So, I was exploring The Coppermind when I read through the Lerasium page. In it, it states that if a Mistborn were to burn Lerasium, it would strengthen their Allomantic power. If a Misting were to do the same, would on top of being a full powered Mistborn, also have the one metal they already had powered up beyond a Lerasium Mistborn? Another idea I had, was what if someone had a Hemalurgic spike for a metal as well as being full power?
