Transfiguring Spirits?

[immortalfrieza]

Ambition adds the Ghost Hunter Profession and with it, the ability to capture spirits. I haven't done it myself yet but apparently you can then use the Display case from World Adventures to Transfigure spirits into a urn and thus a ghost sim. However, there's really no information about how this mechanic works or what the results might be available that I can find other than that certain types of spirit will create a ghost with certain traits.
