The clockwork servant is a human-sized, four-armed, three-legged clockwork construct specialised in the repair and maintenance of other clockwork constructs. Some clockwork servants are magically imparted with intelligence equivalent to a human's and are said to serve in more complex roles than normal repair workers. Clockwork servants are about five feet tall and weigh over 400 pounds.
