Which means she needs to think about that charm. Would it even work on her? She is immune to all attempts to alter her emotional state. She could let it through, she supposes. But if she doesn't know it is what they say it is, that's maybe not the best idea. Maybe she could shape her defences to only let in Hysh-aspected magic? That would let it through if Ishaza were honest, and Hysh isn't shaped right to do something terrible to her mind.
Actually, does she want the horror of battle to pass faster? Should it? She did just kill a man.
Okay, it's been a few seconds of waiting in visible hesitation, she can think about that in more detail later, now she needs to respond.
"I think the charm would work. But- I have reason to think I will not scar, and what does not scar is right to feel for a time, if not to live in. Would it wash even that away?"
