I’ve personally been having a blast playing secret societies, even if the AI is a bit daft with it. In the games I’ve played, I typically try to pair my society with my leader, and there’s a few combos that are awesome to pull off. To name a few: Owls with RR Teddy This one can be nuts. Owls give an envoy when you send a trade route. Teddy gets 2 envoys whenever 1 envoy is sent to a CS with an active trade route. If you send a trade route to a CS that wants one as it’s quest, it gives 4 envoys instantly. Owls also combo nicely with Hungary, Georgia, and Pericles, but especially with RR Teddy. Owls also combo nicely with Mali with the bank. Hermetic Order with Scotland, Russia, England, Brazil, or Sweden These civs have a very strong great person play. Leylines give yields equal to every GP earned (not even used). Leaning heavily into Oracle, Divine Spark, or Bologna if available means that you can have very powerful single tiles in your empire. It should also be noted that while leylines cannot be built upon, they can be settled on, granting nice bonuses to adjacent districts and not “wasting” the tile. Voidsingers with Khmer, Eleanor, Kongo, Poland, or Rome This one has gotten a lot of attention, but yeah, anyone with strong relic play should pay attention to this one. And Trajan obviously likes this one to give him a surprisingly strong faith economy. Vampires with ???? Obviously meant to be good with warmongers, there synergies are a bit harder to spot. I haven’t played with them yet. Have you found any strong combos?
