Elemental Sword

Description
The Elemental Sword is a rare sword that has a blade with a top half that resembles ice and the bottom half, fire. Unlike the Fiery Dragon Sword, Icy Dragon Sword or Fiery Gladius, however, the "fire" and "ice" are not animated. Also, since it has no fixed elemental sword hilt, this means it can be upgraded with another hilt.

Location
This sword is an extremely rare drop from various locked chests and monsters in some areas of Nightfall and GW:EN, but is a somewhat less rare find from the dungeon reward chests in GW:EN.
