How can I get a spooky looking staff as a Hexblade that will actually hit things? It's for the aesthetic, it isn't some broken combination of weapon properties or anything like that. To my knowledge you can't do anything with this that you wouldn't otherwise be able to do with the other mentioned weapon buffs?
