After listening to Benson's speech, Vicente was not confused by his master's terms and analysis.
Each item produced by magicians would have efficiency, progress, or purity, in short, a characteristic that would show how good the item was for magicians of the same stage as the item's grade.
For example, purer pills meant that they were better concerning the impurities but also more effective for magicians near the peak of their stage. In the case of blacksmith-crafted items, efficiency concerned how well the item would defend or deal damage when worn.
Armor with 100% efficiency would be impenetrable to magicians of the same stage as the item's grade, using weapons of a similar grade with less than 100% efficiency.
This was also an important attribute to know how much maintenance you would have to worry about.
