Artifact's Ranks

I practically changed the whole artifact system as I found it difficult to find any information on the Heavenly Artifacts above Ordinary rank other than their names (Trascendance and Overgod, two mouthfuls) It won't change much other than how they address them, and some artifacts that were found during canon will have their Grade lowered but I want to know if you're ok with it or want me to go more with how canon went.

Earthen Fate Equipment:

They would go from Bronze to Legend rank.
