Is it ok if you let me know about the names of those exotic ores?
I've literally got them listed as Exotic Ore 1 and 2 on the guide image. I like to leave some things up to devs for their worldbuilding. The icons are easily recoloured too, to better fit their vision. Here's a list of fantasy metals and their properties https://www.gmbinder.com/share/-MiKX6oEHFc5UOZkYatR
