Source passage
These orcs, however, do not rely upon a continual watch being kept; instead, they have a series of nearly invisible strings running across the entry passage, about II’ from the entrance. When any of these strings is tripped, a heavy, weighted net suspended from the ceiling will drop upon intruders, and metal pieces tied to it will create an alarm sound. (The trip strings will be spotted only if careful observation is asked for, each observer having a 1 in 6 chance of seeing the devices. The camouflaged net is 10’ wide and 18’ long, made of thick, tarred ropes, and will entrap the victim for 1-4 rounds. Meanwhile, orcs from area 14. will be there in 1 round....)
