Might've thought that, but the Onion Knight is flagged Unique. You can't roll for it or acquire duplicates. Unless, maybe player stashed one in retainer/saddlebag, got another one and used that, and now stuck with one that can't be used or, evidently, discarded.

Oh. Different idea. Trying to use while /sitting down, or maybe otherwise emoting? I remember the inconvenience of being sat, but having to stand if I wanted to check my WT journal or hunt marks or the like.
