Is it possible to create new artifacts that increase the combat characteristics of machines? For example: - Engineer's ring (+10 to the defense of all machines) - Pendant of Machine Call (+10 to the initiative of all machines) - Necklace of Strength (+10 to the attack of the ballista) - Siege Engineer's Boots (+1 to the speed of all machines) - Armor of Courage (+100 hit points to all machines) If you collect all 5, you get a set: God of Machines. In this case, machines influence the parameters of tier 1, 2, and 3 units, increasing their attack and defense by +2.
