4. Room With A Chest

This relatively large room is entirely empty, except for a chest slid back against the wall directly opposite the door. There is a pit trap under the chest, as you can see on the map. It can be detected as a secret door. The chest is not locked, but is the trigger for the pit trap; a cord goes through a hole in the bottom and attaches to the lid, so that either opening the lid or moving the chest will cause the pit to open. The rope prevents the chest from falling into the pit, and in fact as the pit automatically resets itself 1d4 turns after activation the chest will be pulled back into approximately the position it was in before the adventurers disturbed it. The pit drops victims 10 feet for 1d6 points of damage; a successful save vs. Death Ray (with Dexterity bonus applied) results in the character leaping away at the last moment and thus avoiding a fall. The chest is, of course, empty.
