OOC: Good thinking, @rredmond. Let's give everybody a Listen check to hear Dame Simonetta's warning. A reminder that Hobbets have improved listen (success on 5-6) as a racial ability in this system.
A Team: Kiplyn succeeds with a 6 and hears the Dame, loud and clear.
C Team (at -1 penalty because they are behind closed doors): Beppo and Carc both roll 6's and succeed. Of note, even though there is a deep chasm in this hallway, Dame Simonetta's voice is not echoing up from below; her voice can only be heard muffled through the doors. So to answer your question: Noh doesn't hear, but his bird alerts him (and Beppo can fill the others in on what he heard).
Black Pudding: fails with a roll of 4. Evil DM will leave it to the players' imagination, the best explanation for the failed Listen check: 1) it doesn't have ears, 2) it is too focused on its meal, 3) it is desensitized to the sound of screaming hobbets, 4) all of the above.
