White Plume Mountain - 1st Edition AD&D
White Plume Mountain is two things: a straight-up dungeon crawl, and a gigantic fetch quest. The players must enter the titular volcanic mountain and retrieve three magical weapons from an evil wizard who has made his lair inside. While the trident (named Wave) and the warhammer (named Whelm) are cool, we all wanted one thing: the +3, intelligent, chaotic neutral, soul-devouring greatsword Blackrazor. White Plume Mountain forced players to work together, and to succeed or fail as a group.
