Millennium Item
![User Image](https://i163.photobucket.com/albums/t320/tails_rox/MilleniumPuzzle1.jpg)
Advantages: Difficult to find out. Can't be charged with murder because your enemy is still physically alive. Your opponent is judged by the Darkness, so your guilt is limited because if your opponent loses, he most likely deserved it.
Disadvantages: Will have to play an overly complex and long game for effect to take place.
