Hmmmm...
Secret door or mystery mist hallway?
Sometimes I wish I wasn't so logical. If I wasn't, I wouldn't know that important and valuable things are usually at least as well guarded as this hallway full of LSD mist.
I take a moment to suggest that some Mage cast dispel magic on that mist filled hallway, then I inhale deeply, hold my breath, and run into the misty hallway, searching for doors, traps, and treasure.
You inhale deeply and quickly dart into the mists.
[17 + 5] You find no traps or treasure. However, you do find a door on the south side of the hallway, about thirty feet after the stairs (The corridor extends for only ten feet after that, if you're wondering).
Ah well. I poke my spear through the mist a few times from outside the mist room proper, to see if anything unusual happens.
Nothing unusual happens to the spear, which is good news for Javier.
Follow and double check after Javier for traps.
You follow Javier and double check for traps.You forgot to hold your breath, didn't you?
[FORTITUDE: 1] As you enter the mist-filled archway you are immediately seized with bowel-gripping horror. Gibbering to yourself in terror, you run screaming out of the mist, leaving a trail behind you.
Hold my breath and check the mist hallway for traps.
[17 + 5] The misty hallway contains no traps.
Malaken shall go through the recently-discovered secret door!
Someone has already looked through the secret door, so you decide to go down the corridor and see what's around the corner.
The hallway extends for forty feet before ending in a wooden door.
This makes me sad, I was expecting some minor chance of not dying horribly to some physical attacks.
Well pretty much all of the monsters in the tomb would have the strength to smush you flat even with stone-skin activated. If you're wondering, the monsters who can't smush you flat all have alternative attacks to brutally murder you.
It's the AD&D version, of course it's better. There's fewer saves.
It's not the lack of saves that makes it better. Any fool can put an insta-death poison in a hidden spiked pit. A true genius makes adventurers want to jump into the pit.
