Dear ryciebani666,
Let me just start by saying: I absolutely love this Mod! I think I have never fallen in love with a mod as much as I did here. It's just incredible how much content and flavour you have added to the game. And I have never been able to fulfill my power fantasy as much as with your mod :D

That being said, I want to contribute by reporting some (non-gamebreaking) bugs / balancing issues that you still might want to fix:
1) It's possible to have multiple mage towers by either building them all at once after getting multiple counties that have the empty building slot or by simply taking different counties with them already built.
2) Much more problematic: You can also upgrade multiple mage towers to level 2 by doing all the upgrades at once. I think I had like 15 level 2 mage towers in my latest run.
3) After researching the magic singularity MK2, I was suddenly able to start magic triangulation and search for artifacts again - but without getting any results. Probably because the game sees I have a missing Singularity MK1, but there is none available in the world.
4) The ring of death does not properly work as a magical artifact - meaning it is not obtained by imprisoning the owner.
5) It's rather easy to get to +100 opinion with all three special enemies you added (Bael with palace coup, the Archmage that wrote Necronomicon and the "Hellhound" that has the Ring of Death). Therefore it's even possible to befriend them. I had all of them as vassals / councilors for some time. However, they will still try to mess with you which is kinda weird but maybe on point? Personally, I would love to be able to make them my minions proper (either by Domination spell or by just making clear that they are outmatched).
6) Small issue: There is no proper way in game to understand that one has done all special magic research projects. I only understood this when consulting the cheat sheet you provided. It would be great to get a small message that no further special projects are available.
7) It's possible to do the unique mage legend as often as you want - though this is nice to do the magic research much more often, it's still weird.
8) It's possible to permanently get all the named demons except for Hecate as courtiers. Not sure if this is intended or not, but it's a bit funny to not really have anyone open for summoning except for Hecate and minor demons.
9) Talking about summoning: In a previous run I once summoned Asmodeus I think, telling me how pathetic I am... This time, maybe because I got the scepter of hell early, I never encountered him. If this is the case, it would be great to still have unexpected summons even when being able to summon by name.
10) I never got the god-emperor title / nickname - unsure how or if this is possible. I feel like I did all late-game stuff possible.

Thank you so much for the work you put into this! I would love to see further updates in the future, it's just so much fun to play this mod!
