Secret Chamber is an Action-Reaction card from the first edition of Intrigue. It allows you to move cards between your hand and the top of your deck when an Attack is played. This helps to defend against deck inspection attacks such as Spy and Swindler, by allowing you to choose what card the Attack finds, and against handsize attacks by helping ensure that you have cards in hand that you want to discard. It does not directly protect against Cursers. When played as an action, it lets you discard cards for , which lets you get some value out of Curses and Victory cards.

- When someone else plays an Attack card, you may reveal Secret Chamber from your hand. If you do, first you draw 2 cards, then you put any 2 cards from your hand on top of your deck (in any order).
- The cards you put back do not have to be the ones you drew. You can put Secret Chamber itself on top of your deck; it's still in your hand when you reveal it.
- Revealing Secret Chamber happens prior to resolving what an Attack does to you. For example, if another player plays Thief, you can reveal Secret Chamber, draw 2 cards, put 2 back, and then you resolve getting hit by the Thief.

 Other Rules clarifications
- You may reveal the same Secret Chamber multiple times when reacting to an Attack; for example, in response to an attack, you could reveal Secret Chamber, draw a Moat and a Copper off the top of your deck, put back two coppers, reveal the Moat to be unaffected by the attack, and then reveal Secret Chamber again to put either the Moat or the Secret Chamber back on top of your deck.
- Revealing the Secret Chamber alone does NOT prevent the attack from affecting you. You can reveal Secret Chamber even in response to an attack that does not affect the top of your deck, like Witch.
- You must reveal the Secret Chamber as soon as the Attack is played, but before any text on it is resolved. So if your opponent plays Minion or Pirate Ship, you must finish drawing cards and then putting cards back on top before your opponent makes their choice for which action on attack card to take.
