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 toandWe'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 calledand high piety being depicted as devotion towards. 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 oneThe 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:So while your own School is set in stone, we allow Islamic nations tofrom 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.
