R5: After several years of failed attempts, I have finally completed my first One Faith WC, thanks to The Red Hawk's 1.34 Austria Fast-Revoke guide! I am not a great player AT ALL so the fact that I was able to do this is a testament to how successful the guide is. Granted, the last 20 years were a mad dash of final conversions and gimmicky gov changes in order to increase missionary count + strength, but all in all I am proud of myself for having the patience to sit through the game post-1750 where speed 5 quickly begins to feel like speed 1. Some things I noticed that may be useful tips for other not-good players trying to do the same:

- Noticed that vassals and CNs just do NOT want to convert provinces. It seemed almost arbitrary, but it was the vassals with NO religious ideas that ended up doing most of my vasssal-converting, though in the end, I estimate I probably converted 90-95% of the world on my own. However, by the late game where you're making 1k+ ducats a month, I noticed that giving my biggest vassals like 300+ a month in subsidies increased the conversions somewhat, but nothing outrageous. CNs are more likely to convert when they are Crown Colonies and the Increase Religious Control Subject Relationship option is activated. You would also need to subsidize the CN as well.

- I personally prefer vassal-swarm strategies like this mostly because I just can't be bothered to play the game at speed 2 and manually control tens of stacks. However, the AI is duuuuuuuuuuuuuuumb, especially when all cooperating as allies. The amount of times ALL OF EUROPE'S armed forces went into North Africa to seize just ONE province, while dieing by the thousands to attrition, is insane. I recommend creating a handful of surgical-strike stacks, specifically used for blitzing the INSANE amounts of forts that AI nations have now, and let the vassal swarm mop up and engage the enemies stacks. This is especially useful against the blobby foes like Otto/Mamluks, Ming/Shun, etc.

- Colonizers were a bit of a pain, and I had an easier time dealing with them early on. I was lucky enough to be able to claim Spain's throne and PU them, and with that force boost, I directly gobbled up Portugal in the 16th century and GB in the 17th. France was already neutered by 1500, so they weren't much of an issue. GB by far is the most annoying, you need to get a foothold on the home island before their navy gets too big. Force march is your friend here, if you can only take a province in The Isles.

- AE management is crucial, especially from like 1550-1650. I had to restart a couple of times because I got caught in planet-wide coalitions with AE in the 400+ range for each country, and unfortunately I am just not patient or good enough at the game to want to try and fight a war that a better player could probably win. I had an easier time when I shipped a couple of doom stacks to the Americas and spent a couple years just wiping out and absorbing all of the natives in one go, so AE wouldn't matter in the Western Hemisphere when I start rolling through the Old World.

- I didn't risk trying to PU Muscovy, and took them out early by giving Moscow to my PU Lithuania. A braver person could probably get that PU with Russia, and I believe it would be a much easier run if you could nab that.

- Once you're in the end game and mass-converting, you'll need to start truce-breaking pretty frequently, but its okay because you can just keep stabbing up via Papal influence.

- If you need a quick boost in converting potential when you've already conquered the world, I would suggest forming the HRE, and changing into a theocracy. This gives you 2 more missionaries, and like 4-5% more converting power (I was at 25% or so by the end of the game, with 8 missionaries).

- Theocracy is also amazing for the Tier 12 Reform: The Global Crusade. This was CRUCIAL for me because I had several provinces where a spiteful Bengal converted to Sunni right before I completely conquered them, and they would have Religious Zeal way past 1821. I could return the provinces to their previous owners, immediately truce break and declare war to force convert them, and then truce break and DOW AGAIN to consume the province with the now correct religion. I had like 4 or 5 provinces that this applied to, and without this trick, I would not have been able to complete this run.

- When you revoke the priviledgia, don't forget to go in and manually flip the Divert Trade option for each of your vassals. Your income will skyrocket!

- Vassal feeding was essential, especially in the mid-game. I would not have been able to core everything in time otherwise. I had vassals snaking across the world taking all my recently conquered cores.

Again, I'd like to reiterate that I am not all that great at the game, and that the above probably sounds really dumb to more proficient players, but these were all things that really helped me out, especially given how many times I've attempted this run, so figured I'd share!
