Target Truces and Alliances Matter

I found it kind of weird that declaring war for someone’s titles was inconsequential for them if they aren’t independent, so I made a mod for it.

Like is says above. Say you have an alliance or truce with the Duke of Burgundy, a vassal of the King of France, but you also manage to get your hands on a claim for his title…Should you decide to use it in war, in vanilla CK3 the Duke is just…fine with that. Because see, TeCnIcAlLy, you’re not declaring war on the Duke, you’re declaring war on the King of France. So all alliances and truces with the Duke remain intact.

I thought this was silly, so here we are.

This mod applies opinion penalties to the holders of all a war’s target titles – this is what you’re likely to notice most. In addition, though, if you happen to have an alliance or truce it will apply the prestige and modifier penalties, and in case of alliance it will be broken.

Keep in mind since the game is already rather punishing when it comes to breaking truces/alliances, under the right circumstances (for example if you have a truce with both the targeted Vassal and their Liege), this mod can be very punishing. It may obliterate your prestige levels. :p

I haven’t looked into how likely the AI is to break an alliance or truce, and what influences that, so I haven’t made the AI any more or less likely to avoid these penalties.

This mod also does nothing in relation to the AI joining the war to defend their titles or not, for that I’d personally recommend Degreeno’s great Vassals to Arms mod to go along with it. 🙂

This mod is pretty small, only one file is changed:

Any mod that touches it will be incompatible. I am happy to make patches, as long as you let me know what mods are breaking. :p

One potential unexpected type of conflict: music mods. 00_war_effects.txt handles some music cues for war. If you have mods for a different soundtrack and find the wrong music triggering when you declare war, feel free to let me know and I’ll check to see if it’s because of this. ^^
