You can find the following scrolls in the Misc section of the Shop to change your character:
- Scroll of Renaming: change your game name.
- Scroll of Metamorphosis: change your character's gender, outfit and colors.
- Scroll of Rebirth: re-assign your stats.
It is not possible to change your race at the moment. The only possibility to do so is to Clear Data and start a new game from scratch. Then you can chose another race to see the game from a different perspective.
Note that this procedure will not remove your old character from our server, it will still be available for transferring or restoring (see Account Transfer and Restoration for more info). However starting a new game with the same race will overwrite your previous character.
