Dev Diary #58: Stre(ss)tching the traits

Hello everyone!

Nice to meet you all! I recently joined the Crusader Kings III game design team and am honored to inaugurate my PDX account with this Dev Diary. Today we will cover two improvements planned for the upcoming patch: additional content and AI warfare improvements.

Trait changes

One of the many pleasures of Crusader Kings is to personify a plethora of characters. Every one of them offers a good opportunity to roleplay, thanks to the various combinations of traits they offer. The Azure patch will expand upon existing content by updating and adding some trait-specific interactions and consequences. With this update, we want to connect the stress system even closer to personality traits.

One of the notable changes is for Shy: it will no longer generate Stress when launching a Personal Scheme. Shy characters can still receive Stress via some of the scheme event options however, and they will be less efficient at performing personal schemes (it will take them longer), but they will be able to do it without ending up having a mental breakdown.

We also added a few new interactions and decisions. For instance, Forgiving characters can abandon one of their hooks to lose Stress. You can either decide to be a truly forgiving character, abandoning a hook you obtained unwittingly, or you can actively look for hooks and then choose to be merciful. We have also added new options for Diligent characters; they can dedicate themselves to improving the Development of their Capital, but doing so will generate a lot of Stress. Finally, if Impatient characters are Stressed, they can speed up the progress of their current Personal Scheme, without affecting their current Stress levels.

Some traits have also gained access to interactions that are not related to the stress system but still improve upon the expression of their personality. For instance, Arbitrary characters can now dismiss a Hook a vassal holds on them by spending a lot of Prestige and gaining Tyranny.

We would love to hear your feedback, and also suggestions for improving other traits!

AI and Warfare

There is also a number of AI improvements, mostly about how the AI moves its units while at war. Pathfinding has been revised, and AI armies should now take more optimal routes to reach their targets, whether they be close but surrounded by treacherous terrain, or far away across the sea (which was most visible during Crusades; there will be no more island hopping for Christian armies, and Vikings should also be more swift and direct in their raids). The new pathfinding logic now factors in time, attrition and threat when selecting and routing to a destination.

Getting close to the enemy is only the first step in warfare though, and the AI should behave more sensibly in other areas too. After winning crucial battles, AI armies should use their full might to more efficiently besiege enemy fortresses – you should see less mangonels and bombards chasing peasants while there is a perfectly good castle waiting to be ruined. We also adjusted the AI behaviors depending on their Casus Bellis, making sure that they not only prioritize territorial conquest but also capturing hostages when relevant. While there’s likely to be some odd behaviors in the military AI still, we believe this will be a noticeable change in the right direction.

Lastly, an important organizational change: the version number of the patch will be 1.4 instead of 1.3.X as announced previously. This is to make the scope of the patch a bit clearer. While it is still a relatively small patch, it is also larger than a hotfix or a pure bugfix patch we’ve released in the past. Some mods will need to be updated. And while we always strive to keep save games compatible, with the nature of the game you might still run into edge cases with your old saves that we did not catch.

And that’s it for today! Thanks again for your precious feedback, and please keep providing more! I hope you enjoyed it, and see you next week for more information about the Azure patch!
