Yeah, this seems only relevant if the DM is really stingy with magical items so players don’t have anything better to attune to. Usually I think this is a horrible idea, but I could see a campaign where you only get really weird not super powerful magical items and having to make them work. It probably wouldn’t be fun, but I bet there’s a few items out there it’d work for, though this isn’t one. This one is just boring and not useful.
