Jobs, Jobs, Jobs!
Learn multiple jobs for each class and power up. The more jobs known the more options players have in battle. Each job focuses on a different role (DPS, Heals, Tanking or PvP) and changing jobs is as easy as changing your gear!

Edit: 
The Arcane Saga team announced that the game would be closing its servers on September 16, though they had the grace to permanently close down the cash shop alongside the news post.
The developers at Netmarble explain that the game could not be sustained in its current form, and that they didn't think it would be manageable with a smaller staff. Players who have remaining NC (the real-money currency) can use it to buy titles that are currently available, or titles that the developers promise are on the way.
