I found this online, not sure its the right way so im gonna stick to doing it
like u said as if it was an ability score.

The basic formula for Comeliness is as follows:
[ ( Str + Con ) / 8 ] + ( Cha / 2 ) + ( 3d6 / 4 )

Hp... Since we r gonna make 3rd lvl chars we only do the first lvl full then
roll dice? or all lvls?

About gold.... I dont think 100gp per lvl is the right way...

Warrior -> 5d4 x 10gp
Wizard -> (1d4+1) x 10gp
Rogue -> 2d6 x 10gp
Priest -> 3d6 x 10gp (Priest can only buy equip and goods but must return all
but two or three of his remaining gold pieces to his superiors)

And when u say doesnt really matter to get too much into details u mean like
nonweap prof? or what kind of details...

And a question about my char, i was wondering if u r gonna allow the complete
wizard's handbook... im interested in the witch kit.. not a 100% sure but so
far it seems really good :P

I think thats it for now, thanks :D
