also impacts the reward for ‘Balance the Princely Lands’:

14.png

Moving on, you will also be tasked with harnessing the Polish Renaissance, dealing with the Piasts of Mazovia and developing Krakow:

image (31).png

image (32).png

On the Conquest front, you will be led towards quelling Roman’s Rebellion in the South and seizing control of Wallachia, raising troops from nobility strongholds and assisting the Prussian Confederation:

15.png

17.png

18.png

Note: Assisting the Danzig merchants may lead to the formation of Royal Prussia as a subject under the Polish crown which will have its own few missions to break free from your hold!

Of course, the Polish tree holds many many more cool new additions, events and rewards and they are up to you to discover!

Finally, Poland (and the Commonwealth in general) will have access to a new special unit, the Winged Hussars! I am very excited to finally talk about this new unit.
  • They will be available for Poland and PLC via a national idea
  • In our current build you may recruit 1 Winged Hussar per 100 Development
  • They come armed with +1 Cavalry Shock and +100% Reinforcement Cost
  • They are further empowered by your choices in the mission tree!

image (33).png

The Winged Hussars have arrived!

As a side note, we currently have not chosen yet what colour the Carolean and Hussar unitbox will have. Janissaries are red, Cossacks are orange. Feel free to suggest potential colours!

The Lithuanian Mission Tree​

Alongside Poland, Lithuania will be getting her very own missions. It builds upon the old mission tree and greatly expands it, honing and improving upon the unique aspects of playing as Lithuania:

19.png

Among the highlights of the Lithuanian tree are the ability to call upon a host of Cossacks, new unique T1 Government reforms (yes, plural!) and the potential to utilize the Tribes Estate for a limited time.

21.png

22.png

23.png
Alongside these new additions, Lithuania will gain access to new events and flavor:

24.png
If you choose to remain as Lithuania for a little longer beyond Administrative Tech 10, we made sure to accommodate your stay with flavorful missions that will entice you to stick around a while in order to get all the rewards and complete the tree:

25.png

The Commonwealth​

Building upon the solid foundation that is the Polish mission tree, Commonwealth missions originally appear as part of the Polish tree, marked as “Locked Missions”. Unlike other formables, we took the creative decision to showcase the Commonwealth tree to the Polish player, before accessing it. The reason behind this is to prepare the player for whatever challenges and requirements the PLC missions will ask for and ensure the player is not caught off guard.

Thus, if you hover your mouse over the Locked Missions, you will see the requirements as well as potential rewards beforehand.

Now that’s out of the way, let’s take a look at some of the missions we have in store for the Commonwealth, starting with this one, my favorite, ‘A Lifetime of War’

10.png

26.png
Note; Since the mission only requires one of the listed requirements for it to be completed, you may see fewer choices in your version of the event, based on which way you choose to complete the mission. Shape and sharpen your army the way you want to!

Note: Please be aware that these numbers are not final!

A PLC tree would not be complete without its ‘Invest in Eastern Poland’ Mission, which requires you to have 40 provinces with a manufactory or a level 3 Center of Trade and either 40% Global Trade Goods Produced or 7 ‘Trading-in’ Bonuses. Here is the reward:

image (34).png

Following in the steps made before forming the PLC, and after completing the Great Sejm mission, you will gain access to flavor missions that will assist you in passing and repealing the Articles of Agreement (Pacta Conventa) and even rewriting them completely from scratch, with more favorable terms on the behest of the monarch, if you chose to oppose the Magnates in a previous mission:

27.png

The conclusion of the major flavor part of the tree is the mission ‘Dominate the Markets’ which grants a new mechanic we made specifically for the PLC, the ability to reset or extend a Golden Era:

image (38).png

image (35).png

External Affairs of the Commonwealth​

No major mission tree would be complete without a robust conquest path. That much is true for the PLC, which will be granted missions, a new Casus Belli and even gain Streltsy as a one-time reward from one of their missions:

image (36).png

image (37).png

29.png
Moving on, ‘Prevent the Deluge’ will task you with dealing with whoever the ruler of Scandinavia is, be it Sweden or anyone else. You may deal with them in a multitude of ways, including diplomacy or conquest. Should you choose to approach Sweden diplomatically, both nations will be positively impacted by a wave of prosperity. Sweden will gain +25% increased production for its metals and historical friendship while you will gain direct access to Scandinavian copper and iron, reducing your overall military costs:

28.png

The final conquest mission for the Commonwealth will set you up to become a supreme great power, requiring you to be a hegemon and have a tremendous amount of development under your belt:

30.png

Note: Development Efficiency’s number will be green in the final build!

The philosophy of the PLC missions is that of a tree whose content should last the average player till around the 1700s at the very least, so expect a lot of hard work and very worthwhile rewards from every single mission in this tree!

