Crystalline Sword

Description
The Crystalline Sword is arguably one of the coolest looking swords in the game, very rare and very sought after. The blade is made of a piece of translucent, thin, yet very hard and razor-sharp 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 (both locked chests and quest reward chests) in the Fissure of Woe. They have also been found as random drops in the Crystal Desert.

A long sword with the Crystalline Sword skin used to be given as quest reward after completing The Prize Moa Bird, but it has since been removed to prevent people scamming with it. It was replaced with a regular Long Sword skinned item. They could also be found in the Frozen chest in Dreadnought's Drift, but this particular method was nerfed in an update, to increase rarity.

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).
