EU4 multi-tag campaign planning: optimal religion switching path
I’m planning a new campaign in Europa Universalis IV.
The end goal is to form Russia, but the planned progression is highly layered and focused on stacking permanent modifiers through tag-switching.
I would start as the Teutonic Order, take the Crusader path, and obtain the modifier granting +15% cavalry combat ability and a 50% cavalry-to-infantry ratio. From there, I would trigger the Danzig disaster to form Danzig, then form Pomerania for the +10% cavalry combat ability. After that, I would form the Hansa for the +5% discipline, and then form Poland for its national ideas.
At that point, the plan becomes more complex.
I would like to form Armenia (for the permanent discipline modifier and culture conversion bonuses), and then Georgia for additional permanent modifiers. However, this would require switching religion to Coptic and then Orthodox.
Ideally, I would also like to form Prussia at some stage after this, although I am unsure whether any of the Danzig mission tree allows forming Prussia without meeting the usual religious requirements.
Finally, I would transition into Russia, potentially while converting to Zoroastrianism.
My main question is: what is the most efficient method to chain multiple religion switches in this sequence?
I recall seeing a video mentioning a “Jewish temple” event that supposedly allows rapid religion switching—does something like that exist, and could it be used for this kind of setup?
