In addition to the normal male and female choices, classes exist which are unique to certain characters and may become available only if the plot takes a particular turn. Only Females of the Law alignment can become Angel Knights, while changing to a Lich requires the character to have the requirements and be equipped with the Undead Ring, a rare accessory item that is destroyed during the class change.
Additionally, the Angel Knight and Lich are only obtainable when a character who has the right qualifications dies in battle. Making a character a Gunner is a permanent change.
Concerning the 'Gunner' class, once a character has changed into this class, they cannot change to a different class. By leveling up correctly, they can later progress to the other male or female classes, although most advanced classes are limited to certain alignments - lawful, neutral, or chaotic. Most human characters begin as either amazons or soldiers.
