Crusader Kings III Patch 1.17.0.1 Notes – September 10, 2025
- Fixed the issue with always getting the Oathbreaker event, regardless of if you completed the oath or not
- The buildings needed for the three “build special oath buildings” oaths have been changed from tier 3 to tier 2
- The special oath buildings have had their costs and modifiers reduced across the board
- The special oath buildings have had some of their triggers simplified, so they need fewer of their requirements than they used to
- These oaths have also had the time you can do them increased from 10 years to 20 years
- Specifically for the spiritual one, switched the requirements from tier 3 to 2, and vice versa
- The Alliance oath has been changed from 5 alliances needed to 3
- Building Oath (the generic one) has been reduced from 10 buildings to 8, and the time available to do it has been increased (from 15 years to 20)
- Legendary Hunt has been changed from 3 to 1, and has had the time available increased (from 20 years to 40)
- Fixed the Prepare Heir oath decision, so it checks for the proper scope in its requirements, and also removed the gold cost
- Added two new modifiers for the AI, so if they choose a warlike oath, they will have an increased war chance, and similarly, if they have the peace oath, they will have a peace oath, which will decrease their war chance
- Removed health bonuses and maluses from Prepare the Heir rewards
- Added extra checks for the AI so they will try to take oaths that make sense
- Fixed the End the Struggle oath, so it correctly tells you which struggle area it is targeting, and massively increased the time it is available to you (from 20 years to 50)
- Increased the time available to do the Repent Oath from 10 years to 20 years
- Fixed Anointment Doctrines and Anointment activity type being available to faiths with Temporal Head of Faith (these are for Spiritual HoF faiths only); temporal HoF faiths have guaranteed access to regular coronation instead
- Fixed duplication bugs and self-crowning malus caused by temporal HoF being Coronation host
- Blocked the building oaths for Nomads and Tribals
