At the moment, here is my thinking on what classes to include in the game:
Budoka (Martial Artist): expert at weaponless hand-to-hand combat, will be customizable to emulate karate, jujitsu, aikido, sumo, or whatever. Will have access to some weapons, probably no armor. Special Abilities: a mix of Maneuvers and Tricks. Spells: none.
Yamabushi (Mystic): religious hermits who practice asceticism to gain physical endurance and magic powers. Access to limited weapons and limited armor. Special Abilities: lots of Secrets. Spells: yes.
As always, Maneuvers are combat related abilities, Tricks are for exploration and interaction, and Secrets are magical abilities.
