Spiked Corridor // Torture Pit
Enchantment — Room // Enchantment — Room
Rulings (19)
While on the battlefield, a Room's characteristics are a combination of the characteristics of its unlocked doors. For example, if Bottomless Pool // Locker Room is on the battlefield with both doors unlocked, its names are Bottomless Pool and Locker Room, its mana value is 6, it's a Room Enchantment, and it has the abilities in each door's text box.
The additional 2 damage is dealt by the same source as the original source of damage. The additional damage isn't dealt by Torture Pit unless Torture Pit is the original source of damage.
While in any zone other than the stack or the battlefield, a Room card's characteristics are a combination of its two doors. For example, Bottomless Pool // Locker Room has a mana value of 6 while it's in your library. If an effect allows you to search your library for a card with mana value 4 or less, you can't find Bottomless Pool // Locker Room.
