I wanted to suggest Red Mages being able to see the charge/"durability" of an empowered ring, similar to how tailors can now see the durability of clothing.

Likely with similar criteria, being at least journeyman (possibly expert) to be able to see its current condition. This way, players would be able to have some degree of notice before their jewelry loses its empowerment. It would help prepare for replacements since they're a very considerable investment, especially finer gems or meteorite settings.
