I think that snowglobe is needed for Hook to absorb all the Darkness, but also maked the previous Dark Ones tangible. Merlin said, that only Nimue can help destroy the Darness now. She was the first Dark One, and it needs to killed at its source. Lol, so Christmas is coming? I'm pretty sure that wouldn't be how that works if Rumple was using it. Just a Darkness tracker and that's how Hook could tell that Emma would likely save him.

Chances are that the Merlin wand (The one the Apprentice had) can transfer all the Darkness into a single person  and the stuff you described.
