Contrary to the name, the staff was neither made by, nor endorsed by, dwarves. The Dwarving Staff contains a bound magic spirit that knows the spells Tap INT and Tap SIZ. When twirled counterclockwise, the spirit in the staff casts these spells with Intensity 15, Multispell 2, and when the staff strikes someone in combat, it drains 5d6 SIZ and 2d6 INT from the target. MP gained from this attack are used to fuel the next attack, and so on, until insufficient MP are remaining to perform this function again.  Some variations on this weapon include MP storage, or additional Taps (CON and POW are both popular). The staff is also generally armored (via Strengthening), and often carried Boosted Damage as well.
