Whenever I try to use the 50% Golden Hammer, it just says "Cannot be used on this item."
I've tried using it on several items that haven't been hammered, I've tried it on items that don't have nebulites, and I've tried it on an item that is just clean. However, it doesn't work. Every time it just says "Cannot be used on this item."
Does it have certain conditions for it to be used or something?
