Elemental Sword

Description
One of the rarest swords in the game, 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.

Location
It has been reported that this sword drops rarely from chests in the Realm of Torment, Hall of Heroes and the Desolation.
