If a shadow has a long ranged weapon like the fire rod or upcoming bow and arrow but no sword it should try to keep a distance and line up with the player instead of running at them. Think of the bow and arrow enemies from ALttP if that helps paint a picture of what I’m talking about. I think it would make shadows much more interesting and easier to use in dungeons since with a sword they are very dangerous but without they are near helpless.
Alternatively a dedicated enemy that does this would also be cool.
