At my table, I guess there is one superstition: if one former player, lets call him Jake, ever touches or borrows dice; forever cold they will go. So far, it's held up. He borrowed a D20 of mine without me knowing it. It was a reliable, if not spectacular roller, about 60-70% good rolls. He got a hold of it, and I was lucky to get over a 14. Nice of the rest of the group to let me know he used it BEFORE I had to tangle with the Ogre patrol....For the sake of my dice, I'm glad he's gone, but as a player and friend, I do miss him.
