Kutumhai

Kutumhai is the name of a heavy black staff made from black iron. it is covered in carvings of strange figures and unrecognizable symbols. It is too heavy to wield as a weapon and holding it feels like holding onto a mass of writhing snakes even if it doesn't visibly move.

Has strange properties such as levitation and seems to be capable of moving on its own, though inspecting it reveals no magic at all.
