The staff of the sands was a magical item that could be found in Zakhara, the Land of Fate.
These magical items were available in a wide variety.
These staves granted the following powers to a wizard at the expense of one charge: move sand, sand slumber, sand sword, stoneskin, and traceless travel.
The following powers consumed two charges for regular wizards and only one charge for sand mages: conjure earth elemental, desert fist, and create shade.
Sand mages gained exclusive access to the sink power at the expense of four charges.
Any mage holding the staff gained the advantage of the cool strength spell so long as they maintained contact with the staff.
