There are a total of nine primary professions a player may choose from. There are seven combat professions, four crafting professions and one entertainer profession. In addition to a main profession, there are four auxiliary professions that characters of any profession may pursue: Pilot, Politician, Beast Master and Chronicle Master. Each profession has an expertise system that allows them to extend the fuctionality and/or performance of their respectvie professions while allowing the player to create a unique skill template and play style.
Characters may change primary professions (and expertise) later in their career by visiting a profession counselor. The category of each profession affects the level the character becomes in the new profession. The first main profession change is free, however subsequent changes increase the fee up to 25 million. Every month, this "change counter" is decreased by one. So practically, a character can change his profession for free once a month.
