The Phantom Blade
The Phantom Blade is a ghostly white blade which is cursed by Rogues everywhere. The sword can prevent Rogues from stealthing away, even with Vanish. The sword is notable for being one of the few one-handed weapons which show across the back (as is normal for two-handed weapons) at rest, instead at the sides, which is normal for one-handed weapons.
Source
The Phantom Blade is crafted by Blacksmiths with a skill level of 245. Prior to 2.0.3, it also required the Weaponsmith specialty.
The plans are taught by the Weaponsmithing trainer.
Background
This section concerns content exclusive to the Warcraft RPG, and thus is not necessarily canon.
During the last war, the Lich King outfitted some of his incorporeal undead warriors with special armor, making them difficult to deal with. In response, human craftsmen developed the phantom blade. These longswords are a translucent white color, and seem to disappear almost entirely in sunlight.MM&M 119
