I Smell a Rat: Rune-Lined Hallway

[Anthony]

It depends a bit on some assumptions that are not clearly stated. A key thing is just how often someone can be affected by the runes. If you have to leave the area and come back to be affected again, you can sneak carefully down the passage. If it hits people every turn, you have to run through it, and the odds are the party winds up noisily trickling into the room with the Peshkali. Or worse, piling up at the door because something blocks the doorway.
