Had an amusing struggle of a session last night that's worth relating. My players (aasimar paladin, tiefling cleric, half-elf rogue, gnome witch) have been plowing their way through the Nessian Spiral, getting deeper and deeper and deeper.
Well.
Last night they made it into area F29 - Hall of Toil. The resident Behir spotted them and issued it's command. "Drop your weapons, pick up those tools and start mining."
Nervous tension
I called for a set of Will saves for the suggestion, mass.
The paladin rolled... a 1.
The cleric rolled... a 1.
The rogue rolled... a 1.
The witch succeeded.
Jaw drop
Okay, um, hmmm. Roll for initiative, please.
The witch produced... 6.
The Behir produced... 7.
Deep sigh
The Behir moved up, took an attack at the witch and missed. The witch took a 5ft, located a wand of invisibility and used it. The Behir, being not terribly bright sniffed around and (not having scent) failed a Perception check. It spent the next couple rounds looking around, trying to figure out what was going on.
We dropped out of per-round and the witch located a wand of break enchantment and failed to meet the CL four times. He then ran away and I called the session so I could do research and think.
We packed up our stuff. We discussed things in general. Then the players remembered that the paladin had magic circle against evil up. Um. Immunity. Hello. Since the Spiral was built by The Thrice Damned House, I figure they're evil casters, and since the suggestion, mass was actually part of the environment (the Neutral Behir just activates it), the immunity should have taken place.
Given the nature of the encounter, we'll be re-running it next time.
But seriously. Three natural ones?!?