While we are on the subject of the Commonwealth, I would like to showcase some new implementations that the team worked hard for. As I mentioned above, the PLC will now enjoy a lot of new content including 2 different sets of National Ideas. One for nations whose primary culture is Lithuanian and one whose primary culture is not Lithuanian (namely Poland as an example):

Polish PLC Ideaset:

Code:
PLC_ideas = {
    start = {
        nobles_loyalty_modifier = 0.1
        num_accepted_cultures = 2
    }
 
    bonus = {
        monthly_reform_progress_modifier = 0.25
    }
 
    trigger = {
        tag = PLC
        NOT = { primary_culture = lithuanian }
    }
    free = yes
 
    plc_prosperous_folwarks = {
        global_trade_goods_size_modifier = 0.10
    }
    pol_jagiellonian_university = {
        idea_cost = -0.10
    }
    plc_the_obrona_potoczna = {
        drill_gain_modifier = 0.25
        army_tradition = 1
    }
    pol_winged_hussars = {
        cavalry_power = 0.3
        can_recruit_hussars = yes
    }
    plc_refine_our_golden_liberty = {
        monarch_admin_power = 1
    }
    pol_royal_guards = {
        infantry_power = 0.10
    }
    plc_tempered_by_neighbors = {
        discipline = 0.05
    }
}


Lithuanian PLC Ideaset:

Code:
PLC_LIT_ideas = {
    start = {
        global_manpower_modifier = 0.25
        tolerance_heretic = 3
    }
 
    bonus = {
        governing_capacity_modifier = 0.15
    }
 
    trigger = {
        tag = PLC
        primary_culture = lithuanian
    }
    free = yes
 
    warlord_dukes = {
        max_hostile_attrition = 1
    }
    plc_tempered_by_neighbors = {
        discipline = 0.05
    }
    new_magdeburg_laws = {
        development_cost = -0.1
        global_trade_goods_size_modifier = 0.05
    }
    reciprocal_guarantee_of_two_nations = {
        all_estate_loyalty_equilibrium = 0.05
        diplomatic_annexation_cost = -0.15
    }
    lithuanian_hussars = {
        cavalry_power = 0.2
        can_recruit_hussars = yes
    }
    statutes_of_lithuania = {
        global_unrest = -2
    }
    lithuanian_renaissance = {
        technology_cost = -0.05
    }
}

Special thanks to Verinity Void whose National Ideas work was partially adopted for the Polish PLC ideaset!

I am at your disposal for any questions you may have about the trees, as I’d love to read and answer your feedback, and also feel free to suggest tweaks as well. Thank you for taking the time to read my very first Developer Diary! Next week my colleague @Ogele will come back, to talk about some sea-related new content.

Where do you have such requirement? I remember only that junior partner can't be to big for free integration when going diplomatic way
Last time i played as Poland and tryed to form PLC i had some restriction because my Lithuania (junior partner) was to big. I couldn't form PLC so i had to lose some provinces intentionaly.
 
Note: Assisting the Danzig merchants may lead to the formation of Royal Prussia as a subject under the Polish crown which will have its own few missions to break free from your hold!
I hope you'll add some interaction with Brandenberg to trigger/boost this, as it's hella frustrating to try a Prussia formation game as them and then just spend 100 years staring at the PLC while I wait for someone big to oppose them because they ate the Teutons before I could

My wish is that there could be content related to the Cossacks and Rus, more than just cursory missions about development and an estate modifier. Historically, they were a major player and were responsible for the loss of the core of Rus, which would then be snatched up by Moscow. A man can hope.

Hello there.

I decided to give some suggestions, even though I might repeat what others said, I will say it anyway.

1. Winged Hussars should be absolutely overpowered, they must be like a cavalry of space marines, but very small in numbers. I really like that they are rare, only 1k per 100 dev, that is accurate, because in Commonwealth, there was only a few thousands of them. They were the elites among the elite, and every "szlachcic" wanted to have that prestige. Sadly I don't think that +1 Cav Shock gives them justice. I know You said that they can get bonuses via missions, but what are the other bonuses we can get? Right now we've only seen "Elite Hussar Cavalry" with "-20 fire damage received" which is ok, but in comparison, "Cavalry with a state" looks like much better choice, because it allows to build full cavalry armies. I think that Winged Hussars should either get more base buffs, or the mission reward "Hussars Only" buff should be given right away after completion, without having to choose between upgrading only Hussars or upgrading the cavalry as a whole.
Buffing base WH could be balanced by making them really slow to reinforce, I think someone already said it on this thread.
TLDR: Please make Hussars stronger.

2. Commonwealth's Economic Hegemony bonus looks weaker compared to other two, because this one is only for 25 years, while others are permanent. Can we expect this bonus to be made permanent too?

