Eerie Staircase
Eerie Staircase is the room just before the Tree House, in the Haunted Towers, from the game Luigi's Mansion: Dark Moon. It is a very long staircase, which is seperated into 3 sets of stairs, with torches at the end of each flight, and small landings between the stairs.
When entering the room for the first time, Harsh Possessor is seen floating up the stairs, cackling in a very scary fashion. It will then exit the room to the Tree House. Luigi must then go up the seemingly endless staircase.
Characteristics
Out of the 3 sets of stairs, only one will let Luigi pass: the other 2 will make him slide to the bottom, and down there, a ghost must be defeated. If the player chooses the correct path, the torch on that chair will lit with a red flame, while the other blue flames on that level will extinguish, serving as a hint to the right path. There is no way of distinguishing the real staircase of a level from the 2 other fakes. At the top is located a door leading to the Tree House.
