On a more general note, it is clearly possible to get magical items. However, such things are not sold in actual shops. Cheaper items may be from street vendors, more expensive items would have to be tracked down to individual visiting merchants, or acquired through guilds, contacts, or even a faction or institution that makes them. Or you could have something made, but you don't really have time for that. The point is that most magic items cost the same as outfitting a squad of armoured knights, or buying a small naval vessel. You just don't get enough people doing it to develop any kind of passing trade. People look for you because they know what they want

I'm happy with junk or magical curio shops, but no descriptions of dedicated retail space please.
