Clavats are jack-of-all-trades good in any situation. With their high Defense, they can take damage, and because they do not excel in a particular area, they can be either magic or melee users. The Clavats appear in almost all cities (Leuda appears to be the only exception) and are almost the exclusive race in the Fields of Fum. Being the main inhabitants of Fields of Fum, and given the fact the fields supply most of the world's produce, this would make them an important race, albeit not one with much strength to conquer like the Lilties.
