Paradox Development Studios is crafting their latest mini-expansion for Europa Universalis IV. It's called the Art of War and significantly alters the main game. This latest dev diary gets all diplomatic.
We'll now be able to declare war on a nation in support of rebels, or even our vassal's casus bellis, and losers in a conflict can now be made to pay war reparations throughout the truce.
The studio is certainly spicing things up with this new DLC. The Catholic Church is another area of focus, with a big overhaul on the cardinals - they're now tied to provinces.
No longer will it be a maddening (if now somewhat automated) spending of influence to try and sweep your dominance through the Curia. Instead major provinces will have cardinals permanently based there, giving their owners control over them, unless the province is no longer catholic of course.
Papal influence will still have a role to play, with each Pope at the start of their reign deciding who the new Curia controller is. It's here you'll still spend those points to win favour and stand a chance of securing the support of Rome. These same influence points can also be spent to boost our legitimacy.
There are also big changes in Indochina and Indonesia with territory maps being redrawn to better reflect the area at the time. Check out the latest Art of War - Dev Diary 5 - Diplomacy, Catholics and Southeast Asia & Indonedia.
