Yet another Naples question - How do I join the HRE? Do I need to move my capital to a province in the HRE and buddy-buddy with Austria or what?

You can't change your capital to a province that is already in the HRE.

Instead, your existing capital needs to border HRE land, then you click Add to HRE on that capital. So, move your capital first (if necessary to get it bordering), then add it to the HRE.

You can only add your capital if the total sum of your per-province base tax is 50 or less. So look at all your provinces, and add up their raw Base Tax number (as shown in the province interface). This is not modified by buildings, tech, anything, it's the basic Base Tax number.

You then need relations with the emperor of 100 + (2 * SumOfProvinceBaseTax). So if you were an OPM with a Base Tax 1 province, you'd need relations of 102. If you have the maximum sum of 50 Base Tax, you need 200 relations.

If you have more than a total of 50 Base Tax, then the add to HRE button will be greyed out with a message "We are too big, the current Emperor would never allow it."
 
I was trying to diplo-vassalise Denmark (2 provinces left, one with base tax 7, the other with base tax 3) as Sweden (temples in all provinces, constables in several high-tax ones).

The game told me it was impossible because of "Danish base tax compared to Swedish".

Does it mean mine is too high or too low? Any advice would be appreciated.

You must have a higher Base tax, use this formula:

60*(your base tax)/(target's base tax)^2 - 90

Just tested it and yes, Naples can join HRE. It has to be adjacent to HRE and opinion of emperor should be +194.
But if you manage to conquer a single HRE province, you won't be able to move your capital there and become part of empire.

It says 'as well', implying the player could already be replaced as warleader in an offensive war. I don't see a Patch Note changing that, but I guess that means that yes, the player can always be replaced as WL.
I think the 'as well' means 'humans as well as the AI'.

Thank you. I assume you can find those in the ledger somewhere?

It isn't base tax, it's tax base which is somewhat different. You can find your tax base value on the economy page...

To calculate the target's tax base use the following:

total base tax+(# of temples)+(5*number of stock exchanges)+2

So, using your case of 2pm Denmark with base tax of 7+3 their tax base is somewhere between 12 and 24 depending on what buildings exist in the two provinces. If both have temples (fairly likely) then the value will be 14. In that case you would get the following for the modifier:

your tax base*(60/196)-90, figure out what your target modifier is and you can figure out what your tax base needs to be to get there For a -30 you would need a tax base of 196

Note that your tax base is calculated the same way but also includes half the tax base of any vassals you might have. So, to further our example, let us assume that Denmark does indeed have two temples, giving the a tax base of 14 and that you raise your tax base to 196 and succeed in vassalizing them with a -30 modifier. Your tax base would immediately increase from 196 to 203 thus slightly improving your ability to diplomatically vassalize other nations.

There's something else about vassals as well, which I haven't quite figured out yet, and not properly tested.

Specifically, my DipVassalise Base Tax modifier noticeably worsens whenever I DipAnnex an existing vassal.

This is the opposite of what would be expected if the vassal counts only "half". Of course it could be that when you DipAnnex you lose some buildings? But in the cases I'm currently seeing, this would only apply to Temples, not Stock Exchanges, as neither I nor my vassals can build SEs yet.

The example I'm thinking of most recently is when my modifier got worse to the tune of 2 or 3 when I DipAnnexed a 2PM, Trier.

Do you lose Temples when you DipAnnex a vassal? Even if so, it's still weird I'm seeing such a noticeable worsening in that modifier based just on losing, at most in my recent example, two temples - which according to formula, should count for a tiny fraction of a difference given it's halved anyway for a vassal, then compared to a squared target amount.

Or it might be related to the static +2 that you note in your formula - maybe this is added statically for each vassal, and added added on to the whole total calculation after comparison against the targets, such that it's not being compared against a squared target figure.

I will test more on this in due course, but in the meantime any further info you have would be appreciated!

In addition to any lost buildings, you also lose the free +2 for their capital so annexing fairly poor vassals can result in a very slight loss of tax base. It may well also be the case that the instant re-calculation is flawed and you just lose the entire value of the vassal from the previous monthly update until it recalculates without gaining the value of your new provinces.
 
My vassal is in coalition against me. Is that a bug or - for some reason - WAD?

Definitely a bug. But I have had that happen as well, but they switched after a while. Also, if you declare war on another coalition member, your vassal should be on your side, even though it said oppositely.

It isn't exactly a bug. Nations are only allowed to leave coalitions under certain conditions. Your vassal will officially leave the coalition as soon as they are able to do so and, as you mention, will not actually join the coalition in fighting you in the interim. It makes perfect sense to me that they would retain their declared animosity should you lose control of them before they are free to leave the coalition.

wauw. And I thought HOI3's supply system was complex :rofl:
That makes it perfectly clear. Thank you, good sir.
 
1. I'm playing my first game as Austria and so far it feels like herding cats with all of this pissant nations warring each other within the HRE. The thing is is that I'm allied to some HRE electors and sometimes they call me to war when they DOW on another HRE member but what should I do? I don't want these guys fighting each other and I don't want to help one HRE nation conquer another, or do I? So far I've been turning down alliance calls for intra-HRE warring.


2. I noticed several posts above talking about vassalization and tax base - I'm buddy-buddy with Ferrara but they turn down my offers of vassalization because of base tax differences. I have temples and constables in all of my provinces but they still won't accept vassalization. Should they remain as a small HRE member or should I conquer them?

3. I inherited Burgundy but to change the cultures of all of those provinces to Austrian is enormously expensive! Should I release Burgundy and some of the nations she annexed as vassals instead? If I do that then I go way over my diplomacy limit. What should I do here?
 
What else can i do to get the 190 Hungary opinion?

The obvious thing to do is make Austria, Savoy, or Tuscany your rival and wait for the Enemy Of My Enemy bonus to build up.
 
What counts as "coastal" province? Is an island considered a coastal province? The province in the picture below is within my colonial range and it looks like it's on the coast of Africa but I can't colonize it.
