What is up with this Lux Invicta playthrough?
Start with a dude that goes by the name of Kolli. Kolli had decent stats, but nothing good. Over a couple of years, the court priest saw a crapton of good omens, giving a ton of stats and traits. The dude was a proper Prophet though, cause Kollis firstborn son was born a genius, and over time was raised to have 24 diplomacy. Kolli then holy wars a nearby duke, who is exactly as big as him, and wins easily. But then disaster strikes. Right before his death, the Prophet predicted doom, and Kolli went crazy. And that prophecy came true as well, as with the victory in the holy war, Kolli inherited a different war. In an attempt to not lose a county, Kolli attacked the enemy army. In the battle, Kollis army gets destroyed, and Kolli gets maimed. He dies shortly after the 16th birthday of his son.
Son has to sit around with negative authority for a while. As a coincidence, while surveying the realm to boost my authority, he teaches a village to fight bandits, and wins an awesome battle, netting him a whole 5 authority, which happened to just enough to push authority of the threshold and greet me with a cheerful message that he is no longer disrespected.
Then disaster strikes again. The same guy as before declares another war. I still hadn't regained enough troops to fight, so I had to surrender. Son becomes a lunatic shortly afterwards. And yet the luck doesn't stop for him either, his good stats give him a lot of authority, and after a lot of completely normal daughters, his first born son is both a genius and has a powerful voice.
So basically, a short line of rulers that go crazy at the first sign of trouble, but win the genetic lottery with every generation.
