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.
	+ Hidden items  will always be skipped, including:
		- The passive version of  created by usage of Damocles (the one with item ID "`656`").
		- The passive version of  created by  effect of  Judas /  Dark Judas (the one with item ID "`59`").

## Notes

* 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. ), Item Tags or other effects such as from .
	+ 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.

## Synergies

* : 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.
* /  Isaac with  /  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

* : All future rerolls turn into the item that is 2 less than the previous ID.
* : Disappears upon being rerolled, as its internal ID number is 1.
* /  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 dice to keep track of an enemy's health.
* Spindown Dice is the only dice item that cannot be copied by the .
* Spindown Dice itself will be rerolled into , while  rerolls into it.
* Using Spindown Dice on  rerolls into , 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:
	+ , as it has the highest ID of all items (without mods taking a higher number, etc).
	+ , due to  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 () is unlocked through defeating The Beast instead.
