Construct

Constructs are either animated objects or any type of artificially constructed creatures. Most constructs are non-intelligent automatons with neither a soul nor a purpose beyond service to their creator. Because few constructs are truly alive, usually operated only by a "spark" of life, most are immune to attacks that target the living. These "dead" constructs possess low-light vision and darkvision and are immune to mind-altering, poison, sleep, paralysis, stunning, disease-related, and death effects. Neither do these constructs require sleep or take part in any metabolic activities, such as eating or breathing.
