Spells (3e)

The unseen servant is an invisible, mindless, shapeless force that performs simple tasks at the character's command. It can run and fetch things, open unstuck doors, and hold chairs, as well as clean and mend. The servant can perform only one activity at a time, but it repeats the same activity over and over again if told to do so, thus allowing the character to command the servant to clean the floor and then turn the character's attention elsewhere as long as the character remains within range. It can open only normal doors, drawers, lids, etc. It has an effective Strength score of 2 (so it can lift 20 pounds or drag 100 pounds). It can trigger traps and such, but it can exert only 20 pounds of force, and that is not enough to activate certain pressure plates and other devices. Its speed is 15 feet.

The servant cannot attack in any way; it is never allowed an attack roll. It cannot be killed, but it dissipates if it takes 6 points of damage from area attacks. (It gets no saves against attacks.) If the character attempts to send it beyond the spell’s range (measured from the character's current position), the servant ceases to exist.
