"The Staff of Magnus, one of the elder artifacts of Tamriel, was a metaphysical battery of sorts for its creator, Magnus. When used, it absorbs an enemy's health and mystical energy. In time, the Staff will abandon the mage who wields it before he becomes too powerful and upsets the mystical balance it is sworn to protect."
This artifact can be sold for 30,000 or be donated to the Museum of Artifacts in Godsreach. 30'000 is the maximum amount of gold Torasa Aram, the curator of the museum, is willing to spend for one artifact. After giving it to her, the staff may be seen on display within the museum.
The staff has appeared in four of the five main Elder Scrolls games to date, Oblivion being the only exception.
