It doesn't get more old school than rolling a d6 to check for wandering monsters in a dungeon. In the early 1980s, rolling a "1" meant you were in for a fight. Back then, you could even acquire dice which replaced the "1" with a monstrous face: like the Flying Buffalo "Death Dice" (above left), or Lou Zocchi's Gamescience "Demon/Orc Dice" (right). But the very first dungeon delvers encountered wandering monsters when the die came up "6" -- the rule shifted to encounters resulting from a "1" around the time these two dice appeared. Read on for a bit more about dice in this tradition, and the change in the wandering monster rules that went along with them.
