Seperate Warfare and Land/Naval Warfare[edit source]

Seems to me there is redundancy here. I propose Warfare covers all general aspects of war, how to begin and end one, for example, while everything related to land warfare gets moved to the Land Warfare site, and naval warfare to the respective Naval Warfare site Damarow (talk)

Yep. There's currently significant redundancy, mainly things that should be on the land warfare page. I've not had the time to address the issue, but I'd appreciate it if someone moved the appropriate sections over to the land warfare page. ~ Meneth (talk) 11:32, 16 August 2013 (CEST)
okay Damarow (talk) 13:09, 16 August 2013 (CEST)

Cause of War -> Extract part about relations?[edit source]

I just wonderd if the part about diplomatic views in the Cause of War -Part should be moved? Damarow (talk) 09:43, 29 August 2013 (CEST)

Yeah, it does seem rather out of place. ~ Meneth (talk) 09:45, 29 August 2013 (CEST)
Hm create a page called "Diplomativ View" maybe? Damarow (talk) 09:47, 29 August 2013 (CEST)
There's not all that much to say about it until someone figures out exactly how it works. A page called "relations" about most things that modify relations would make more sense. ~ Meneth (talk) 09:49, 29 August 2013 (CEST)
Sounds reasonable. Maybe include the content from agressive expansion as well? Damarow (talk) 09:52, 29 August 2013 (CEST)
Sure, AE could be merged into that page. Then the Diplomacy page could possibly be renamed to diplomatic actions, though just diplomacy works still, but is slightly more unclear. ~ Meneth (talk) 09:53, 29 August 2013 (CEST)

Annexation should go to the Vassals page?[edit source]

It makes more sense to have all info pertaining to annexation in the Vassals page. This page is not a very intuitive place to find it. Mindcorrosive (talk) 06:29, 3 September 2013 (CEST)

Yeah, it should be moved over there, with perhaps a link being left here saying something like "there are also some tricks that can be done using vassals". ~ Meneth (talk) 07:55, 3 September 2013 (CEST)

Ending a war - Province cost[edit source]

"Appears to be 8% + 2% per base tax + 2% per 1k base manpower." That cannot be right, can it? Even your screenshot shows provinces with lower costs. And I remember from fights against large nations (Ottomans), that you can get provinces for as low as 2% warscore ... Or maybe I am understanding something wrong what is meant by "province cost" --Lateralus (talk) 17:24, 17 September 2013 (CEST)

I've heard that if you hold a province for long enough during a war (5 years, apparently) its warscore cost lowers. I haven't been able to replicate that in my game, though. --The Overlord (talk) 18:16, 17 September 2013 (CEST)
I tested using vassalize costs with relatively small countries (< 10 provinces) at the very beginning of war. Defines.lua suggests that there's a reduction for prolonged occupation. I'll test larger countries with adjusting the null CB to allow individual provinces when I get home. --Evil4Zerggin (talk) 19:25, 17 September 2013 (CEST)
From what I've heard, the cost going down over time is not a mechanic that exists in EU4. I'm pretty sure it exists in Vic2 though, which is probably where people got the idea. ~ Meneth (talk) 19:51, 17 September 2013 (CEST)
According to DDRJake it does happen at least for vassalization: forum:709144. Really wish Paradox would add tooltips for how warscore costs are computed. --Evil4Zerggin (talk) 20:03, 17 September 2013 (CEST)

Testing[edit source]

  • By modifying Makassar to have three provinces with equal base tax and manpower, and declaring war with Brunei, it looks like Annex Province and Return Core has the same value.
  • With three provinces the full annex/vassalize seems to be capped at 387% no matter how high the base tax and manpower.
  • Below the cap the warscore cost seems to be 8% + 2% per base tax and kManpower.
  • Revoke core seems to be half as much, but the cap doesn't seem to work the same.
  • Releasing vassals that don't share a border with the other party seems to often be only 2% warscore per province.

--Evil4Zerggin (talk) 05:50, 18 September 2013 (CEST)

  • The cap seems to be 400% - 4% per province. Yes, the larger the country, the lower the warscore cap!...
  • ... up to a point. A country's full annexation cost cannot be lower than 2% per province.

--Evil4Zerggin (talk) 06:28, 18 September 2013 (CEST)

1.2[edit source]

Apparently they increased the country cap so that it's never below 400% (the cap, not the actual total warscore). Will need to do more testing.

about forced vassalization[edit source]

From what I've seen, forcing vassalization via war only possible if you've occupied the capital (however if another country occupies that capital - "forced vassalization" will be available for that country, not yours). Also I vassilazed a 2-province country just by occupying its capital without occupying another province - which means that this option doesn't have a "100% of provinces occupied" requirment.

dip cost[edit source]

For some reason I pay diplomatic power price for all annexed provinces, even though the diplomatic power cost is grayed out (because i transfered province sieges to vassals) and it even says, when I hover over it, that my vassal should pay it..

