Just like EXP gold is earned by posting. Difference is its only post outside of Root Towns and Lumina Cloth's Arena.
There is a certain amount you will gain from stepping into areas.
Open Areas - 5 gold
Dungeon * Open - 10 gold
Dungeon * Instanced - 10 gold
Quest * Instanced – 5 gold
Note each time you complete a quest (after telling your story on how it is completed) I will add 10x quest level to your character sheet.
Dungeons will have its own rewards for its clearing...
