The steel of this eerie weapon is worked in a pattern that writhes and swirls slowly when examined closely. The blade emits a milky hue that seems to rise from the surface and swirl, like mist or smoke. The weapon is a +3 longsword with the ghost touch quality. Additionally, any creature slain by the sword cannot be raised or animated as an undead creature, though they may be raised or resurrected normally. Even creatures slain by the sword, resurrected, and then again slain by another means cannot be turned into undead creatures.
