As far as whether or not the weapons would affect Ravine, that's ultimately up to you! They function by forcing the particles of energy that compose the gods to become superheated and basically shake apart. If that sounds like something that would have an effect on your character then feel free!

We are not sure what samandrine is? Generally, they would still be able to recognize her through her voice and physical form but if her appearance has changed drastically and she doesn't speak or cry out or anything while fighting them then it's possible that they wouldn't be able to identify her.
