"I wasn't going to place them, I was going to show them to Natalya, let her tell me how big a field she needed where, build the requested devices, and then let her have a professional technician install them while I made sure they didn't short the device out. I would only build the things and then consult.<br/><br/>As for the cold iron device, yes they can, though the first, which was the one you attacked me trying to get, could only do cold iron. I need mine to make adamantine, mythiral, mithril, titanium, and others besides. I can make others that NOT make it, but that isn't to say a clever mage or another outfitter wouldn't be able to add it later. Hence my offer to not build more. Strangely, I HAVE thought this through a bit."
