Manipulate

Regular 
Allows manipulation of items larger than allowed by the Locksmith spell. Ropes may be untied, doorknobs turned, knives sharpened, handmill cranks turned, etc. The caster need not touch the subject. Any activity complex enough to require a DX penalty gives the same penalty to this spell.

Cost: 4 to cast and 3 to maintain for each 10 pounds manipulated. 
Time to cast: 3 seconds. 
Prerequisite: Locksmith.

Item 
Wand, staff, or glove.  
Energy cost to create: 600.
