So I'm working on the Tinker's Construct aspect of Blightfall, and I've got my smeltery built and running smoothly, but I've hit a bit of a snag. Apparently I need casts to make tools, and to make casts I need gold. However, gold has a mining level of "soft metal", and according to the stats on the wiki, the easiest material to get that has that stat is iron (apparently stone tools got nerfed in TC). This wouldn't be a problem, if not for the fact that Blightfall doesn't let you make Vanilla iron tools, only TC iron tools... which can't make without first making casts. I'm sure you can see how this would be a problem. Help?
