Magnesium

Magnesium is a grey, flammable metal that can be obtained by using derrick on magnesium subsoil spots. It is very light and strong, but usually unsuitable for a building material due to it's flammability. It will catch fire when struck with a stone surface (mountains, Stone, Quartz, etc), but the flammability is reduced when in a large mass. Magnesium also catches fire when signaled which makes it usefull for turning ice into water or burning someones creation to ashes.
