The Scryerskull Perspicatus is a sacred relic of the Adeptus Mechanicus sometimes deployed with the Tech-priest leading their military forces to enhance his or her tactical acumen. This tiny Servo-skull reads the battlefield as a cascade of binary code. Those who gather and process its papery expulsions see not only the treasures of the battlefield, but also the weaknesses of those enemy vehicles found wanting in the Perspicatus' sight. It is then possible for the commanding Tech-priest to direct his forces to more effectively exploit these perceived vulnerabilities.
