At the very beginning of the game, after you fight Behemoth, you will be quickly brought to the second chapter. You'll have a scene with a character named Kunsel, who will brief you about all sorts of important stuff. He'll then tell you to check out the nearby supply pod, where you'll find a Bronze Bangle. However, if you check the pod again, and again, and again (twenty more times, in fact), you will find an item called the Cursed Ring.

The Cursed Ring is a statistical powerhouse, raising your HP, MP and SP by 10%, as well as increasing all stats by ten points. However, you can't use limit breaks, you can't level up, and you can't access the DWMs during battle, meaning it's both a blessing and a curse!
