Hello again folks! Stay a while, and listen. The highlights of today's third and last Sword of Islam developer diary are Muslim Casus Bellis, revised combat mechanics and cultural buildings. You know the drill by now; 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 direction with the Sword of Islam expansion is that Muslims should have an easier time expanding, but have an additional layer of internal strife in the form of the Open Succession Law and the Decadence system.

Muslim Casus Bellis

Muslim rulers have three new options for conquest:
  • They can declare Holy Wars on anyone not of their own exact brand of Islam
  • They can use a form of the Invasion CB for the cost of 500 Piety
  • They can conquer any province bordering one of their own for 50 Piety (vassalizing the current count if possible)

Pious Muslim rulers can thus easily expand, although they lose 2 Piety per month while attacking a brother of the faith (same exact religion.) The councillor job to fabricate a claim is thus less useful for Muslims, but can still be handy versus islands or juicy coastal counties.

Revokation of Duchies

Duchies (emirates) are not considered to be intrinsically hereditary, so Muslims are allowed to revoke duchy titles at no opinion penalty from other vassals. This is also a good way of properly landing your sons to avoid gaining Decadence. (Incidentally, the Byzantine Empire is now allowed to do the same thing, though it does not have the Decadence mechanics.)

Dynastic Imprisonment and Execution

Another Muslim exception to the normal rules is that they are allowed to freely imprison and execute men of their own dynasty, except for their own sons. Brothers and uncles are the usual targets for these Decadence reducing purges...

Temple Holdings

In the Muslim world, there is no proper equivalent to Bishoprics, so Temple Holdings are treated exactly like Castles, except for their different set of buildings. You gain Piety for having a Temple Holding in your demesne, but they are slightly poorer and provide smaller levies than their Catholic equivalents (in order to balance them against the investiture mechanics.)

Passing Laws

Muslims do not need to bother with a voting process when passing laws; they just spend an amount of Piety. However, there is still a cooldown and Crown Laws can only be changed once per ruler. The vassals will also still get upset in the same way as Christians.

Jizya Tax

To represent the Jizya tax (a special tax that should, according to Sharia law, be levied on infidels), Muslims gain a 25% tax bonus from infidel counties and a 10% tax penalty in Muslim counties. This creates an interesting dynamic where it's not always obvious that you would want to convert an infidel province to Islam. However, there is a special event where this happens anyway, even if you don't send in your Court Imam to convert the populace.

SoI_Jizya.jpg

That's pretty much it for the Sword of Islam expansion, although I'm sure to have forgotten about many minor little changes and tweaks.

THE 1.06 PATCH

Alright, so here are a few more freebies coming your way soon with the 1.06 patch...

Expanded Combat Tactics

We have added a bunch of more (and more decisive) combat tactics, to make combat less predictable and to tie in with the new Commander traits...

Commander Traits

We have added a special type of trait called Commander traits. These are only available to characters with a Martial education, and give more specific bonuses to the character's ability to lead various troop types, and the choice of combat tactics. Characters gain one or two Commander traits when they finish their education. The effects of the Commander traits directly scale with the Martial skill of the character.

More Culture Specific Buildings

One thing that many people have requested is a broader range of culture specific buildings, and who are we to argue? We have added loads of these to give more variety and flavor.

Destruction of Titles

You are now allowed to destroy ducal tier titles and above, at a hefty Prestige cost. This will greatly upset (-50 opinion) all vassals who are de jure part of the destroyed title. You cannot destroy your current primary title.

AI Improvements

Apart from some minor improvements, the AI is now better at jumping on rulers who are already embroiled in dangerous wars (though it's still not excessively aggressive about this.) I've also spent a bit of time on attrition avoidance for AI armies, and the AI will now assault besieged holdings when appropriate.

That's it for dev diaries for now. Next week, we'll post a short AAR by a member of the dev team!

On which criteria AI will do those revokations ?
I'm not sure as a duke player I will love that much if it is too random/systematic.

Excellent features mostly. Some are moderate, but none are bad or useless IMHO.

I believe you talked about weakening the Byzantines. The ducal revokation, should boost them I suppose, how will you weaken them then?

Could we get some examples of commander traits? How huge a difference will a skilled commander make? As it now, the five more archers wins the battle mostly, will it be possible to win battles where you're seriously outnumbered, but have some superb commander in charge? Like Agincourt?

Doomdark, a couple of questions if I may:

~ Have you moved over to the culture of the province script (like in Syren's mod) for cultural buildings or will they still be destroyed if a foreign-culture ruler takes over?

~ Can you give us a couple of examples of new cultural buildings? :D

as far as i remember from the stream about SoI is that Seljuk is boosted to compesate so they're a worthy opponent having a reasonably good chance of winning, sans human interruption (and is warring for all of Kingdom of Armenia now), so the question is if ERE truely have become more powerfull

well... i'm guessing it'll be balance checked and if they're still growing to strong i'd guess they could remove some preestablished holdings

They have fewer Holdings. Mainly the Seljuks are more powerful, though, and the Caliphs are likely to call Jihad on the ERE. However, the ERE is still too powerful and we are looking into additional ways of nerfing them.

I've been thinking about the power of the ERE and the HRE, as well as some of my created Empires. It seems to me that the central issue is that as an Empire gets bigger it gets more stable, since if 75% of the realm tries to declare independence you can just crush them one at a time, while in this period larger realms were less stable not more. Maybe if there was a "size of the realm" modifier for chance to declare war, like how "distance from the capital" works now it would weaken the bigger realms.

Have you increased piety gain for muslims? 50 piety for 1 province seems quite steep, not to mention that fighting a war for one province is so slow, would be better for duchy claims.


Also how are Jihads determined?

How does a Muslim ruler's relation to the caliph work? Is it the same as any vassal to a lord, the caliphs had an odd brand of secular and religious power so that it wouldn't have necessarily made sense for a leader to declare independence from them.
