Nope, class specific uniques only drop for that class, just like class specific aspects. Gonna have to either kill them on your druid, get someone to carry you through runs, or get someone to give you a spare one.
One possible solution is to farm up cache’s from the tree or loot goblin bags on a high level character, then stash them and have your druid open them. Low chance of getting it, but you’ll be getting a ton of other gear at the same time.
