1. You'Ve Got That Sinking Feeling

Important Note: The secret door from this room to room 2 is only accessible after the trap is activated. This twenty-foot-square room looks quite empty. If anyone enters the main 20' x 20' part of the room, there is a 1-2 on 1d6 chance (per person) that the trap will activate: Suddenly the floor begins to drop swiftly downward! Only characters near the 10' x 10' entranceway have a chance of avoiding the sinking floor; a successful save vs. Death Ray with Dexterity added will allow the character to jump back into the entranceway. No damage is inflicted by the falling floor, which descends 40 feet straight downward. What is not obvious is that the floor of room 2, below, also sinks when the floor of this room falls. The secret door shown on the map can only be found and accessed after the floor has gone down. A lever in room 2 can be used to restore both floors to their proper altitude. Finally, when the trap is tripped a small bell in room 3 rings. It is not a loud bell and will not be heard in other rooms normally; it serves to notify the occupant of room 3 that there are visitors in this room. The ogre in room 3 will be quick to pay the victims a visit (2d4 rounds), usually choosing to approach from the corridor so as to come up behind anyone who managed to stay in the passageway.
