Diplomacy cost for vassal annexation

[lougarou]

Hello,

I have been away from EU4 since at least 1.4. At the time, there was no cost for annexation of a vassal, save waiting. Now it looks like there is a price in DIP points. Anybody knows since when, and how much?

Since 1.6, although the rules keep changing. It now costs 10 DIP per BT, and the DIP ticks at a variable rate. +1 base per month, another +1 for same culture, +1 for same religion, and +/- X where X is your diplo rep. Furthermore, anything that increases coring costs now also increases dip annexation costs by the same amount.

The price has existed for a few patches, introduced in either 1.6 or 1.7. It is currently 10 Diplo points per base tax. When you start to diplo-annex, you spend a certain amount of points each month until you've spent the full base tax worth, at which point the country is annexed. Your Diplomatic Reputation modifies the number of points you can spend per month, and there are some ideas and traditions that can lower the total number of points needed for annexation as well.

To go with this new change, actually annexing a vassal no longer penalizes your Legitimacy or Republican Tradition. Instead, you get a -3 Diplomatic Reputation malus that will last for ten years, making further vassal annexations slower during that span.

Which can be worked around by annexing multiple vassals timed to end simultaneously.
I am too lazy to do that though. I just buff my diplomatic reputation to 5 or 6, and since the -3 penalty does not stack, I can afford to ignore it...
