Call Poltergeist

This spell binds a minor spirit to an area. The poltergeist is an invisible, shapeless force that performs simple tasks at the Necromancer’s command. A poltergeist can run and fetch things, open unstuck doors, and hold chairs, as well as clean and mend. The poltergeist can perform only one activity at a time, but it repeats the same activity over and over again if told to do so as long as the Necromancer remains within range. A poltergeist can only open normal doors, drawers, lids, and the like, having an effective Strength score of 3. The poltergeist can trigger traps and such, but it can exert only 20 pounds of force, which may not be enough to activate certain pressure plates and other devices.
