Witcher Kings 0.8.1

News 15 comments


Hi folks,

Though Witcher Kings 0.8.0 was quite stable (no random CTDs), there were a few nasty game-breaking bugs (witchers and sorcerers getting pruned, random education traits, bedridden immortals with Reaper's Due) and lack of Conclave support. This is the reason for patch 0.8.1, which is a save-compatible bugfix and balancing minor update.

Automatic .exe installer (Windows)

Witcher Kings 0.8.1 - Windows Installer

or manual .zip install (Windows/Mac/Linux)

Witcher Kings 0.8.1 - Manual Install

Compatible with: 2.7.2
Checksum: 2.7.2 (PETO)
It is save-compatible with Witcher Kings 0.8.0.

For more information on the mod, checkout the Witcher Kings wiki page.

In parallel we've started working on our next major update, called the "W3 update", so stay tune for more in the coming weeks ! ;)

Let's Play series

Before describing changes, I'd like to start by thanking AlpaxLP for his great Let's play King Foltest of Temeria series on Witcher Kings 0.8.0 !

His video series helped to find some bugs, balance and usability issues. It's very instructive to see someone else playing ! :)

Conclave education

Conclave DLC is now officially supported !

The mod has 4 generalist education traits that give bonus to all 5 attributes, but with smaller values than the specialized trait at the same tier.
In order to have these education traits as a possible outcome with Conclave education focus, a new "polymath" education focus has been added, and the UI tweaked to display the 6th focus:


The first tier trait, "uneducated buffoon" trait is now a probable outcome of not having an education focus (or utterly failing when having the polymath focus !).


The mod also adds 4 personality traits: tolerant, racist, gambler and reasonable.
These traits are now integrated with Conclave childhood focus:

  • Affectionate can lead to tolerant
  • Haughty can lead to racist
  • Playful can lead to gambler
  • Conscientious can lead to reasonable


In addition the adolescence age has been decreased from 12 to 11 and childhood age from 6 to 5, to preserve Conclave education balance (attribute gain, events MTTH, ...), as adulthood age is 15.

Dynamic flags for Nilfgaardian kingdom vassals

This idea was inspired by the e_iron_throne title's flag in the AGOT mod, which changes based on the ruling dynasty.
Kingdoms have a different flag when vassals of Nilfgaard (the Nilfgaard sun, typically added above or next to the kingdom's original flag), but revert back to their default, "de jure" flag while independent:


Witchers and sorcerers pruning

Due to a vanilla engine behavior, characters present at a court that experiences an inheritance of title have a chance of dying of "natural death", bypassing the normal rules of pruning (aka "disappearing without trace"). With the workaround, immortal (landless) characters are now really immortal !
But what about long-lived races ? Though they have an immortal trait, as they are also randomly generated by the game, they also need to be pruned, otherwise courts would bloat and game performances would slow down !
Now that this issue is fixed, the number of child with hidden magic talent had to be toned down a bit. For witchers there's a spawning event if there's 5 or below, because they may die out fighting monsters occasionally.
I've run several observer games (100 years in-game) to check and tweak the pruning/generation.

Wrong checksum warning

The Windows automatic installer has helped reduced drastically support and false-positive bug reports due to bad mod installations.
However it was still happening from time to time from players with manual install, or when CK2 updates and the mod is not compatible with that version yet.

So there's now a startup event (on new game start and when loading a save), that will warn you if you don't have the expected checksum(s), with some clues on what to do in such case:


In case you're using a compatible mod that modifies the checksum, you can disable this warning via the game rules.

Helping with the mod

The potential of the mod is huge, and the team is very small, while there's still a lot of ideas to be implemented !

You can help by:

  • reporting bugs
  • giving suggestions, ideas and feedback (balance, fun, ...)
  • doing some modding (research, graphics, scripting, ...). If you're interested browse the opened issues on the Github repository and contact me.

Known bugs

  • Only human sorcerers are generated
  • AoK narrative events don't fire after resigning (need to restart the game)
  • Filavandrel gets a child portrait

Update for 2.8????

it;s gonna take another eternity for them to release a small patch for this mod. They are barely doing anything, mod is still very raw with very little to do in it.Might as well look elsewhere.

Hi guys,
Even though I rolled back to 2.7.2 and have version 0.8.1 as soon as i finish selecting the rules and press start, the game immediatly crashes. Can you help me please?

Reply Good karma Bad karma+1 vote

Hi jonny888,

Double check you don't have any other mod active, and that Jade Dragon DLC is disabled. Other than that, also verify that the rollback to 2.7.2 was successful / verify Steam installation files.

Any indications on when the next version will come out? Even just a compatibility update to JD would be tip-top! Asking just because I REALLY like this mod and can't wait to play with the increase in perfomance of JD.

Can anyone help? Playing multiplayer with a friend and game crashes to desktop every time I 'Offer Peace' > 'Enforce Demands'. :(

What is the Casus Belli of the war ?

Fabricated claims, playing as Duke Cedig (Aen Seidhe). White peace and Surrender options both work as normal.
