Hmm Lemuria seems like a ton of fun with a triple bless. I tried D9, F9, N9 and my Censor could solo 400+ sized armies in early/midgame. I cleared multiple thrones using only that guy and the only equipment he had was from the death battles, where he killed all kinds of giant nastiness.
I eventually left him on a throne in the middle of hostile territory where two nations were constantly sending enormous armies at him while he was in -5 dominion and he survived for nearly 30 game (not battle) turns before he was killed.
In late game when armies starts using bigger spells he falls off a bit but well, not a bad deal for 25 death gems. I did have to take negative 3 scales except luck, which was kept at 0 and a demilich with dom4 and awake. I have to experiment a bit more with it awake or not being worth it. It'll take about 6 turns before you can start producing mages otherwise, which is a huge huge amount of research time lost. You can turn your starting commander into a prophet, but he's not immortal and ethereal so as a thug, he'll be less impressive. Never tried using the 1h priest you start with as a thug, perhaps that could work due to the F9, D9 bless giving it a ton more damage and N9 bless granting it more HP while also being ethereal. Having an imprisoned pretender + misfortune 3 would allow a fourth bless. In theory, leaving a thug on all provinces should easily be doable with Lemuria and looking at the effectiveness of my first experiment, they should be more than capable of dealing with whatever nastiness pops up in a territory. I wonder what the fourth bless should be, I'm thinking W9 or E9. E9 would allow more skellie spam and general tankiness, while W9 would also increase tankiness through defence, while also allowing 1.5x more attacks and reaching the enemy earlier.
Gee I just noticed I started rambling quite a bit. Still posting it here to see what others think. Probably would work horribly in multiplayer and dom kill is a valid threat, but it seems doable.
