The Twin Spear

[Ironhawk]

I'm hosting a game where each nation starts in possession of several artifacts. But when I get around to assigning the Twin Spears to their respective nations all I keep getting are duplicates of the blood-based spear. Obviously this is because they are both named the same. But the #additem map modding command only seems to allow names to be used? How do I access the death-based spear??
