Hello everybody. When rounding off last week's Dev Diary, I was planning on bringing up a certain mechanic which has everyone who has touched it dazzled and not wanting to ever be without it. Something about Diplos and building with macros, I forget. Those who have been poking around the store page and done some leg work have been speculating over it.In view of that and how I do love to read speculation, I will let you stew over what it could be for a couple weeks and instead take this week's Dev Diary talk about the first of our religion overhauls:It's high time Confucian got the spotlight. It's been a troubled child of religions in EU4, existing almost exclusively in China and Korea without its own mechanics. For owners of Mandate of Heaven though, that changes with the introduction of Confucian Harmony.Confucian nations will have a value for the Harmony in their nation. As it grows, so too does their tolerance of the True Faith. By default, it grows by one every year, faster if they keep stability high and complete Humanism Ideas. Low Harmony will reduce tolerance of the True Faith as well as causing higher costs in development and hurting Meritocracy.So keeping your nation's Harmony high will ensure good times for your nation, but there is a choice to be made. Converting provinces in your realm will cause Harmony to fall, scaling on the development of the province you convert, so at least in the short term, wiping out heathens may cause rough times for your nation.For Confucian Nations though, they have the unique ability to Harmonize with other religions. While Tengri nations have the ability to instantly Synchronize with one other faith, Confucian nations can gradually adopt and mesh with many religious. For Heretics, they can choose to gradually Harmonize with that religion, treating it as the True Faith. For Heathens, this process applies to that religious group.Harmonizing with a religion is a process taken in the religious tab. A religion or group to Harmonize with is selected and the process of adapting with their beliefs will begin. This process will cost 3 Harmony per year, so more stable empires will have an easier time adopting new faiths, and will tick up a progress bar from 0 to 100 by 3 per year. Harmonizing is a long process punctuated with events, but the end result will be a religion or religious group that is treated as True-Faith for your nation for the rest of the game (Assuming you yourself remain Confucian)Each Harmonized religion also gives a nation-wide bonus for 25 yearsMy totally Legit Korea in the above screenshot will now enjoy +2 tolerance of the True Faith for 25 years. Some of the other religious bonuses include:Muslim: +10% Trade efficiencyShinto: +10% Infantry Combat AbilityJewish : +33% institution SpreadWe'll leave the others for you to explore, and next week we'll discuss another religious mechanic added in Mandate of Heaven
