It's time for the second of three dev diaries on the new expansion for Crusader Kings II; the Sword of Islam! Those who watched yesterday's live stream already know a bit of what I'll talk about today. Just like last time, I'll talk about both some unique Sword of Islam features and some free stuff that comes with patch 1.06.

THE SWORD OF ISLAM

Our intention was always that playing a Muslim should feel quite different from playing a Christian ruler. One of the major differences, of course, is the ease with which you can ensure the continuation of your line. Muslim men are allowed to marry up to four women, and bastardy does not carry the same stigma. This means that Muslim dynasties tend to be huge and sprawling; especially the powerful ones. Unfortunately, all these princelings will expect a share of your wealth, and unless you can give them enough land and responsibilities, they will grow decadent, or at least, your dynasty will be perceived as being decadent. Decadent dynasties risk being replaced by more dynamic and righteous ones, and also suffer penalties to troop morale and demesne income. To compensate for these problems, Muslims have an easier time conquering, through special Casus Bellis (more on those next dev diary.)

Polygamy

The way polygamy works is that only your first wife gives you a skill bonus, but you're allowed to marry up to four. They all give you alliances, and they can all provide you with heirs. Rulers are expected to marry a number of wives corresponding to their station, so a Sultan should have four, or he will take a monthly prestige hit, whereas an Emir is only expected to have three wives, etc. Having multiple wives means that you will produce a lot of offspring, many of them half-siblings. Ambitious mothers will tend to favour their own sons, which can lead to all kinds of nasty business through events...

Open Succession Law

Muslims have access to only one succession law: 'open', also known as 'Turkish'. The way it works is that your son with the most titles and vassals inherits. There is no "unlanded sons" Prestige penalty, but there is still pressure on you to land all of your sons, because adult men of your dynasty will accrue Decadence. In the Muslim world, brothers, especially half-brothers, dislike each other (negative opinion modifier.) This means that Muslims tend to suffer frequent succession crises.

Decadence

Decadence lies at the heart of the Sword of Islam. It's what really separates Muslims from Christians; not that Christians could not be perceived as being individually decadent, but there was not the same type of friction between clans and tribes. Thus, decadence affects the whole dynasty. Dynasties start out with 25% decadence, which has no effect one way or the other. Decadence increases by having indolent, unlanded males of your dynasty kicking about, depending on their rank and the total rank of all titles held by members of your dynasty. Dynasty members who give decadence are listed in a new list in the Religion View (well, they are immoral.) You stop them from gaining decadence primarily by giving them enough land, imprisoning them or simply killing them off. You only lose decadence when dynasty members fight in battles and sieges, or through certain events. The decadence level affects the morale damage your demesne troops take and the tax income from your demesne. At 75% decadence or more, there is a very real risk of a more dynamic tribe riding in from the wastes to depose you and your whole House (this is one serious rebellion...)

THE 1.06 PATCH

On to the 1.06 patch!

Strong and Weak Claims

There is a problem with the old claim system, in that some very remote relative can just declare war to supplant not just a perfectly legitimate ruler, but also the next five people in line to the throne. Therefore, we've reworked the system to differentiate between strong and weak claims. Strong claims work like before, but are only given to the second and third person in line to the throne when a ruler dies. Weak claims are given to children who are further down the line of succession. When a strong claimant dies (and the claim is "pressed"), it is inherited as a weak claim. Weak claims can only be pressed against women (if the claimant is male), regencies, titles currently in a succession crisis and titles that the claimant is second or third in line to inherit.

Plots

We've added and changed some things. Chiefly, we've added a plot to gain a claim on the title of a target character. Also, the murder plots have been completely reworked. You no longer get decisions that you can simply execute at various plot power levels. Instead, plotters can randomly find opportunities to strike depending on their contribution to the plot power.

Event Window improvements


We've made some changes to make event windows more appealing. You can now see the icon, with tooltips, of traits being added or removed in an event option. Also, event options that only appear if you have a high enough skill are now properly marked with a coloured border.

I believe that will do for now. Next week I'll talk about the Muslims CBs, vassal treatment, temple holdings and laws, as well as some more patch features. Until then!

Remember that between Abbasid and the Ottoman conquest of middle east, Islammic Sultanates/Caphiates often raised, had an golden age and disintigrated within 150-200 years, and for the last some 300 years the Abbassid's was more often than not, only Titular heads of state, with the true power laying with the strongest Amir in the area (be it Buyid, Seljuq or whatever)
 
Four wifes? I believe fertility is going to have to be turned down... :p

Well, it already is turned down in the vanilla game (to about half of what it should be). We could use some "death in childbirth" events though (even if with a rather low chance - it was something like 1% to 2% per birth during the time period for young mothers, a bit more for elder ones).
 
Suggestion: give Muslims some 'cultural' type buildings to construct in their provinces, which will give a reduction to decadence. Either one-off or ongoing, whichever fits better. That would represent a ruler who established a strong reputation by being a patron of the arts, building mosques and lawcourts, and encouraging trade. It would allow for a more peaceful playstyle, for those so inclined.

Good idea.
 
Fantastic!
 
Great DD! Some questions:

1) How does divorce work for Muslims in the expansion?
2) Has anything changed with usurping for Muslims in regard to laws carrying over? If I usurp a kingdom with Agnatic-Cognatic Primogeniture will that allow me to break out of the Agnatic-Open Succession lock for Muslims?
3) Is it just me or does it seem really easy to abuse Open Succession? Give my favourite son a duchy and give all of the other baronies. Done. Let's see them go into rebellion now!

And a question from last week: how does the dynasty name in your country tag thing work with multiple kingdoms held by the same dynasty? If there are two Fatimid Sultans, do they both appear as Fatimid Sultanate on the map?

A really good point with point 3. Technically, all you have to do is give your "flunky" sons a barony here or there and you can always pick the youngest son with the best stats. What's more, if you don't want to deal with sons all over the place, marry a first wife that is brilliant, then marry 3, 69 year old hags. If your first wife isn't producing very good heirs then, well, no big deal. One of your older wives will disintegrate from old age sooner than later and you can marry a nubile young genius. Rinse and repeat for an unending dynasty of competent leaders.

Well I've heard it all now, I really have. ;)

Death in childbirth would be nice, but having the option of rounding up and slaughtering your relatives wholesale would be a pleasant surprise, too. Oh, the things that CK2 makes us say.
