Well, using the burrowing owl form for a talisman is a private in-joke. I am not super attached to it - if you have a suggestion, I'm open to change on this one. I want to keep the triple chain of brass, gold and iron.
Also, as I understand it, iron won't hurt (to touch at least). The protection at least makes her no more vulnerable to it than a human.
It would no longer hurt her to handle iron, no, just being stabbed with the pointy end.
