Amplification magic treasure was a conventional term widely used by ancient cultivators and Spirit Tamers, not a classification recognized by the Artifact Way itself.
Corresponding categories included storage magic treasures, summoning magic treasures, divine ability magic treasures, and others.
The Ice Soul Divine Mirror in Fang Qianyuan's possession was a typical divine ability magic treasure, while the Night Spirit Ring and Moon-Reflecting Wolf Fang Chain were summoning magic treasures.
Amplification magic treasures were characterized by formation arrays and restrictions associated with particular Dao Paths. Some powerful ones could even harness the power of the laws, greatly increasing the wielder's control over the origin energy of the corresponding Dao Path. When the wielder unleashed divine abilities and spells, not only would their range expand and their duration increase, but their power would also rise considerably.
In other words, they could comprehensively amplify and strengthen a particular Dao Path.
Divine ability magic treasures, meanwhile, activated fixed divine abilities and spells, allowing their wielders to use them without having to learn them.
Their drawback, however, was that these divine abilities and spells were too rigid, and their power was also limited.
To explain it in terms of mundane weapons, it was the difference between bows and crossbows and firearms.
Bows and crossbows relied on physical strength. In strong hands they became stronger, but in weak hands they likewise became weaker.
Firearms used gunpowder to launch projectiles. Even a three-year-old child could kill an enemy with one, but their method of operation and power were fixed and could not be changed.
Some powerful divine ability magic treasures could break through those limits on power, but they remained restricted in form and could only be used according to the treasure's own characteristics.
Neither category could truly be called superior, for each had its own strengths
