# Talk:Spellbook of passwall
The effect of the spell known as 'passwall' is to make the caster ethereal and so able to pass through walls. I have not tested it in Gehennom or Sokoban, only in the Dungeons of Doom. I would guess that it would not work in Gehennom or Sokoban, but this is unknown as of yet. Also, I have not tested it in a shop. It is unknown how a shopkeeper would react to this spell. Also unknown is whether or not a monster has the ability to strike the caster. ItazuEstamaru 16:58, 14 August 2008 (UTC)
It works in Gehennom (In SLASHEM at least)
It doesn't work in Sokoban; the game says "The sokoban walls resist your ability". --Bluescreenofdeath (talk) 07:14, 19 February 2014 (UTC)
