That's precisely how it works. The problems are when the current ruler doesn't have a son or grandson alive (but it *should* default to great-grandson).Oh, and I'm curious: if succession passes to a cousin or uncle or something, is it always traced through the father of the current ruler?
Steward is probably closer to Treasurer than Sheriff.Chancellor => Diplomat
Martial => Army Reformer?
Steward => Sherrif? Treasurer?
Spymaster => Spymaster
Court Chaplain => Theologian
There are levels in CK2 as well, but anything beyond a certain value (somewhere around 13-15, I think) doesn't have any effect for a lot of them (Forge claims, for example, is capped slightly above 10%, and it doesn't matter how skilled your Chancellor is beyond that point). I've not looked at the numbers very closely, but Spymaster is definitely affected by his intrigue skill. Pretty certain Court Chaplain is capped too (county conversion and such) -- but I can check that later. Anything above 20 is extraordinary though (in CK2), and should be treated as such.Their level will depend on their relevent CK2 skill. If your CK2 chancellor has 0 diplomacy, then he will be level 1. If however he has the greatest dimplomacy level in the world (either THE greatest diplomacy level in the world, or greater than some arbitrary cutoff) then he will be level 6.
0-5: 1
6-10: 2
11-15: 3
16-20: 4
21-25: 5
26+ : 6
Maybe?
Of course, you can shift them around somewhat -- maybe you want a it to be 11-13, 14-16, 17-19 and 20+ instead? /shrug
I wonder if I can get at the skill value data somehow, we could get a nice view of what numbers we're actually looking at (instead of super-humans bred by players).
