"I am not a dwarf anymore." - LordOfTheUndead
The Staff of Defile is a variation of the Dwarven Shovel. It is used by LordoftheUndead.
The Staff of Defile is a diamond shovel that digs faster and deals slightly more damage than the normal shovel (+4 attack damage as opposed to +3). It also has the appearance of being enchanted, though this has no benefit whatsoever.
A dwarf must be LordOfTheUndead to receive the Staff of Defile
