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:

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:

XusG-PJ1TI34J6kO-2wWh9wpZ1shqmJ-wYxX6I3FbITFJ8Z7mw29ZDBACb_XWZfxdTRZb7QHD1ezgf5hza0yh_ejy8tjVBCYzllSuVsP9KbfOaJfHfYu_IYwwcMQV7zbZCpv0QjYvtnM8zYAcM8

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.

Can Mazovia form Commonwealth without the need to form Poland? I did a little bit of a research and there's nothing that indicates that Mazovia can or can't do it.

I think you can't form Commonwealth directly, you need to form Poland first so it will always be Poland or Lithuania who forms it
Also another thing that kicked me is if you can culture shift. So lets say that you're playing as Austria, culture shift to Polish, if there are no restrictions you could form "Commonwealth".

Appologies and thanks mate. I do play EU4 on my laptop and curently i'm on vacation so i didn't bring it with me. The only source i do have are other forums and EU4wiki.

Ok so there's a decision "Enforce Polish - Lithuanian Commonwealth".

Potential requirements
The Commonwealth does not exist.
The country:

Poland and Lithuania are not in a personal union together
If the country is not AI-controlled then:

Playing with normal or historical nations

So if i'm reading the last line right both Poland and Lithuania must not exist. You must have certain provinces and i presume that you'll have to culture shift to either Polish or Lithuanian. Or my understanding is wrong.

On the topic of tweaks and communication, please remember we have already said "No New Tags" introduced in the game. The reason behind this is that new tags (even when not active) pose a great strain on the performance of the game. I really wanted to have the Latin Empire appear as its own tag but for now it's just Byzantium with another name (or perhaps a modifier if you are Catholic?) and *potentially* Crusader ideas (based on whether or not you will like this suggestion!)
Let me know what you think and what the best way to tackle this issue might be, from your perspective!

I honestly didn’t know dynamic names were a thing. Anyway, this is totally understandable, but I do want to suggest tweaking the mission tree for the Byzantines if Catholic.

One of them must not exist so when you are Lithuania Poland must not exist, when you are Poland Lithuania can't. And this is just for players so AI can form PLC when the other nation exists but still needs to be Poland or Lithuania from other condition

As a thank you for receiving such valuable feedback, I put in a little extra work and behold, forming the Commonwealth as Lithuania (regardless if you do it diplomatically or via war) will give you a pretty new name for you to map-paint with! Enjoy and thanks again for all the feedback and responses!

Hey man i love the new name. Will it be possible to have same result if you form PLC as Poland? Like "Polish - Lithuanian commonwealth".
That'd be cool. But if someone else forms the commonwealth, it will be called just "Commonwealth". Sound good ?
Please, don't change name from how it is simply "Commonwealth" now in-game. In Polish this state is most often called "Rzeczpospolita Obojga Narodów", which can be translated as "Commonwealth of Two Nations", name which doesn't really emphasize one union part over another. Current in-game name "Commonwealth" is similar in that regard, please don't change it.

But in English it's "Polish - Lithuanian commonwealth". In English you also call Japan - Japan, not Nippon or Nihon.

You have that backwards. Either ai=no (i.e. player) OR POL does not exist OR LIT does not exist so the player can form the Commonwealth while both nations exist but the ai can not.

[...] it now grants Own Territory Dice Roll Bonus +1 only [...]
I just wonder why that bonus specifically. What is it supposed to represent?

Perhaps Dice Roll Bonus +1 on allied besieged fortresses only? And call that bonus Antemurale Christianitatis?
More flavorful IMO, but that's just me.

On the topic of tweaks and communication, please remember we have already said "No New Tags" introduced in the game.
With love from Ogadeen and Wadai! :cool:

Some context for this reform: You are supposed to get it after repealing the nobility and the Golden Liberty, so expect it around the 1600s at the earliest.
1600 at the earliest? You mean when PLC historically started its slow fall? It needs at least a malus. I suggest to add something that will increase cossacks influence, so it will be more likely they revolt (Cf the Khmelnytsky Uprising).

Well.. Being french, it's gonna be "République des Deux Nations" or "République des Deux Nation", but good stuff nonetheless!

PDX Big Boss I am Polish and I know that everybody love Poland in Eu 4, but​

1) Can you remove 4 level forth from Giurgiu Mission. It's op in this stage of game. Some defensive bonuses wont be bad.
2) Remove Friend tag from Polish- Swedish relationship. We were mostly time rivals in Baltics sea. I happy that you gave subjugation and it's very good decision that You give some bonuses two countrys if they are friendly. I hope in future diaries we will see more relationship like that. It's great idea.
3) Winged Hussars should cost a lot. One Winged Hussars cost one Village that time. Secondary It's should be most op unit. Bigger prosperity or less devastation in province then Winged Hussars Stronger?. It would be similar mechanics too Militarization.
4) Can you give https://en.wikipedia.org/wiki/Khmelnytsky_Uprising( Zaporozhe rise) and Tatars raids( Upgrade border Friction event). Tatars often raid eastern part of PLC.
5) We will get Magnate Estate?. Richer Nobles. They had a lot power in PLC.


For more Thoughts I will give in weekend.

Edit: I learn something today about PLC. I did not know that we had advance fulling.

PLC and LPC love it.​

I don't recall asking for name change into "Rzeczpospolita", so you are arguing with yourself there.
Again you're using the name for Polish Lithuanian commonwealth in Polish "Rzeczpospolita". In English the country name for Rzeczpospolita is Polish Lithuanian commonwealth,PLC in short. Germany in English is Germany and Japan is Japan not Nippon or Nihon.

Edit : And no i'm not arguing with myself when i have you <3.

In Polish It"s "Rzeczyspolita Obojga Narodow". It's full name of PLC. Most funny thing is that there is no mention about
Poland and Lithuania, but PLC i LPC is easier to understand. You know who are they.

In Latin is "Res Publica Utriusque Nationis"

Nope, never heard of PLC and LPC :D. But when you say Poland and Lithuania or Polish Lithuanian commonwealth i do understand. And the previous name "Commonwealth"? Is it like British Commonwealth, since they have it as well, or Commonwealth of Independent States that was formed after the colapse of USSR, not sure if any other Commonwealth exists :D. But in all seriousnes it'll definitely be supercool to read "Polish Lithuanian commonwealth". In fact Poland is the first country i plan to play with next update 1.34 and DLC.

Germany and Japan arguments are irrelevant since I don't advocate to change name into polish one, so you are arguing with something I didn't say. Unless current name "Commonwealth" is not english enough?
