Again, since you did not reply to my question concerning artifacts:Is Frodo flying through the air, firing disintegration beams out of his hands, after dealing with a nest of Beholders and Illithid monsters, and beating down Smaug bare handed?
Because that's just a standard adventuring day for his DnD counterparts.
Frodo has the one ring, which in your translation might be just a weird ring of invisibility, but in fact is the mightiest object on middle earth.
And he bears the artefacts curse, which is much more of superhero than to fly through the air shooting laserbeams out of whatever.
Translated to D&D:
If e.g Frodo could not resist the one rings daily urges, by passing the appropriate saves and ability checks, or if he choses willfully to give in, he could become a godlike being. Or maybe not him, but remember that Gandalf as well as Galadriel refused to take the one ring because they could not resist its promise of power.
