It's a funny story how I got that bone spear. Some guy about 5 levels over me (I think he was level 51 while I was level 47) used it for a bet in the Al Kharid Duel Arena. I ate food, though, and ended up killing him.
He thought I cheated, even though he was eating some food himself. You wouldn't imagine how angry he was at me. He was constantly spamming me, telling me to give it back or he'd report me.
I don't think that ever worked out for him.
I think the best part was that the stupid spear is only 1000gp. That's like nothing. He had no reason to complain.
