This item is from the set of Dark Ranger items that comes from but for some reason its name is simply "Dark Ranger"

Shouldn't it be called something like "Dark Ranger Arrow" instead? It seems like maybe the item's full name wasn't put in properly whenever it was added to the site.

I think that's the actual name of the bow itself, some weapons do tend to be names?

Or not it could be a naming issue but I think it might just be intentional.

Possibly, it just seems kind of odd though based on the rest of the set.

I think it was released a while ago though, so I'm not sure if anyone asked about it back then or anything.
