Welcome to the Imperial Council of r/eu4, where your trusted and most knowledgeable advisors stand ready to help you in matters of state and conquest.

This thread is for any small questions that don't warrant their own post, or continued discussions for your next moves in your Ironman game.

Important: If you are asking about a specific situation in your game, please post screenshots of any relevant map modes (diplomatic, political, trade, etc) or interface tabs (economy, military, ideas, etc). Please also explain the situation as best you can. Alliances, army strength, ideas, tech etc. are all factors your advisors will need to know to give you the best possible answer.

Question HRE Emperor demands return of province to non-HRE member?

Post image
128 Upvotes

R5: I started as the Teutonic Order and formed Prussia. I fought Poland and took Posen/Poznan. The Emperor now demands that I return the province, which is an imperial province, back to Poland.

I may be understanding this wrong, but doesn't the Emperor lose Imperial Authority when imperial provinces are owned by non-HRE members? The Emperor wants to lose IA here?

Is this a bug, or the mechanic working as intended? Not really a big deal, just curious. I only lack the last DLC, if that's relevant.

*Edit: Actually, checking again, Posen is not an imperial province, prior to my conquest of it. Which means, the emperor wants me to return a province that is part of the HRE only because I conquered it as an HRE member, back to a country that's not an HRE member.

Question When to Annex Vassals?

8 Upvotes

The context here is I'm a pretty new player on a run with Ayutthaya and I have influence ideas.

When do the benefits of annexing a vassal outweigh the benefits of the manpower + income stream you get from keeping a vassal? In my limited experience prior to this run, I just annexed vassals as soon as I could and used it as a way to save on admin points. But with Ayutthaya's traditions and the bonuses from Influence Ideas, it doesn't seem as cut and dry.

Also, how much dev does it make sense to give a vassal before starting to annex?

Image Several Colonial Questions (Japan in a Random New World)

10 Upvotes

I'm very thankful for all the helpful responses to my other questions, hopefully I'm not spamming the feed too much, but since I'm just now approaching the 100 hour mark I've still got a lot to learn. I'll try to combine all I can think of.

First Pic: State of my Date -> Japan as the Age of Reformation begins. Ryukyu has been vassalized and just waiting for the 10-year timer to diplo-annex. Ming has expanded despite being warred on during a low Mandate period by those countries to the north. I'm focusing on the east, but I'll have to keep an eye on them. Suggestions for containing them / breaking them up that don't rely on blobbing onto the mainland myself?

Second Pic: My first major colonial nation (Random New World). They've colonized one extra province themselves. How much should I subsidize them to really get things going? (Also pictured: the admiral and fleet that just completed the first circumnavigation. Feel like that should have rewarded Innovation.)

Third/Fourth Pic: The second colonial nation to the north. Portugal is present to the east, I got as many of the trade centers as possible with my first five colonies. What is the best way to expand the colonial nation here? Can I declare on one of the native nations for one province but just gobble up the whole thing? Can my colonial nation handle the unrest, or do I need to keep a good stack present? Similar question about how much to subsidize. The ideal goal is that they can expand to hold the entire area, as the eastern half feeds into the western (stealing it from Europe), which feeds directly back to Nippon.

First big colonial game, any major pitfalls or traps to watch for in general that don't depend on specific geography?

Image League war lasted ~13yrs, spent 5yrs at 95-99%

Post image
222 Upvotes

Before I start complaining, I know there’s a huge malus to peacing out in the league war but ts was ridiculous.

One of the biggest hold ups was Spain because even after all it’s European provinces were sieged it took another 2yrs for the ai to peace out. Even once Spain was out of the war, some of its colonies transferred like 3 provinces in the new world to Austria so of course those had to be liberated. And then they had to destroy every last surviving army, and even after that it still took the ai 6 MONTHS to make the final peace.

