Takes Isaac to an abandoned and expanded version of Home, which has one copy of almost every item in the game. After taking an item, Isaac returns to the room he used Death Certificate in.
There are also several pickups and chests in the area. Picking them up/opening them will not cause Isaac to leave the area.
If a chest in the area contains an item, picking it up will cause Isaac to leave the area. This also applies to items created through use of pre-obtained items brought into the area, such as Eden's Soul or Mystery Gift.
Items that have not been unlocked will not show up in this unique location.
Items that are typically only granted under special circumstances like Dogma and Mom's Shovel are present.
The layout of the area is randomly generated, and items will show up in order of lowest ID number to highest (starting at items in the flash version and working up to Repentance items.
A new Death Certificate area is randomly generated on the next floor.
If more items are added to the game through modding, the area will expand to include them, ordered after the Repentance items. There is no way to flag an item as hidden, so items not intended by the mod creators to be normally obtainable may be found here as well.
On daily challenges, only Clicker and R Key will be missing.
C Section can be found in the Death Certificate area, despite not being in any item pools. This is one of the only ways to obtain the item.
Using Death Certificate while in the area that generates from using it consumes the item without doing anything.
Using this item multiple times in the same floor will always teleport to the same areas, without respawning the items that were taken or destroyed.
Since taking an item only destroys the other ones in the current room, you still have a lot of items available.
You can be softlocked by using Death Certificate while having already taken/destroyed all items that were in the area.
Using this item during the fight against The Beast resets the fight after Isaac leaves the special area.
If you are teleported to a Devil Room or an Angel Room, you will be teleported to the room you used Death Certificate in after taking a deal.
? Card: Mimics the effect of Death Certificate without consuming it.
Diplopia: Has no use inside of the Home area, as Isaac can only take 1 item. However, it can be used to duplicate the Death Certificate item, allowing Isaac to enter the area twice.
The Forgotten + Birthright: If timed correctly, switching from The Soul to The Forgotten can cancel the teleport out of the area, allowing for multiple items to be picked up. This can be done even if Birthright is not acquired before Death Certificate, as there is enough time to exit the room with The Soul and switch to The Forgotten after picking up Birthright.
Jacob and Esau: Both characters can take an item from any given room if they're lined up correctly and take them at the same time.
Schoolbag: Allows Isaac to hold another Activated item into the area along with Death Certificate.
Void / Abyss / Black Rune: Allows the consumption of items without forcing Isaac to leave the area.
Moving Box: Allows an additional 10 items to be taken without forcing Isaac to leave the area.
Metronome: Can invoke the effect of Death Certificate as normal, even if it is not unlocked.
Red Key: Using the Red Key in this area has a chance of spawning special rooms from Home. If Mom's bedroom is spawned and Isaac sleeps in the bed, the cutscene usually preceding the Dogma fight will play, but nothing will change.
Sacred Orb / NO! (doubled): The area will contain significantly fewer rooms and items to choose from, as they prevent items with low quality from appearing.
Using 0 - The Fool in this area crashes the game if no "starting room" is generated there.
Attempting to access this area again using Ventricle Razor crashes the game.