3. I know that Lithuanian PLC gets tolerance of heretics, but I think PLC should get it no matter who forms it, maybe by mission or the decision. Commonwealth during its golden age was known as a place of tolerance and haven for many people.

Polands national ideas are a prime reason why they can hold Russia and Ottomans at bay even without a strong alliance network. Now they will lose it upon forming Commonwealth, giving Russia and Ottomans a reason to simply eat them.
The prime reason Poland can hold them at bay is because it is a pre-formed very large blob.
Since AI Denmark will on average very likely lose their PUs early on in the new version, then it really looks like this update is made for players and will terribly missfire in the hands of the AI.
I do hope Norway is less likely to go the independence route, but I don't really see what the problem here is. Multiple tags have competing missions and ideas. Denmark succeeding is an ahistorical outlier outcome. It not happening often is fine.
If we are still in the position where we have to fight fair wars, i would gladly give any economic bonus for more Morale and Disciplin. Getting more stuff = getting more rich.
Lacking combat bonuses is not going to make a player fight less wars or try to hold less land. At that point extra admin is faster coring. The war exhaustion I would give you, but the cost of war exhaustion is the least valuable mana.
So it seems that new PLC ideas are much weaker in terms of Warfare. Losing 15% morale, 25% manpower and monthly war exaustion reduction is huge.
My question to the devs, was it nerfed on purpouse bcs the new mission/events will give PLC some of those bonuses back? Would PLC be too op with old ideas and all the new content?

From my point of view the PLC as it existed before hardly ever formed in the hands of the AI and when it did Poland completely steamrolled, blobbing all over Europe and taking over Anatolia etc. In a player's hand PLC as one of the most powerful early starts in the game and is guaranteed to be one of the strongest countries in the game with low risk. (sidenote heroes, I thought you got hit a little too hard with the disagrees)

I guess what I would say to all the questions about the point in the game you use the ideas is: If you do want the PLC ideas but you feel like you might want to wait until late game you can always just... not press the formation button as soon as it pops up.

That's the only restriction and it's the same for Spain or Great Britain - subject can't be to big or you have to integrate using dip points like normal vassal or junior partner.
Without this requirement I can play as Poland and give all new provinces to Lithuania, they will core it falling behind in admin tech and I would be able to integrate 100 or more provinces for free? Or I get late game PU on much stronger Lithuania and integrate instantly?
Currently you can give 9 more provinces to Lithuania before it becomes to big, new mission tree transfers some provinces from Lithuania to Poland with free cores so you will be able to give them about 20 provinces before they are over the limit.

I think the idea is more Polish and the Polish idea is more Polish–Lithuanian Commonwealth.
Hopefully the developers will switch ideas, otherwise no one will want to set up a Polish–Lithuanian Commonwealth in a multiplayer game, and the Austrians will set up a Polish that will not survive.

I think Poland changes are interesting, but I hoped that Lithuania wuold have a few vassal in 1444 (for instance duchy of Kiev, Smolensk etc)

Maybe they don't want this because it slows Muscovy down?

1) Muscovy releases those nations for faster expansion

2) The stronger Poland gets (and a stronger Lithuania is a stronger Poland) the less chance of Russia forming.

3) A lithuania player can simply release those nations as vassals at game start

It was always prohibited, hence why you need event chain to swap out
Isn't the subject regarding the sale of Neumark event.
'prussia formation' doesnt require numark iirc, just starts the mission tree claims
 
Well thats a lot of stuff thats not even remotely balanced.
I approve, gonna have som fun campaigns with this DLC.
They have jumped the shark with this DLC. I can imagine every country not Sweden or Poland saying 'wtf... are you kidding me?' when this dlc drops. Western europe is going to have hysterics and the Habsburgs may not even bother to show up.

A lot of this stuff is op as hell, but then Lithuanian PLC gets a religious tolerance bonus when it's gov. reform already completely takes care of that? Or do you lose that gov. reform and risk a huge religious uprising from the loss of bonuses when you form PLC? Either way it's bad

But theyre so low dev, and due to being an empire you have high gov capacity so would want to conquer, especially with your permaclaims

Poland needs to resist buffed denmark and Sweden, russia likely getting buffs too this patch
3) A lithuania player can simply release those nations as vassals at game start
A french player could always release vassals but they still decided to start with them released in 1444 with 1.30

So I assume Musscovy/Russia is about to see some truly massive buffs to ensure at least some chance of the historic outcome where the PLC was removed from the world map during the game's time frame?

Which is crazy, because its still the strongest nation in the hands of the player.

But we may not see Russia forming anymore if something is not done.

Maybe the requirements for Russia need to be simply that Nov or Muscovy (one or the other) do not exist, if Muscovy or Nov, or both do not exist if a Russian minor, and tech 10.
