One thing I did with my Lilitu was, when I was cleaning her, I trimmed the metal tab attached to her feet away so that it was just under her feet. I then filed it back so that it was like a pin sticking from her feet. I then drilled a hole into the resin base I was using (it will probably work best with resin bases, not sure about standard bases or inserts) and effectively pinned her that way. Now you would have to put a fair bit of effort into getting her from the base.
