This is great but it still uses the province name. It would be nice if it took the name from the location

Thanks man, this is the closest you can get to a custom nation designer or a custom ruler designer at this time. Can't believe paradox cucked us on custom rulers

can you add a way to rename the vassal ?

Wonderful. I will try this out again and see how it works.

Hahha, you're right, some more info might be helpful!

For now, let me explain: The mod adds a new Cabinet Action (Release Location Vassal) that releases a location level vassal. You use the Cabinet Action, fill all the prompts, and then you wait 1 day. Once the day is finished, it will automatically release a vassal.

I can't figure out how to use this mod. Please upload more images, a video or a guide on how to use this as there is seemingly no way to release a small vassal with this mod.

When you say Ruler, do you mean Fiefdom subject type?
I haven't used the mod yet but I would be interested in one that can release a subject as a Fiefdom and you get to choose the culture and religion on a province based level.
