OOC:
Just for clarity: none of you see any pressure plates. The floor ere simply too fragile and collapsed under Bellows wight.
Elrond guess that similar could happen with the floor investigating (he automatically passed investigation, though it took some time)
I've put few more marker to the map, Now you know that "corridor W" is save, have found a floor that collapsed in corridor N but don't see (yet) anything suspicious further. You know that that a part of floor is suspicious in the hall, it required a touch distance to make floor investigation as due to the dust the floor looks no different.
Angius, please explain where are you moving - where are you checking the ground with your hand made pole
OOC:
Anyone have suggestions how to make it simpler to explain where are you going? I''m used to do it real time with player controlled tokens