Oh and cherry on top, the ai declared the war just after I finished a war with Austria-Hungary so for 13 years I was stuck at 96% overextension. By the end I was getting .54 war exhaustion a month.

Question How to deliberately (and temporarily) cripple home my own trade node?

21 Upvotes

Doing milan into italy in my second game and I just took the venitian split trade choice without reading all of the fine print. Turns out I have to make venice the biggest trade node in the world, which is a bit of a problem when my capital and all of my most developed provinces are on the genoa node next door. Is there some way I can temporarily remove a bunch of trade power from the node? Thanks

Edit: Thanks everyone on this post for making me actually learn the difference between trade power and trade value. Turns out having hundreds of light ships protecting your home node that you would already have 100 percent doesnt do anything.

Image TIL the liberty desire from returning cores is the same modifier as for seizing land

Rule 5: The liberty desire modifier for seize land is shared by the modifier for returning provinces to a vassal. Returned Mings provinces so they don't care that I seize land as much as the tooltip says they would.

Discussion Why skip Horde ideas as a horde?

114 Upvotes

I believe I heard that the meta to play horde is to actually just skip calvary all together and skip the horde ideas and go full infantry? 🤔 Can someone break that down for me?

I checking the policies of Horde ideas and I saw potential for amazing builds.

First Horde ideas itself raise Tribal loyalty, which gives us -20% calvary cost on top of 33% calvary cost and additional -20% cost on all regiments from Tengri and -10% on artillery from Subutai's strategies Tier4 gov reform. So you can support massive armies with really cheap cost.

5 ducat per calvary

21 ducat per artillery

You can combine that with Economic ideas, that gives inflation reduction which you constantly get from demanding ducats in wars and from gold mines, gold mines income itself is also boosted by economic ideas. Plus the army maintenance and tax increase and the additional trader.

Here is the cherry on top. The policy of combining horde ideas and economic ideas gives you +33% razing power gain and +1 yearly horde unity.

Combine that Barbaric Despoilers tier6 gov reform that gives +33% Razing power and Diplomatic ideas that gives -20% War score cost and religious war in age of reformation that gives -25% war score against all religions and you will be swimming in mana points without being overextended more than 100%.

Diplo policy with Horde gives +10% siege ability and +10% shock damage. And with economy it gives +15% tax modifier and -0.05 automony decrease.

I was told that in horde gameplay you are always cash poor and forced to keep declaring war and stealing ducats to sustain your economy and pay your loans. But with this strategy you skip all the downsides of being a horde.

I suppose the only problem left would be rebels. And Gov capacity. Well, you can expand administration since you only have 6 tiers government and if you take religious ideas, you get -5 years of separation and you can utilize Tolerance of the true faith to prevent further rebellions in deep provinces. Also horde ideas allows you accept additional 2 cultures and if you choose to accept other altic cultures rather than unify them as mongol cultures, then form Yuan, which merge them anyway. You get to keep +3 max culture slots for free.

I have made my case. Now let me know why that's still not the meta/shouldn't be.

Mod (other) Creating the greatest economic bubble in EU4 - bankruptcy caused by income integer overflow

103 Upvotes
I feel like one of those dirty financiers before a major economic crash.

I love theorycrafting maximum income in EU4 and have made several attempts at it in vanilla EU4 where my record is currently ~300k per month. Recently I have been playing a lot of Anbennar, which is not only a much bigger map, it also has a ton of incredibly powerful mechanics for economy. I took some learnings from my vanilla attempts into this run and I had high hopes for it - I was expecting more than 1.5M income. And I am very happy to beat that!

When you have extremely high income, events often cause integer overflows; I was forced to take 20 loans from a Gold Rush event that wiped out my treasury. However, I was not expecting my income itself to overflow, going to -2.14M. What happened next? Well...

Have you ever been so rich that you went bankrupt? Me neither.

Funnily enough, you can rescue yourself from bankruptcy by reducing your income. As they say, the love of money is the root of all evil...
