In the cold winter somewhere in Siberia an old wizard came up with a small thing to pass the time. He had hear of Russian Roulette but felt that was a little bit... messy and unfortunate. So he took a six shooter and then enchanted it. The magical item was enchanted so it would automatically gather enough magic to create a single magic bullet every day and could hold a maximum of 5 bullets worth of magic at a time. Then he had to code a few more rules to make sure the magic item couldn't be used for anything outside of Russian Roulette... Including a homing feature of sorts so the bullet could only hit and would always hit the person who fired it, the same person cant shoot the gun more than once in a row, and that it could sense the amount of people playing the game and make enough bullets for everyone minus one. The mode of transformation could be changed in several different ways, but after enough Vodka fueled enchantment nights he couldn't be bothered with adding a switch or something... They'd just have to get a mage to switch the mode or something... or figure out what mode it was on. Having no one to play it with the old Wizard just shipped it off to... somewhere. Some magic shop, curio collector, or... somewhere really since he just used a teleportation spell while drunk.
