What is your contender for worst magical item in the game?

I'm replaying again, doing a commit Shar Shadowheart origin run, and as I'm slogging through the Gauntlet of Shar, near Yurgir, there's a chest with Boots of Brilliance in them. Now look at these beauty. You get to restore ONE WHOLE bardic inspiration slot per long rest. Now, call me crazy, but getting this item, this late into the game (practically near the end of act 2), and absolutely nothing else attached to these boots is laughable. They had the audacity to make these boots blue in rarity too.

I can't think of any valid scenario where your Bard is wearing these boots. But maybe I'm wrong. Who knows.
