December 2

Monks and Mystics announced!

Let’s Talk About Sects. Monks and Mystics Coming to CK2
Newest Expansion to Crusader Kings Increases Your Faith

STOCKHOLM – 2 December 2016 – The bells of the abbey summon monks to prayer while, a continent away, the faithful are summoned by a muezzin’s call. Religious practice imposes a schedule on the chaos of medieval life, and the routine adds harmony to a divided realm.

Routine and harmony. We can’t have that, can we?


Monks and Mystics is the latest expansion to Crusader Kings II, the hit medieval grand strategy role-playing game from Paradox Development Studio. In Monks and Mystics, the religious aspect of the game is further explored with new mechanics and character associations that can tie a faith closer together or render it asunder.

The major feature of Monks and Mystics is the addition of Societies – secret and otherwise. Characters can join monastic orders, secret cults and Gnostic heresies. As the society gains members, it gains power and prestige for its leaders. Societies open new actions for characters and can lead to new event paths.

Monks and Mystics includes:
Monastic Orders: With lay offices available to non-clerical characters, monastic orders will increase your character’s piety - but they have expectations.
Cults: Gnostic heresies may flourish and its is rumored that the worship of Satan continues in the darkened fringes of the world
Climb the Ranks: Characters work their way up the ladder of Societies, unlocking new abilities and triggering new event chains
Hunt for Heretics: Send your chaplain out to find secret societies that undermine the holy church and your realm. But what if the hunter is guilty himself?
Other New Councillor Actions: Your councillors have a fourth action that will make them more powerful and integral to sound rulership
And much more: Assassins, archaeological expeditions, holy relics, great treasures and more

Crusader Kings II: Monks and Mystics is coming soon to major digital retailers, including the Paradox Store.

Intriguing quality of life changes

Good afternoon. I’m Magne Skjæran, and you might remember me from my modding and optimization dev diary at the end of summer. My last day at Paradox was a few days after that, but since I had a great time working there this summer, I returned to the CK2 team about a month ago to work on the game part-time.
Today I will be covering a topic that’s been briefly mentioned earlier in the Easing Executions dev diary: quality of life changes in regards to the intrigue screen and plotting.

While the image shown in that dev diary was a mockup, the planned changes have now been implemented. However, the actual art isn’t done yet, so most images in this dev diary are touched up based on mockups rather than showing my programmer art. There is after all a reason I work as a programmer rather than an artist.

So let’s go through all the changes we’ve made to the Intrigue screen in detail:

I’ve numbered the changed aspects.

First, at #1, we’ve got the new decisions menu. It now shows 6 decisions at once rather than the old 4, making it easier to find what you’re looking for.

At #2, you can see that each decision now has a button allowing you to mark it as important or not important, thus allowing you to control which decisions you get alerts for. Marking a decision as important will change the background to gold, enable alerts, and move it to the top of the list. The last bit only happens once you exit and return to the decisions screen, since decisions jumping around when you click on them would be rather annoying.

#3 is a button allowing you to reset the priority settings to default.
What decisions are important is saved across campaigns, so you won’t have to mark decisions as important or not important every single game.

Further, at #4, we have a new tab: My Plots. This mostly just moves the plot functionality out of the way to give more space to the decisions list, but it does have one new addition: you can now clearly see who the target of each backed plot is, shown at #5.

Next, let’s go to the Prisoners screen:

At #1, 2, and 3 you can see the new prisoner mass actions. These allow you to release, ransom, or execute all prisoners currently shown on the screen, except those that have been marked as locked using the button you see at #4.

Further, prisoners can now be filtered by the eight different criteria you see at and below #6. This can then of course be reset back to being unfiltered using the button at #5.
A minor change is that this tab now fits 6 prisoners at once rather than 5.

When using the mass actions you’ll be asked to confirm and told about the ramifications of your actions:

This ensures you’re never caught unawares by tyranny or similar.

Next up, Known Plots:

Here there’s two new additions. At #1, we’ve got a new button that lets you ask the plotter to end their plot, saving you a few clicks.

At #2 we’ve got a new feature: if you know about a plot and you’re in the group of people that’s possible to invite, you can ask to join. The AI will always accept this, while if you’re playing multiplayer the other player can refuse if they want to.

The “auto stop plots” button has also been moved to only show up within this tab.
As to the Threats tab there’s nothing new there except for six threats being shown at once rather than five.

That’s it for the Intrigue screen, but we still have a couple of tidbits related to plotting left.

When invited to a plot you’ll now be able to see who the target is, saving you from having to use the character or title finder in order to figure it out.

Finally, when a plotter tries and fails to kill your spymaster due to them discovering their plot, you now have the option to keep the plot a secret, which is ideal for cases where you would rather join the plot than expose it.

That sums up all the changes we’ve made to make the intrigue aspects of the game simpler to interact with, and providing you the information you need to make decisions. Hopefully you’ve found this dev diary as intriguing to read as it was to write!

“...playing is winning, and there’s something quite satisfying about leading your house to power and glory through whatever means you can, for as long as you can.”
9,5/10 – Strategy Informer

“In short, Crusader Kings II is a majestic feudal sandbox, the greatest generator of hilarious medieval soap opera ever created and Paradox Interactive’s best title to date.”
90/100 – IncGamers

“It's perfectly possible to have made a few too many enemies, anger the Pope and find most of Europe out for your blood. That's really what makes the game so damn fun.”
9/10 – Destructoid

About This Game

The Dark Ages might be drawing to a close, but Europe is still in turmoil. Petty lords vie against beleaguered kings who struggle to assert control over their fragmented realms. The Pope calls for a Crusade to protect the Christians in the Holy Land even as he refuses to relinquish control over the investiture of bishops - and their riches. Now is the time for greatness. Expand your demesne and secure the future of your dynasty. Fill your coffers, appoint vassals, root out traitors and heretics, introduce laws and interact with hundreds of nobles, each with their own agenda.
A good lord will always need friends to support him. But beware, as loyal vassals can quickly turn to bitter rivals, and some might not be as reliable as they seem... Stand ready, and increase your prestige until the world whispers your name in awe. Do you have what it takes to become a Crusader King?
Crusader Kings II explores one of the defining periods in world history in an experience crafted by the masters of Grand Strategy. Medieval Europe is brought to life in this epic game of knights, schemes, and thrones...
