I had an idea, and I'm still working out the details, but here's the general thing:
Artifact: Flesh Doll
This artifact was first created by Sorcerers, and remains used almost exclusively by them. Celestials have no use for them, and most Archangels and Demon Princes don't like the idea of their Soldiers having them, for different reasons. The Flesh Doll does not look like a doll at all; instead, it's a linked pair of bracelets, collars, or one of each. The first is worn by the user, and the second is slipped around a place on an empty vessel or vessel-substitute. There are two ways to get a vessel for the Flesh Doll. The guilt-free, but very difficult, way is to have it gifted by a Superior or construct your own out of Primordeal Clay. The easier way is to slip it around the wrist of a recently deceased animal or human corpse. Once in place, the bracelets allow a human to 'change vessels', or transfer their consciousness from their mortal body to the empty vessel.
There are significant restrictions compared to the vessel changes done by celestials. For one, it takes 5 Essence to activate the Flesh Doll. Second, the transfer of consciousness lasts for hours equal to the artifact's level...no more, and no less. The transfer cannot be terminated prematurely, and if either of the human's bodies die, either the possessed one, or the helpless human form left mindless, the human dies. Also, if the corpse-option is used, the body decays as normal when not possessed, and must soon be replaced. Despite these limitations, the Flesh Doll remains eagerly sought after by Sorcerers...they don't tend to have qualms about sacrificing the occassional bird or beast in order to gain the ability to spy on their enemies, or commit atrocities in animal form. Some myths of witches changing form, and werewolves, and other creatures, are surely inspired by these artifacts.
Cost: 5 points a level.
