I imagine you'd have to do so for all of the spectres present (and given both how many people were taken and how large the Warehouse is, it's probably safe to say it's a lot). The more that get identified and subsequently vanish, the more the general cloud of fog will disappear, which might make it easier to find each one.

I don't want to guide anyone's counter-artifact idea, but in case anyone wants a jumping off point, an artifact that solidifies vapor may also work for this artifact (or it could be used in addition to the artifact mentioned above). Totally up to whoever wants to work on this case to figure out, however many want to take a crack at it. I just figured mentioning something that crossedmy mind would be better than not.
