More videos of Ragnarok Odyssey were released on YouTube recently and the official site is updated with some new gameplay details.

Card System
You can use cards as part of the battle strategy and also to build up your characters. These cards are obtained from the enemies that you defeated. Multiple cards can be equipped which allows your characters access to special skills. There are over 400 skills in this game so prepare to grind your way to obtain all of them.
Job Change System
There are basic jobs included in this game, which includes sword warrior, assassin, hammer smith, mage, cleric and hunter (videos of the latter two are posted below). Once you have progressed far into the game, you are allowed to change your character’s job. Do take note that when changing jobs, your character will retain his currently parameters which is why it’s encouraged that you change your job to match the upcoming quest.
