Dungeons and Dragons Clue

Who Killed the Archmage? Was it Tordek in the Dragon`s Lair with the Flaming Battle Axe? Or Mialee in the Dungeon with the Staff of Power? A group of heroic adventurers has been called to the Archmage`s castle. But one of those heroes isn`t who he or she appears to be. One of the heroes is a doppelganger, a monster that can look like anyone! Now, in the grand tradition of Clue, the six suspects must determine which one of them is the doppelganger.
