Ho
It is quite possible that with a couple of lucky die rolls, I wind up with an artifact. Now, since the GM should never make any changes, how does that work with "Gygaxian" balance?
I actually saw this happen, more than 20 years ago, playing 1E. It was the Ring of Gaxx on a random Orc. There was a round table discussion of "could an Orc be carrying an artifact by chance alone?".
It ended poorly as low level characters are not designed to handle protecting powerful magic items. But I did see it in play! [while it's possible it was a DM error, it really has been > 20 years, I am pretty sure if it was an error it was a subtle one]
