Crystal Caste put out a special "d4". Why the quotes, you ask? Because the die has 12 sides. However, only 4 of them are numbered. These four sides are arranged in an elongated cube shape, with small, pyramid-like sides on the long ends of the cube, so small that gravity forces the cube to land on one of the bigger, numbered sides. Quite ingenious: Mabye not as random as a regular d4, but this freak show of dice rolls quite well, and looks damn spiffy, too.
