Role playing aficionados will already be familiar with the d20 die, but combine that with the powers of a magic 8 ball and you get the Magic d20 of Destiny. Just shake it up and let it tell you the future.
If you are bad at making your own decisions just let this D and D themed oversized die do it for you. It can take all of the blame for bad choices. If you get tired of asking it questions, you could probably just use it as a giant sized die while gamning.
The Magic d20 of Destiny is $7.99 from Thinkgeek.
