Mnimiron

Mnimiron is one of the natural metals of the thirty Arthosian metals. After it is cast and quenched, it seems to "remember" what shape it was originally cast in. If it is dented, the dent will pop itself back out, and usually do it very quickly. This property makes it ideal for armor, particularly helmets, as well as shields. However, over time it will become very brittle, which can become dangerous.
