I held an ingot made from magical material, which was pretty much something I created from generating other ores through my body. There hadn't been any mines that we have encountered, aside from dropped items from the dungeon, which we also refine into ingots.
This ingot in specific is made out of mostly mithril with jewels infused with magical elements I had formed out of my body with a variety of skills, which I had compressed into ingots previously.
And then there were an assortment of other colorful ingots, all made out of dropped items which we melted and made into ingots instead. We cannot mine magical metals but the dropped items from the dungeons can be made into ingots anyways so we can forge new weapons and armor that are way better.
