This sounds like intended gameplay, doesn’t it? In early access, none of the items with triggered effects had those effects end if the item was removed. You could turn your entire party invisible by passing around a single magic ring. If that hasn’t been resolved with launch, I really don’t see Larian fixing what you call an exploit (and they presumably call a feature).
Those exploits don't work anymore, because we reported them in early access and they got fixed. You can't pass around the sword of justice buff anymore.
