I don't know if it's an error, but:
"Occupational Skills: Read/Write (any) +50%, (Sorcery
spell) +10%, Orate +25%, Lore (any) +30%, (Sorcery spell)
+20%, Library Use +10%, (Sorcery spell) +10%, Lore (any)
+10%, Meditate +20%." (p 70)
So is it correct that a Philosopher gets one Sorcery spell with +20% and two Sorcery Spells with +10%?
Or would the first Sorcery spell bonus have to be higher?
