Classes and their required skills and general channelling elements per weapon 
type (Information taken from Ramtieger's and Gundam4Fun's Romancing Saga PS2 
FAQs) by _davidovitch_

A ! behind a map skill means that skill gets a jewel discount when going from 
level 3 to 4 (Normally only weapon and magic skills have that in-class 
discount).
The map skills between brackets are not part of the class but DO enjoy the in-
class jewel discount when going from level 3 to 4.
