A Scryerskull is a type of Servo-skull deployed for tactical advantage on the battlefield. The Tech-priests of the Adeptus Mechanicus take the assessment and exploitation of battlefield resources very seriously indeed -- so much so that many of them continue their work in this role beyond the point of death as Servo-skulls dedicated to tactical analysis, transmitting a torrent of binharic code outlining battlefield strengths and weaknesses back to their masters.
