Calling all spies! I am seeking the community's guidance and knowledge about how spies work. A discussion about their benefits and any secrets would be most welcome. I played CiV: BNW and really enjoyed the espionage system in that but I am struggling to fathom how to really make the most of spies in Civ VI. How are people finding using spies in Civ VI? Has anyone found them particularly helpful? One specific question, please tell me how promotions work? I've noticed that spies operating in a foreign city can 'gain sources' so that all spies operating in that city get a boosted percentage change at other missions. Are there any permanent promotions like units and religious units get (or levels like in BNW)? I feel like I am missing something. I find the Listening Post missions useful but these appear to sometimes not increase the access level of other civs. This may, however, just be coincidence as the level may have dropped for some reason without my knowledge whilst the mission is taking place. How are people finding counterspying? I've yet to catch anyone spying on me or receive any notification about the good work of my counterspy. Thanks all.
