Tomb of Horrors

S1 Tomb of Horrors, the 1978 TSR module Gary Gygax's notorious killer dungeon began as the official D&D tournament at Origins I and was published by TSR in 1978. It is the adventure people mean when they talk about traps that punish carelessness, and it still divides tables between those who love it and those who never forgave it. The 1978 release pairs the module with a 20-page illustration booklet of pictures to show the players. Make sure that booklet is present, because a copy without it is incomplete and loses much of what makes this module special.
