In our last D&D session, I was playing as a simulacrum of my PC that was sent by the BBEG after my PC had been captured. About halfway through the session, the party noticed I was reluctant to use my spells and was more afraid of damage than normal. The Paladin suspected I might be under the influence of some spell, so he offered to use Cleansing Touch. I figured the simulacrum would assume this functioned like greater restoration, so he willingly accepted the offer.
The DM and I weren't sure what should happen in this situation. My first inclination was nothing would happen because the simulacrum itself is a creature with no spells affecting it. However, it also seems valid that the spell Simulacrum is animating-"affecting"-the simulacrum (creature).
What are your interpretations?
Edit: I did some additional research on the question and I think I found some more information that might be useful.
There are some great responses on Reddit to address the "multiple spells problem" mentioned by @Someone_Evil. So I believe that part of the question can be addressed by the DM asking for the Paladin to be a bit more specific on what he is trying to remove. I'll update this further as I do more research.
