Notes[edit | edit source]
- By dropping a card, rune, or pill in a room with no other pickups, then using D1, this item can function similarly to
Blank Card and
Placebo.
Jera can not be duplicated.
- Mimic Chests will not be duplicated.
- A normal Chest may be duplicated into a Red Chest or a Mimic Chest.
- Opened chests will be duplicated into an unopened copy.
- A duplicated trinket is mostly useless, as you cannot pick up two of the same trinket even with
Mom's Purse/
Belly Button or
Smelter.
- However, with "consumable" trinkets such as
Store Credit or
Bag Lunch, it can be extremely powerful.
- However, with "consumable" trinkets such as
- It is possible to duplicate shop pickups that have not been purchased yet.
- With
Car Battery, it is possible to infinitely generate Lil' Batteries from a single Lil' Battery.
- In combination with a 48 Hour Energy and
Paper Clip, the initial Locked Chests on
The Chest can be infinitely duplicated and opened.
- In Greed mode, if a Lil' Battery appears in the Shop and a
2 of Diamonds is acquired, infinite money can be gained by duplicating the Two of Diamonds.
In-game Footage[edit | edit source]
Trivia[edit | edit source]
- D1 is the only dice item that doesn't re-roll anything.
- As such, its description, in certain cases, can be ironic, as the outcome is entirely predictable if there's only one pickup. This makes sense because the dice only has one pip on each of its 6 sides.
