Refining Stones are peculiar ores discovered by humans in the Mythical World that can be used to refine a Professional's equipment. If the equipment refinement is successful, its effects will be improved to a certain extent.
The success rate of refinement, the number of possible attempts, and the amount of Refining Stones consumed vary greatly depending on the equipment's quality. For example, a Gray Inferior Apprentice Magic Staff can only be refined to +1, and each attempt requires one Level 1 Refining Stone.
Just like inlaying a Gemstone, it's best to use the exclusive skill 'Refinement' from the Blacksmith auxiliary Profession when using Refining Stones. This ensures a certain success rate. Of course, Fang Zhou, with his all-powerful attribute panel, was not bound by this restriction.
