I know it isnt necessarily a rare, but I bought a breath of the dead one day. It was my first doom arty I ever owned, well I went into fel to play around, and saw that it was insured, well a bud of mine had a pack of bears, and wanted to see how they fought together, when I was fighting them, some assclown came in and ganked me cause I was grey. He killed me, and when I died, he said, "hey its like doom, I just got an arty for killing you" I realized that the insurance from the previous owner did not hold, and I had just lost a 1m sword.. I have tried for months to get it back, but he says he lost it. That was by far my most expensive death..
