Idk though hah. I know. If I were them, I would wait until she's sleep or whenever she takes it off (which she does) and then she's defeated.

I would think the pendant is protected against that with dark magic. So, it could only be taken with light magic: that's why Zelena wanted Emma powerless but she didn't know Regina was able to perform light magic as well.
