This staff was used by the human thief Nestor in an attempt to steal an artifact from some of his shipmates. He was subsequently killed by them and the staff has been in the possession of Umbopa ever since. Its most successful use to date was when Umbopa used it to push a Hill Giant off of a cliff in the Yatil Mountains.
