Excellent Rod of Engineering (Magic Rod)

A highly prized accessory for a military engineer, this plain, rechargeable, 2-foot metal rod has several different functions:
* On command, it extends up to 12 feet in length, while its surface roughens in alternating bands to allow the engineer to use it as a ruler and measure. This form uses no charges and is too slender and unwieldy to use as a weapon, though doing so causes the device no damage (nor can it cause damage, except to small insects).
* The rod always shows magnetic north on command, expending no charges.
* If rapped firmly against stonework, the rod will reveal to the user, by telepathy, the stonework's thickness and composition for no charges (this is useful for gauging the thickness of walls).
* For one charge, the rod may cast a dig spell with a duration of one turn.
* The power of the rod can function as a move earth spell for two charges per turn, or three if the effect is to move features rather than collapse them (as though an earth elemental were being used).
* A wall of stone (at 12th level) may be created for one charge.
* For one charge, the user can summon 10 unseen servants for one hour. They operate as the spell, but are each twice as strong as usual and can be used for stacking timber, grading roads, and other manual labor.
