Soc 12 is small c baronet
0-9
A gentleman (10)
B Knight (11)
c baronet (12) <-----
C Baron (13)
D Marquis (14)
...
So with incredible luck... 2d6 =12(c), 2d6 =12 ->13(C), 2d6+flux >= 12 ->14(D)
and 1/6 chance per roll on table one, average 4 rolls a term ... 66% chance per term if using all rolls on table 1 for a +1 soc. You technically could be a grand duke in five terms... as an unskilled 5 term noble. Of course this character already has horseshoes so potentially arch duke in 2 terms with three skill rolls for other skills...
So the rolls would be
Character base stats c6 2d6 = 12
Career promotion 2d6 =12
Career promotion 2d6 =12 + flux for 13
Then 6 6 6 6 for skill rolls term 1 on table 1
Then another 6 on same table...
Actually:
Soc 12 is both small "c" (baronet) AND large "C" (Baron)
0-9
A Gentleman (10)
B Knight (11)
c Baronet (12) <-----
C Baron (12) <-----
D Marquis (13)
e Viscount (14)
E Count (14)
f Duke (15)
F (Subsector) Duke (15)
G Archduke (16)
Those letters are EHex: "c" and "C" are both 12, "e" and "E" are both 14, etc., but they are fractional ranks within a particular Social Standing rating (i.e. one ranks "with but after" the other).
So rolling equal or greater than Soc for elevation, you can get to C6/Soc=13(D) via regular elevation, and possibly to C6/Soc=14(e) with elevation+FLUX if you are lucky.
So with incredible luck...
A Knight (B) rolls 2d6=11+ --> Soc 12 (c/Baronet),
A Baronet (c) rolls 2d6=12 --> Soc 12 (C/Baron),
A Baron (C) rolls 2d6=12 --> Soc 13 (D/Marquis),
A Marquis (D) rolls 2d6+flux=13+ -->Soc 14 (e/Viscount)
Btw: do you know book and page number for the rule that limits c6 to E or less without referee
Nowhere. That is merely the practical limit to Noble elevation thru the Noble Career (as demonstrated above) thru Intrigues, as opposed to C6+1 Personal Characteristic advancement (of which all Careers may partake, including Nobles). The standard maximum (for humans) for any stat unless otherwise specified has always been Stat=15 (==> C6/Soc= f or F).
