Missed getting the Master’s Secret Script because you didn’t pre-order Lost Odyssey? Don’t worry. The extra item is available right now with a little help from an international Xbox Live account. If you hop online with an Asian or Japanese Xbox Live account you can download the “bonus item two piece pack” and immediately get access to the Master’s Secret Script and Weapon Guard II regardless of the game’s region. Let me explain that again: you can download the Japanese key with a US version of Lost Odyssey!
As an added bonus you can even get access to the second piece of downloadable content if you have an extra 200 Microsoft Points lying around in a Japanese Xbox Live account. As you can see in the screenshot I have Kaim equipped with the Killer Machine ring, an item that is currently unavailable in any region outside of Japan. It works just fine (except it makes the game a little too easy!) and the Memory Lamp is sitting in my inventory until I find the Nautilus.
