The samuraii is essentially a combination of warrior and mage. This is a soldier that has learned to focus their Chi energy in such a fashion as to cause supernatural effects such as super jumps, throwing small whirlwinds, or setting their sword on fire. They are often given to some focus or code that makes them excel as a magical warrior combination.
They can wear D2 armor, but always use a two-handed weapon or a pair of weapons. Samuraii are adept at dual wield. A samuraii may choose 3 weapons to be proficient in. They are allowed a bow, though they are more effective with a specialized form of training in close combat.
The samuraii train their bodies to function in perfect unison with the world around them. That includes whatever weapon they may use. As a result, they become masters of their chosen weapons.
It is not uncommon for a samuraii to possess elemental abilities. In such a case, then they would attune themselves to a certain element and gain mastery over that element just as they would over their chosen weapon.
They are allowed M1 on the meter for Magic Resistance.
