Unseen Servant

The unseen servant is a non-visible valet, a butler to step and fetch, open doors and hold chairs, as well as to clean and mend. The spell creates a force which is not strong, but which obeys the command of the magic-user. It can carry only light-weight items - a maximum of 200 gold pieces weight suspended, twice that amount moving across a relatively friction-free surface such as a smooth stone or wood floor. It can only open normal doors, drawers, lids, etc. The unseen servant cannot fight, nor can it be killed, as it is a force rather than a creature. It can be magically dispelled, or eliminated after taking 6 hit points of magical damage. The material components of the spell are a piece of string and a bit of wood.
