Divine Crystal of Flames

A rare crystal which can only be found in a handful of places in Raktehelm. The crystal appears to contain the essence of flames, and is also known as "The Everlasting Flame". This mysterious crystal has the ability to raise its own heat in response to the strength of its user's fighting spirit. Even the most skilled technicians have trouble handling it, so there are only a few weapons in the world which use this crystal.
