[Thaumatology] Specialist Magic-Users

[Prince Charon]

Had a weird thought last night or early this morning, mostly about the Improviser, but it could fit some other sorts of Embodier (including Diabolocal 'Puppeteers,' though the wise would not trust them to do this): Assume an Embodier whose advantages are not much help for emergency healing (or not good for Healing Magics at all), but who needs to heal someone. If they have time to summon the right spirit, they could temporarily Embody it in the person in need of healing, and the spirit's own abilities could start healing the subject. Depending on the setting, this might be quite difficult, and could have a wide range of possible consequences, benefits, or both. An Embodier who specializes in Possession Healing (for lack of a better term) might have one or more specialized Summon rituals for the purpose, but the thought in my mind was just something an Improviser or other Embodier does when a better healer isn't available.

So, can you think of any barriers to this working, or potential consequences (apart from 'a demon or other hostile spirit starts using the subject's body') or benefits to this? Any other thoughts on it?

A related thought is that an Embodier might instead summon a spirit with healing abilities into a separate body, and have that being do the healing; I think that's how most Embodiers would handle the situation, but desperate times can lead to otherwise quite strange decisions.
