Welcome all to another fine Tuesday and its accompanying EU4 Dev Diary. In last week's diary we mentioned that we would take a look at changes to Islam in the upcoming expansion which will be released alongside update 1.23. As we have made clear, we're giving a lot of love to the Muslim world in 1.23 and as such let's look at changes we've made to Islam and Piety.

We'll start with looking at the Piety bar. As a mechanic, it has remained fairly untouched for EU4's existence. Few would doubt that the Piety bonuses are strong, but they can't be called the most engaging of the game's content. In 1.23, we've visually spruced up the Piety bar, introducing terms for both ends of the spectrum, with low Piety being called Mysticism and high piety being depicted as devotion towards Legalism. Additionally, Piety events have been rewritten to reflect different the types of piety (Mystic vs Legalistic) rather than trying to measure "how pious" a ruler was. We have also taken this opportunity to weed out some of the older events that were not up to our current standards, with book burning no longer being a Pious action.

Additionally, for expansion owners your passive Piety bonus can be passed up in favour of one-off effects depending on your Pious leanings. At -75 piety or lower, you can call on Religious Followers to bolster your manpower, gaining 2 years' of manpower growth. At 75 or greater Piety, you are able to Enforce Faithful Adherence for an immediate loss of 2 corruption. These actions will push your piety back towards the centre by 50, so consider carefully if the one-time action is worth foregoing the Pious effect you have built up.

Additionally, each Islamic nation will follow one Muslim School of Law. The School that your nation adheres to is predetermined and cannot be changed, or for new nations/converts, chosen at your spawning/conversion. Each School grants its own bonus and has a relationship with each other school, ranging between Respect, Ambivalent and Hate. While Ambivalence grants no particular effect, nations from Schools with a mutual respect or hatered will find relations and diplomatic acceptance strengthened or shakier respectively. The relationships between schools are harmed by large scale and prolonged wars between larger nations of those schools, and conversely can be improved by longstanding, trusting alliances between them.

Schools and their bonuses are as follows:

religious_schools = {
#Sunnis
hanafi_school = {
technology_cost = -0.05
}
hanbali_school = {
ae_impact = -0.1
}
maliki_school = {
development_cost = -0.1
}
shafii_school = {
merchants = 1
}
#Shias
ismaili_school = {
horde_unity = 1
legitimacy = 1
republican_tradition = 0.5
devotion = 1
}
jafari_school = {
shock_damage = 0.1
}
zaidi_school = {
shock_damage_received = -0.1
}
}

So while your own School is set in stone, we allow Islamic nations to Invite Scholars from other Schools. Assuming an alliance and high relations with another nation, you will be able to spend 50 Admin points to invite a Scholar who will give you an extra effect in addition to your own School's for 20 years.

Inviting a scholar from an opposing faith's School (Such as a Sunni nation trying to invite a Zaidi Scholar) will require low piety, although the Ibadis are exempt from this.

Additionally, as I like to do, let's have a look at Another region of the world and how trade goods have changed. In fact, let's just grab all of western/Central Europe!

With Piety and Muslim Schools covered today, we shall spend the next week sheepishly looking at two nations in particular who had a profound effect on the Middle East in the 15th Century.

Glass seems a bit common there? its almost as common as salt.

Dont worry, not all provinces are equal. Venice accounts for more glass than most of those together thanks to the Murano goods produced modifier...

Also there are 24 provinces producing salt in the continenat of europe but only 13 producing glass. There's only a handful of provinces outside of Europe producing glass at start making it a very rare tradegood.

Over a single gem province we have no idea how developed? I can't say I remember Köningsbergs being such a big deal in history. Meanwhile Gotland is supposed to be a big deal but never really is. It could use a more valuable trade good than wool or a centre of trade.

Gotland was not a big deal in this era, you're likely thinking of an earlier period. At start it is notable as the base for the deposed Erik who used it as a pirate base and that is also how it would later be used by the Danish navy. Commercially Gotland did not do well anymore at the start of our game (and had been declining for over a 100 year already) and it only got further worse over time.
To be completely honest it could be argued that the current starting development overvalues it as it is.

The Amber export in the Teutonic Order on the other hand was one of the bigger backbones of their economy (though it decreased in value after the reformation).

So the Ibadi faith doesn't have any religious schools?

Ibadi nations are more flexible, with access to both Sunni and Shiia Schools. In 1444, Mzab follows the Maliki School, Oman the Hanbali and Pate the Shafi'i. Newly created/defected/converted Ibadi nations will also be able to pick, through event, which school they follow.

Two questions:
Can Shia nations invite Sunni scholars (and inversely)?

Yes, Scholars of heretical schools can be invited, but with a low piety requirement.

I'm really hoping for some changes or new mechanics to Persia, loving these Muslim changes

In one of the future dev diaries we'll take a look at the Persian situation.

@DDRJake

Can a "hated" school exist within the same major denomination? Ex can Maliki school hate the Hanbali school? If so does that change how piety is calculated for DOWs? Will I gain piety for declaring on same denomination but rival school?

Also for the Religious Followers\Enforce Religious Adherence actions, you said that will change piety by 50. Is that resetting piety to 50 or reducing by 50 points from you current piety score?

Schools can hate each other, even within the same denomination, as can schools from different denominations come to respect each other. Piety however, is still dependent on fighting heretics/heathens or same-faiths.

The piety change always brings it 50 towards the centre.

is this payed fetures are part of the free update ?:)

Legalism/Mysticism and the accompanying new events are free parts of the 1.23 Update. Muslim Schools and the abilities to Call on Religious Followers and Enforce Faithful Adherence are part of the expansion which will accompany 1.23.

If a nation other than muslim converts how is it its school picked ? Lets say commonwealth changes to sunni will it get a choice to pick a school or will it get some school matchin their national ideas and ambitions ?

They will get an event shortly after their conversion to pick a school from their respective faith.

Maybe we get updates culture and religion maps for the middle east next week?

Duly noted.

To anyone who wants to discuss trade goods, feel free to post trade good suggestions in the suggestions forum :)
Also I will note that there will be new trade good events for all the new goods, and some old prices might have been tweaked a bit as well...

Glass in 1444 is mostly places where early glass or forest glass was made. Glass is also a trade good you'll see grow in worth over time a bit (actually the price of glass will be adjusted up to 4 times and not necessarily only upwards).

I don't know if this has already been asked, but will there be more price-change events for other trade goods? I perhaps even events that do not trigger every game for more variety?

Even as it is there are price change events that don't trigger every game. Some were even so unlikely that I tweaked them a bit to actually show up a bit more.
But some of our new events also change the older goods, and some of the old events have had their effects tweaked.
Prices have been tampered with a bit in general, not only for the new goods. But most significant new price changes will be for the new trade goods themselves.

The missionary conversion strenght should be down to 2%, and the tech cost reduction should be changed to something less over powered. Coptic is still the best religion even without these changes.

Just to be clear: those bonuses from piety have been in game since release.
What's new with the dlc would be the school bonuses and the piety actions on the far ends.

In the era EU depicts at least Wahhabism is more or less sprung from the Hanbali school. I wouldn't presume to be very knowledgeable on the various moments today.
Wahhabism is very late game though so there's not a lot of flavor tied to it (it's not considered it's own school by the game for instance) :)
