The Mage's Blade

Appearance
This greatsword appears to be forged from a solid piece of rough iron leaving small pits throughout the weapon. The pommel half of the weapon has been dipped into liquid mythril down to cover a third of the blade and turned so that uneven streams of mythril dripped along some of the length of the uncovered iron. The uncovered iron is blackened and grayed as though it were unfinished but it's edge is sharp regardless of the appearance. The pommel, handle, and guard are shaped into the likeness of an unspecificed dragon in flight with the tail running up the blade. The third of the blade covered in mythril has a narrowed portion that functions as another handle and the tail of the guard's dragon snakes around this second handle providing grip. When gripped by the second handle, the dragon becomes animated snarling curses at enemies and growling cheers upon successful strikes. When the Art is performed by it's wielder it bellows blue-silver fire in celebration. The dragon senses dead and wild magic areas and will wrap its body with it's wings or flap them as though in frantic flight to warn of each respectively.
