Rudisplorkium is a rare mineral found naturally within the 333rd layer of the Abyss. It is regular iron that is infused with the unholy and undead energies over untold centuries to give it a unique property. Any item that is made of Rudisplorkium is 1,000 times more expensive, and fills those that hold it a strange urge to cheat at all things (DC=15 Will save to resist). They usually accomplish this cheating by optimizing their side to the utmost advantage.
However, that is not the only property held by Rudisplorkium. Any time someone attempts to draw, wield, or use in any fashion the material may make a transformation. When used there is a 5% chance an item made of Rudisplorkium will instead turn into ORCUS.
