From what I've found online, it looks like it may not be possible to add homebrew nonmagical weapons. I could not, however, find information that was more recent that 2020, nor do I know the homebrew system well enough to imagine whatever workarounds folks may have come up with (e.g., making a magic item that isn't magical).
I am running a Campaign in D&D Beyond and I would like to make several homebrew weapons that any player in the campaign can add to their character sheet and use. At least some of my players aren't going to spend the time to add these weapons themselves if they require customization, but they will add them to their character sheets if they can follow the normal path for adding an item.
Is there a method, short of editing their character sheets myself, where I can make custom weapons available within a Campaign?
