Expeditious Excavation

Transmutation [Earth]
Powerful telekinetic forces take hold of all loose rubble, stone, and earth in a space up to one 10-foot-cube per caster level. These forces push aside the stone and rubble, rebuilding the stone walls and floors and ceilings of the collapsed chambers and then holding the rebuilt room sound and true for the spell's duration.
Range: Close (25 ft. + 5 ft./2 levels)
