So I’m going to write this character who grew up for a major part of her young life in a fighting pit without an arm, she mainly relied on the “that girl without an arm can’t be a threat” and then beat their butts when their backs were turned, and I’d like her to be able to wield a sword and shield, and I’m trying to work out the logistics of that, like would it make sense for her to have a piece of wood attached to her stump to better support the shield and stuff, or am I wrong?

So I’ve kept this in my askbox for a while because I’m not sure how to respond to it. I give prompts and some writing advice on this blog.  This question is way outside my limited expertise. I’ll throw it out there in case someone has an answer.
