How is war contribution factored?

[TheMeInTeam]

Right now, I'm not sure and I can't see anything about it on the wiki and I've done a few searches to no avail. From what I've read on forum topics, it seems like these all (might) matter:

- Battles fought: pretty good measure.
- Occupied provinces: again, important to wars. How is it weighted vs battles? Supposed the former gets more weight.
- Manpower lost: This needs to go if it exists independently from battles fought. The AI should not be rewarded for bad attrition micro, and the player should not be rewarded for taking attrition/fighting battles in a separate war.

To really use this mechanic well or critique it requires knowing how it works though. This is a gameplay rule, not AI decision logic, so it is not something that should rationally be hidden.

- Each day in battle, you get war contribution based on the power of the troops you have committed, taking losses gives more contribution. Heavily lopsided battles give less contribution.
- Each day in siege, you get war contribution based on the power of your troops in the siege, but only up to the amount needed to siege the fort (so piling 40k on a fort that needs 6k gives same contribution as 6k). Battles give more contribution than sieges.
- Each day blockading, you get a little bit of contribution.
- Contribution of subjects is given to overlord.

It's not exactly hidden on purpose, more that it's not something you can really show nicely in the interface.

Thanks for clarifying, and I'm glad I asked. It seems some of the speculation was misguided. That looks like a pretty solid set of factors. It only counts sieges against nations involved in that war, correct?

I was wondering how I got some 8 favors for joining a war for Hsenwi against some of its neighbors in SEA and then doing nothing, and was hoping it wasn't because I was sieging Uzbek. My vassal Nepal did go down there though, so maybe that's why.

How does Contribution factor into the AI peace making decisions? Does it now use Contribution instead of the players (or any other non warleader members) actual WS? Is it both? Imho it should be based solely on contribution, as battle WS all goes to the Warleader instead of the ally.

It's even nicer now to have suicidal vassal!

So if i siege a province for an ally and it stays occupied for a year. but before my ally makes peace he looses control of the province does that still count as favour gained even though it was lost before the peace was signed?

Given that Wiz says contribution is given at the time of the battle/siege, and not for holding the fort, that would seem to be the case -- it's about how many resources you invested into the war, not how successful you are.

If multiple allied armies have troops in the same siege, does every one of them get credit up to 6k? If not, whose troops are prioritized?

What if you give subsidies or a gift to your AI ally? that should give a little bit of contribution.

Is there a cap to this?

Because in my current war it just feels wrong how the contribution is shown... and my onyl guess is that Castille gets a lot of contribution from some early blockades.
I am France fighting in a war against Aragon and Portugal. My ally is Castille ( I called them in promising land)
Their contribution was to the siege of the Portuguese Capital (Fort Level 3) and some very minor battles.
I defeated the Portugues and Aragon army and took all of Aragon's land ( 3 Level 2 Forts and the level 1 capital).

So on the peace screen it says that Castille contributed 67% in this war, which in my opinion is just a bit too much (maybe more like 30-40% would feel ok)

Blockades give very little contribution.

Now wouldn't it be nice if that same formula was used to calculate army/navy tradition as well?
