Chaos is an All for All battle, which rewards its competitors in Knight. Everyone gets EXP based on how many kills or deaths they had, and also the top 20% get Blue chests, top 40% get green and top 80% get red. They can get one chest, for example top 20% get only blue, not red+green+blue. You can buy knight gold on our site if you do not have time to farm gold.
By the way you can get this Chaos Oracle thingy every time you go to Chaos, and when you get 10. Also you can exchange them for wings that last 1 day and give you a random bonus, like +200 HP,
Now you might have noticed those blue spinning boxes in Chaos. Those boxes give you special skills like Killing Blade, Drain Restore or Light Pit. And you get those skills depending on how good or bad you are doing. We think that all those below the 40% receive the Killing Blade, those in the 20%-40% receive the Drain Restore and the top 20% receive the Light Pit skill. Use our knight online gold service will make the game more interesting.
