A Cognis Flamer is an Imperial Flamer Weapon used by the military forces of the Adeptus Mechanicus which has been outfitted with a Cogitator. The spark-like anger of the Cognis Flamer's artificially intelligent Machine Spirit has been fanned to a roaring blaze. When under duress it will fight with incendiary wrath, even should its wielder be distracted.
