The caster rubs his hand with bone dust, draws a pentagram in the air and concentrates on the spirit.
At the moment the ritual is finished, the service spirit appears in the place of the pentagram. The service spirit performs a simple service for its master, the service can consist of max Power things. The service spirit is not able to directly harm a living being or object. Examples of services include delivering very short messages (max Power words to one person, or 1 word to a total of Power people), notifying the caster when one of Power certain events occurs, or even gathering Power apples.
