I'm assuming it's that your raiding party are the people you do direct action with, and having a seamstress among you is super useful and important because they can not only create and mend clothes and other useful items like blankets and tents and banners, but in a real bind they could potentially sew up a wound, too!
I’m very much out of touch with most popular shows and games and such lol
Having said that, I looked it up, and if you're asking seriously and not just making a reference that's gone over my head, I think the answer could be any really, depending on the person and what other skills they have.
