Spindown Dice

Spindown Dice is an unlockable activated item added in The Binding of Isaac: Repentance.

Effects

• Rerolls all pedestal items in a room by subtracting their internal ID number by one until a valid item is rolled. This effect occurs per item and is independent of any other items in the room.
  • Unlockable items will be skipped if they are not unlocked.

Notes

• Hidden items will always be skipped, including:
  • Recall
  • Hold
  • The passive version of Damocles created by usage of Damocles (the one with item ID "656").
  • The passive version of The Book of Belial created by Birthright effect of Judas / Black Judas (the one with item ID "59").
• Items created by using Spindown Dice are not considered "normally generated" and can be encountered again in their normal pools if they were not picked up.
• Spindown Dice ignores all effects that prevent certain items from spawning, such as through item quality thresholds (e.g. Sacred Orb), Item Tags or other effects such as from NO!.
  • This makes the item especially valuable for Tainted Lost, as many helpful items cannot naturally spawn for him otherwise.
• If used in a Challenge or Daily Challenge, Spindown Dice will skip over items with the "nochallenge" and "nodaily" tags, respectively.

• The following is a list of rerolls notable because the item rerolled into is otherwise difficult to obtain:
  • The Black Bean → Fate (only rarely dropped from Locked Chests)
  • Bomb Bag → A Pony (only dropped by Headless Horseman)
  • Boom! → A Dollar (only dropped from Slot Machines)
  • Butter Bean → Head of Krampus (only dropped by Krampus)
  • Crooked Penny → Wait What? (only found when it replaces Butter Bean in item pools)
  • Halo of Flies → Skatole (only dropped from Shell Games)
  • Guppy's Paw → A Lump of Coal (only dropped by Krampus or from Mystery Gift)

  • Sacred Heart → White Pony (only dropped by Conquest)
  • Sausage → Dad's Note (only found in the special Mausoleum / Gehenna II boss room)
    • Doing so is pointless as Dad's Note cannot be rerolled further by any means, even though the next spindown ID would be Strawman.
  • Spelunker Hat → The Small Rock (only found by destroying Tinted Rocks or playing Crane Games)
  • Spirit of the Night → Crystal Ball (only dropped from Fortune Telling Machines)
  • Spirit Shackles → Redemption (only dropped from Confessionals or Sacrifice Rooms after taking a devil deal)

• The following items' ID are continuous, which are not recommended to re-roll:
  • Mom's Lipstick → Mom's Underwear → The Belt → Wooden Spoon → Rotten Meat → Breakfast → Dessert → Dinner → Lunch

Synergies

• Book of Virtues: Spawns a random wisp in the middle ring and rerolls all of Isaac's wisps into the type that was just spawned. Due to some wisps having unique behaviors, Isaac can end up with more or less wisps in a given ring than expected.
• Glitched Crown / Isaac with Birthright / Tainted Isaac: Rerolling a cycling item will reduce the ID number of the displayed item by 1 and randomize all other options. This may allow Isaac to acquire items with large ID numbers by jumping to a higher ID.

Interactions

• Car Battery: All future rerolls turn into the item that is 2 less than the previous ID.
• The Sad Onion: Disappears upon being rerolled, as its internal ID number is 1.
• TMTRAINER / Corrupted Data: Glitch items will disappear if rerolled.

Trivia

• A spindown die is a type of die used as a life counter for Magic: The Gathering or for various other uses across card and board games. It is a D20 with the numbers laid out in a sequential pattern, to allow for the face-up number to be changed easily when a player's life goes up or down.
• The item's color scheme matches the D8 die included in The Binding of Isaac: Four Souls card game, which is used as a spindown die to keep track of an enemy's health.
• Spindown Dice is the only dice item that cannot be copied by the D infinity.
  • It is arguable that Spindown Dice is not necessarily a dice item, since its effect does not involve random generation.
• Spindown Dice itself will be rerolled into Anima Sola, while Hypercoagulation rerolls into it.
• Using Spindown Dice on Smart Fly rerolls into Clear Rune, which is the only Repentance added item to reroll from a Rebirth one. This is due to the item taking up a previously unused item id.
• Two items are impossible to obtain with Spindown Dice:
  • Mom's Ring, as it has the highest ID of all items (without mods taking a higher number, etc).
  • Strawman, due to Dad's Note having immunity to being rerolled.
• Defeating Delirium as most tainted characters will unlock an item that is similar to their gameplay characteristic. However, Tainted Isaac's passive ability to have multiple items cycle on an item pedestal (Glitched Crown) is unlocked through defeating The Beast instead.
