[Mysterious Dark Lord v3.2]

Staff of the Nine Elements

This is a high-tech item, made of refined metal and elegant crystal. To a low-tech person it will be quite beautiful, while it's name will be a mystery.

The staff is an amazing technomagic item that creates nine distinct elements. Unfortunately these are all trans-uranics with half-lives in microseconds and in amounts measured in micrograms. To an observer, it will make a few sparkles and that's it. It does this once every eight hours.

A scientist of TL7+ who figures out what it does will figure out that the possessor of the staff is being exposed to the radiation and decay products of the staff on a continual basis. This makes anyone who hangs around the staff susceptible to exotic chemical poisoning, radiation sickness, cancer, and possibly more exotic issues. It also makes the possessor and his companions really easy to track via high-tech means.

(Of course, if you get a giant monster to swallow it, you guarantee it's death in a week or two.)

The next name ... Gwoves of the Wascally Wabbit!!
