The devil master is a monster in Might and Magic VI: The Mandate of Heaven. It is stronger than the devil captain, but weaker than the devil king. Devil masters usually attack in close combat, dealing 2D8+15 physical damage, and can inflict the diseased status. They have a 20% chance to use a ranged fire attack instead, dealing 4D8 damage, and also have a 20% chance to use the meteor shower spell. They are immune to fire damage, and can be encountered in Sweet Water and The Hive.
