How is the colonial/coring range determined exactly?
Hello. I've decided to try a Big blue blob achievement so I declared on Denmark and took some land from Norway and Sweden and now I'm having troubles coring it.
I own Romsdal, Trondelag, halogaland and Finnmark. As you can see in the screenshot Romsdal is cored and in a state:

But the distance to the next province not adjacent to the cored province is still too large to core it:
http://steamcommunity.com/sharedfiles/filedetails/?id=914671067

I've read that moving your capital as far North as possible helps but I haven't found any mention of a connection between colonial/coring range and capital position on the wiki. So should I move my capital or not and are the colonial and coring range the same thing or not after all?

Colonial range is based on a cored province and it does not matter where your captial is. A cored province could be a self sustained colony like Cape Verde which allows Portugal to jump to the Americas or West Africa early game.

Just wait until you increase your colonial range and then you should be able to core the other provinces in Norway. Moving your captial there will not change your colonial range.

To increase range:
Eploration Group - third idea chosen increases your colonial range
Advisor - gives 20% bonus
Diplo Tech 7 - gives another 115 colonial range

hopes this helps

So the problem in my case is just that Scandinavia is large an provinces are far from one another?

Well it helps to now that moving capital does not help... I don't think it's possible to increase the range in the time required for the achievement though...

Yeah seems like thatis the issue the range between provinces. It looks like you may only need the advisor giving the colonial range bonus. The distance is 106 right? and you have a 100 colonial range at game start.

I have never tried that achievement is there a time frame it needs to be completed in or can you conquer those provinces later in the game after your tech increased?

Big Blue Blob requires that you play as France and have 100 cores in Europe before 1500.

It is pretty tough. After playing the campaign for 55 years I was late by 10 months... :steamsad: Oh well, I guess now it's time for less demanding French achievements.

Not 100% true the region your capital is in have some effect. Many player going for the achievement did move capital to Scandinavia as it made coring in the north easier.

hmm I didn't see a boost to colonial range by moving a capital in the wiki. I may be wrong so I am intersted to see how ZeratulR can be helped with this achievement.

Well, I got the achievement on the third try (the Southern route turned out to be so much easier than Scandinavia...) but I must say that I still don't understand how the coring range works exactly. For example this screenshot:

Somehow I was able to core Styrie without coring Carinthie before that, even though Styrie is landlocked and neither me nor my vassals border it. Does it have something to do with my capital in Paris being close? I don't know...

From the wiki:
If a country has a core in province A, then it can core any province that has a "land bridge" to A.

In this case, A is that province south of Carinthie.

What is a "land bridge" exactly?

It's not explained any further in the wiki either, but I'd say it just means that the province you want to core has to be connected by land to a province you already cored. So if you continue making a blue line through Europe, you should be able to core everything on your way as long as it's connected to that province.

I agree that the game does weird stuff with respect to coring range.

However, if you look at the colony map, you can frequently get insight into why a province cannot be cored.

Unless something changed, a "Land Bridge" can also pass through a province occupied during war. So, if you go to war with Norway there and occupy a province you might be able to start the core during the war - unless of course Norway has a core in that province you want to core.

Well, there are special rules for coring within the HRE. I thought it was something like if your capital is in the HRE then you can core any HRE province no matter the distance. Maybe it only applies to the Emperor but I don't know.
