Servant Horde

With this spell, the wu jen creates a number of invisible servants similar to the unseen servant spell. The number of servants that can be created is equal to 2d6, plus 1 per level. These servants have all the limitations of the unseen servant except that they can be used for common laboring tasks as well, provided they are carefully directed by the spellcaster. They could serve at a banquet, help dig earthworks, row a ship, act as porters, or assist in a farmer's fields. A 9th-level caster creates a servant horde that lasts four hours.

The material component is a small stick crossbar to which many lengths of knotted thread are attached.
