Crystalline Sword

Description
The Crystalline Sword is one of the more unique-looking swords in the game. It is very rare, and very sought after. Perfect versions are among the most highly prized items available in Guild Wars, and can sell for literally millions of gold pieces on auction. The blade is made of a piece of thin, translucent crystal.

Location
Crystalline Swords are extremely rare; many players will never see one of these weapons. They occasionally drop from the chest in the Hall of Heroes, as well as chests (only quest reward chests) in the Fissure of Woe, the Underworld and Sorrow's Furnace.

Crystalline Swords do not drop from any monster in the game.

A long sword with the Crystalline Sword skin is also given as a reward after completing the Pre-Searing quest The Prize Moa Bird.

Dye
Applying dye to this sword affects the hilt (the gold part of the sword in the image). It also seems to make the color of the dye appear a little brighter or off-tint (such as a yellow being a bright, slightly green color).
