the three mind-based stats

[uglyvan]

i.e.
INT = Scholarship level x Tolerance
WIS = Understanding x Dedication
CHA = Might x Music

while

Creator = Scholarship level AND Music
Orator = Dedication AND Might
Thinker = Tolerance AND Understanding

( C,O,T all use a value in between 1 and, say 19;
then to build up a stat you multiply the sub-stats one with the other, like in
INT = Scholarship x Tolerance )

example

C 5
O 8
T 2

===>

INT = C x T ===> 5 x 2 = 10
WIS = O xT ===> 8 x 2 = 16
CHA = C x O ===> 5 x 8 = 40

well, this is for raw scores;
to retrieve the AD&D feeling you could depreciate stats using the max sub-stat which provides the BASE,
in the example top sub-stat is O=8, so BASE = 8;
in BASE 8, you bear only values of 1-8 x 1-8 so there isn't 11,13 etc
so a raw value of 40 will get depreciated to something like 25...
