Essa porta no Túmulo dos Horrores tem sido tradicionalmente um - como a pergunta especula que provavelmente deveria ser, embora os detalhes exatos daquela porta variem em edição.
Dungeons e dragões avançados
Túmulo dos Horrores (1978) diz sobre essa porta:
Adamantite Door: Although it is marked secret, it is very evident; the marking is simply to make certain that its actual nature is known. It has permanent anti-magics on it, and there is no magical or physical way of forcing entry. There are 3 slots in the door at about waist height. If 3 sword blades are shoved simultaneously into the slots, the 1' thick panel will swing open. This is a one way door which cannot be prevented from closing in 5 rounds! (7)
(Alterações de todas as letras maiúsculas para negrito minhas).
Dungeons e dragões avançados, 2ª edição
Retornar ao Túmulo dos Horrores (1998) inclui:
During Return to the Tomb of Horrors the PCs venture into the adnd Tomb, a facsimile of which is included with the Return box set. The adventure expects the adnd-2e DM to update the original Tomb to the new edition; Return to the Tomb of Horrors—the adventure proper rather than its ancillary books—has more details on page 55, none changing this door.
Túmulo dos Horrores não era do meu conhecimento atualizado para esta edição.
Dungeons and Dragons 3.5
Túmulo dos Horrores (2005) diz que no final desse corredor os aventureiros veem isso:
A door forged of gleaming metallic alloy with massive reinforced hinges bars passage beyond this point. Three vertical slots mar the door’s surface at waist height. Each slot is about 1 inch wide and 3 inches long.
Isso é seguido por informações para o Dungeon Master:
The 1-foot-thick steel door (it’s too expensive for the demons to keep replacing adamantine doors) is suffused with a globe of invulnerability effect. (However, only the door, its hinges, and the stone around the hinges are so affected, allowing it to shed any spell of 4th or lesser level.) The effect cannot be brought down by a targeted dispel magic, but it can be suppressed for 1d4 rounds if the dispel check beats a DC of 22. If the door is removed from the stone that moors it through some determined engineering, it loses all magical abilities. The door is locked (DC 45 Open Lock check), but opens of its own accord if three sword blades are simultaneously shoved into the slots.
(Links mine.) Então segue outra nota para o Dungeon Master:
Once open, the door automatically swings closed 5 rounds later. In addition to the invulnerability effect, the door enjoys a magical hardness (which can be suppressed for 1d4 rounds as the invulnerability effect) that allows it to mash any metal less deformable than adamantine that someone may put in place to hold it open. A character trying to hold it open needs to make a DC 30 Strength check each round to hold it open. From inside (room 25), no slots or other obvious methods can get the door open again. (25)
Eu não li a novela do Greyhawk Classics Túmulo dos Horrores (2002 ) que foi lançado durante a era de Dungeons and Dragons, 3ª edição , então eu não sei se essa porta é descrita de outra forma nela.
Dungeons and Dragons, 4ª edição
Túmulo dos Horrores (2010) diz sobre essa porta:
Nothing! Building as it does on the 2nd Edition adventure Return to the Tomb of Horrors, the original tomb's layout is duplicated, but time has seen its guardians replaced and many of its traps defeated. Although the included map does designate the door as secret, sadly no special features of it are described. (See Tomb of Horrors on pages 100 and 154–5 for the scant details.)
Wikipedia 's Tumba dos Horrores entrada diz que uma porta mais direta da aventura original existe para a 4ª Edição , chamando-a de "atualização do módulo original para as regras da 4ª edição , escrita por Scott Fitzgerald Gray e [que foi] liberado para membros da RPGA como parte do programa DM Rewards. " Eu não tenho acesso a esta aventura.
Masmorras e Dragões, 5ª Edição
Como uma porta mais ou menos direta do original, este leitor concorda que o texto provavelmente está errado e que a porta deve impedir que aqueles que passam por ele retornem de onde vieram.
