Archetypes represent the class system within Kensei Online. Players are prompted to choose an archetype during character creation and this decision cannot be altered in any way once it has been chosen. Different archetypes focus on different aspects of combat. Archetypes affect the proficiency of weapons and health gains and regeneration per level. Players usually refer to their classes as a "type," such as a soldier-type or a ranger-type. See Category:Archetypes for a full list of archetypes in the game.
