Elemental Sword

Description
The Elemental Sword has the shape resembling both fire and ice. Unlike the Fiery Dragon Sword, Icy Dragon Sword or Fiery Gladius, however, the "fire" and "ice" are not animated and are part of the sword itself. Also, since it has no fixed elemental sword hilt, that means it can be upgraded with another hilt.
