Dragon Quest: Death Palace

One of many boardgames loosely based off Enix's Dragon Quest RPG videogame series (known as Dragon Warrior in the US).

This one plays most like The Warlock of Firetop Mountain or TSR's Dungeon!. Go into the various rooms, take a random event card, battle monsters, get treasures, and try to get the medallions that will grant access to the Treasure Room.
