One of my favorite parts of any story are the deus ex machi.... I mean the wonderful assortment of magical/technologically advanced tools that the heroes have or obtain throughout their journey.

So, I want to know, if you could have one of these types of tools, what would it be and what would you use it for? Feel free to use anything from any source, it's all good.

For me, I'd want Jack Sparrow's compass. A compass that, instead of showing north, shows the direction of the what the holder wants most in all the world. It would be fascinating to see where it led me too.

...Yes I know it's not a very exciting pick.
