Okay yeah thanks so far everyone. I was more of thinking along the lines of ideas for allomantic metals, what other people thought would be cool, than what there could be or possible combinations/alloys that haven't been explored yet.
So I recently re-read the Mistborn series and I've been wondering if there could possibly be any other Allomantic metals. If you have any theories or just ideas for metals that you think would be cool feel free to post them here.
