Not sure if this is technically "ownage" as such, but my character has a martial skill of 28. It should be 30, but he lost the 'Brave' trait, presumably because the game thought it would be entirely unfair if my capital county got a 150% boost (100% for the martial skill, 50% for capital) to the levy size as a result of this.
He assassinated his brother - my previous, unwanted character, I may or may not have manufactured the attempt by giving some of the participants council posts - to ascend to the throne of the King of Norway. Has the Tough Soldier education thing, and he's a Varangian, Viking and Berserker, has been involved in 3 of the personal combat things, one disappeared into the ether, one was a draw (I was alright with that, as the other guy was my marshal, despite him having a personal combat skill of 1 versus my 5) and the other one was a victory which would have got me the 'scarred' trait, had I not already got that from the healed wound that I got in the draw. Winter specialist and No Surrender combat traits, useful in Scandinavia...
The only annoying thing is that I'm a tribal government, unreformed Pagan, so I can't change my succession rules from Elective Gavelkind, and my heir has been in my prison for about 20 years and WON'T DIE.