Please add proper diplocosts into the peace terms table. Although I think that UI isn't up to modern patches, since it says that it takes one number of diplocost(45) in the peace deal, but in reality it've taken 100+

Enforce military/naval access[edit source]

via sue for peace: does it cost anything (fleet basing)? does it take a diplomatic relation slot?

Yes, you need a diplomatic relation slot to maintain fleet basing. In advance "the base cost is 0.1 ducats per month per port, with a minimum of 0.5 ducats and maximum of 2.0 ducats. This fee is based on the count of permanent ports.The fee can be seen in the economy window under Harbor Fees." H4n1baL (talk) 22:11, 18 December 2014 (CET)

Truce[edit source]

there's a weird thing with truce.. april 1653, war goal: show superiority (expansionist finisher cb against asian nation) if I separate white-peace a not-co-belligerent ally-nation I'll have truce until may 1664 with them, but if I take war reparations from them the truce will last until 1659. so clearly either the formula listed in the wiki isn't right or it's a bug or there are special conditions 09:56, 2 January 2015 (CET)

Peace offer[edit source]

war goal: show superiority(expansionist finisher cb against indian nation) 2-province country, occupied both provinces, can annex. If I give occupation of 1 province to my vassal I can no longer annex it, there's only an option to annex this province by vassal.

Logically I would've expected it to have an option of annexing the 1 province left (capital) myself, while my vassal gets another province.. 09:56, 2 January 2015 (CET)

[edit source]

add info about taking money in a peace deal 13:39, 23 January 2015 (CET)

ticking warscore[edit source]

add the exact number of tick per month 09:24, 20 January 2015 (CET)

Peace term "Transfer Trade Power" halted by loser[edit source]

When the loser manages to convince another nation to transfer trade power to the loser, the loser will cease transferring trade power to the winner.

Bug? Impossible to have Party A transfer trade power to Party B who transfers trade power to Party C? — Preceding unsigned comment added by Jonwong (talk) 03:39, 11 November 2016 (CET)

Wargoal, warcost, peace term, aggressive expansion etc...[edit source]

About the general topic around wargoal and peace deal, I thought it is a bit messy right now. I was trying to do a summary for myself and saw that information are explode in many place for the same topic. Some costs are presented in the main article "casus belli", the aggressive expansion is described in "relation" page, there are redundant information not consistent to each other, the paragraphs "sue for peace" and "negotiating peace" of this article have illogical patterns etc...

I think it can be a good idea to create a dedicated and self-content article for all of these topics (Casus belli, wargoal, warcost, costs in term of prestige, diplomatic power (unjustified demands), aggressive expansion) as it is done for the topic "casus belli" itself. I'm already working on it actually and it was difficult to find the right place to put my improvement/correction.

What do you think ? --FrogCrusher (talk) 11:38, 31 January 2017 (CET)

I would suggest to use a sandbox for such an article and perhaps even ask for comments on further improvements before final deployment. Redundancies can then be easily solved by transcluding the relevant sections to where needed. This way you can test the page to your heart's content and check how to integrate all the necessary information together. ~ SolSys (talk) 19:12, 31 January 2017 (CET)
Fine! I will do it on my user page :) Keep you in touch here. --FrogCrusher (talk) 20:55, 31 January 2017 (CET)

removed sentence about warscore cost for forcing religion in the Peace terms section[edit source]

I removed the sentence "Force conversion will have the same war score cost as annexing the nation.", because that is rarely the case. With the conquest CB, the occupied wargoal will have a lower warscore cost and with the reconquest, imperialism, nationalism and several other CBs some or all provinces have a lower warscore cost. But these reductions don't apply to force religion. The warscore section already has the information that the cost is the sum of the warscore of all provinces. So I don't think that this sentence is necessary. --Grotaclas (talk) 04:58, 27 January 2021 (UTC)

Occupied and besieged provinces, and stability hit for AI refusing peace[edit source]

This formula refers to "base tax" which has been replaced by development for most purposes since way back in 1.12. "Distant overseas" also hasn't been a thing for a very long time – I suspect that rather than anything being ignored, the formula instead uses autonomy-adjusted development. The section on making peace claims you can force AI to take a stability hit by demanding provinces without taking a fort, but I believe you can't even submit such an offer now. This all needs testing. Hairy Dude (talk) 02:21, 9 April 2022 (UTC)

Cost of Enforcing Religion Through War[edit source]

I did not want to cram all the bonuses in the notes on this table, but since everything links here I decided to add the missing modifiers. It is not pretty and needs cleaning, but I believe all modifiers are now displayed when people get linked here after searching for it. --2003:E1:BF05:3700:F537:74CC:4C9A:577A 15:55, 21 February 2023 (UTC)
