Black greatsword, swathed in noxious fumes

Black greatsword, swathed in noxious fumes <caustic> <red glow>

Description:	The sword is coal-black, its long blade almost crude in appearance. The surface of the narrow, slightly curved blade looks like it was charred in intense heat. But a closer look reveals fine, blood-red gravures covering the whole surface of this malicious weapon. Despite its looks, the blade is sharp - very, very sharp. The gravures seep acid and the sword hungers for blood. The darksteel blade ends to a hilt and pommel crafted out of demon's bone. It contains a tale; Wrath of the Tyrant is Demigod Az'anzyl's feared blade. As a manifestation of pure evil, Az'anzyl, the Bloodspirit of ancient worlds, required weapon worthy of his malice. The blade he forged with his bare fists, the hilt and pommel were made of a demon's bone - for demons are more common than angels in the depths where Az'anzyl emerged from. The blade is powerfully enchanted; blood runes encircle the blade that bleeds acid.
