White Plume Mountain is an adventure module for the Advanced Dungeons & Dragons fantasy role-playing game, written by Lawrence Schick and published by TSR in 1979. The 16-page adventure bears the code “S2” (“S” for “special”). The adventure is a dungeon crawl where the players’ characters are hired to retrieve three “notorious” magical weapons, each possessing its own intelligence. The adventure contains art by Erol Otus, and a cover by Jeff Dee. A sequel, Return to White Plume Mountain, was published in 1999, and an updated version conforming to v3.5 rules was released online in 2005. The original was again updated for the 5th edition in 2017 as the fourth part of Tales from the Yawning Portal.
