Above +5, new branches start to appear. If it's merely about enhancing magical attributes, then it's Legendary Equipment. Whether it's +6 or +8, they are just more powerful Magic Items, essentially still mundane Magic Items.
However, once infused with Divine Nature Force, even if it's only +6, it will transform into a Divine Artifact, although just a sub-divine artifact.
In terms of overall attributes, Divine Artifacts are not necessarily stronger than Legendary Equipment, but the exclusive abilities of Divine Artifacts are usually extremely powerful.
Between Legendary Equipment and Divine Artifacts, there is another type of equipment called Ancient Inheritance Equipment.
This equipment is essentially Legendary Equipment, but it possesses certain features of a Divine Artifact, absorbing faith and beliefs for its use, and even making itself stronger.
However, it lacks the Divine Nature Force infused by All Gods, so it doesn't count as a Divine Artifact.
