Copper poisoning

An idea that could make some of the new copper utilities more useful, maybe rarely when hit by a copper sword it could give a short period of the poison effect. Maybe critical hits could make it more likely, and armor makes it less, and maybe even an enchantment to increase the chances and lifespan of the poison I remember developers saying that they would like to add more tools and armor, but for them to differ more than just stats. I think this would be great for overall combat so people don’t just throw out their copper swords or tools when they craft them. Another idea: maybe if they get oxidized variants, they do less damage but increases the chances of copper poisoning
