Effects[edit | edit source]

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 Blank Card and Placebo Placebo.
  • Jera can not be duplicated.
  • Mimics will not be duplicated.
  • A brown chest may be duplicated into a red chest or a mimic.
  • 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 Mom's Purse/Belly Button Belly Button or Smelter Smelter.
    • However, with "consumable" trinkets such as Store Credit Store CreditTrinket Store Credit icon.pngThe next store purchase is free. The trinket disappears on purchase. or Bag Lunch Bag LunchTrinket Bag Lunch icon.pngTaking damage has a small chance to destroy the trinket and spawn Lunch., it can be extremely powerful.
  • It is possible to duplicate shop pickups that have not been purchased yet.
  • With Car Battery Car Battery, it is possible to infinitely generate battery pickups from a single Lil' Battery.
  • In combination with a 48 Hour Energy and Paper Clip Paper ClipTrinket Paper Clip icon.pngGolden Chests can be opened without using a key., the initial golden chests on The Chest can be infinitely duplicated and opened.
  • In Greed Mode, if a battery appears in the shop and a 2 of Diamonds 2 of Diamonds2 of Diamonds Icon.pngDoubles your coins. If you have no coins, gives you 2 instead. 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.
