Berserker Staff

The Berserker Staff is an Asgardian weapon in Earth-199999 that sends its wielder into a wild, powerful rage. It is a long staff made of Asgardian metal inscribed with runes. It was brought to Earth during an undisclosed war by the Asgardian known as Elliot Randolph, who grew tired of the Staff and "fell in love" with Earth's beauty. He broke the Staff in three and hid the pieces in Ireland, Spain, and Norway to prevent anyone from abusing its power. This plan worked until late 2013, when a Norse paganist hate group began seeking out and assembling the pieces. Agents from S.H.I.E.L.D. stopped them, completed the Staff themselves, and took it into custody.
