In the original release of Maple Story, players start as a Beginner. Only after reaching level 10, they can transition into their first job by talking to the respective NPC in the area:

  • To be a Archer, Athena Pierce in Henesys.
  • To be a Warrior, Dances with Balrog in Perion.
  • To be a Magician, Grendel the Really Old in Ellinia
  • To be a Rogue, the Dark Lord in Kerning City
Correction

Um actually … Players can choose Magician as a job once they hit level 8.

A patch later on standardized it to be 10.
