Exploring The Dungeon: The Secret Corridor
The partially open secret door leads you to a long, narrow corridor. You can only walk down it single file. It is about 180 feet long, and contains three traps.
1: Classic pit trap, but, just beyond it, is another pit trap much better concealed.
2: Thin tripwire a foot above the floor that triggers the release of a nauseating gas.
3: 50 feet of magically greasy floor.
The last 10 feet of this corridor widen to 10X10. There is a door on the right side.
