Okay, new version, same old link.
I removed some of v004's Skulking races, since they seemed to be clogging up the civilization count.
I added a lot of new metals. Crucible steel now augments flux steel. Crucible steel can be produced with pig iron, iron, raw clear glass, clay and fuel. To my knowledge, this is more historically accurate anyways. You have option to create either flux steel or crucible steel, whichever is easier based on your location. To be realistic, flux steel should actually produce a different kind of steel than crucible steel, but whatever.
Besides iron steel, you can now produce elemental steels by using x-chalcum. Each can be produced with either flux or crucible. They maintain the properties from the raw metals, Blaze Steel is sharper, Rock Steel is heavier, Cloud Steel is lighter and Ocean Steel is prettier (higher value). Note that you will still need iron to produce elemental steels.
And finally, I've created Novachalcum, a combination of the 4 elemental metals. I still couldn't really decide what Novachalcum should be like, but I remembered that one time I modded in tungsten carbide and it was utterly too powerful, so I decided to use the same stats for Novachalcum. Novachalcum should be difficult to produce in great quantity, I'm hoping that the traders don't ruin it by bringing lots of meltables to your doorstep. The production of Novachalcum is reductive, combining 4 bars of the elemental metals will result in 2 bars of novachalcum.
I've also added a few of new kinds of wood. I haven't been able to actually find any in the world, but they are in the raws for you. White Oak should be good for creating wooden weapons, like staffs and nunchucks, Blade Bough is sharp like obsidian, Ironwood has the same properties as iron, but is not a metal and cannot be melted or forged, Ebony, Boxwood and Calamander are valuable woods, on par with metal.
