Synergies

 * /: 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 number by jumping to a higher ID, which is restricted by regular means of the dice.
 * + Butter!: The pedestal that Spindown Dice spawns on is considered a new pedestal generation, which means said pedestal not only has an alternate option that isn't Spindown Dice, but Spindown Dice also fully recharges upon use. This means that you are capable of obtaining any item in the game with a lower item ID than the one you started with.
 * Allows Tainted Lost to obtain items otherwise hardcoded to never naturally spawn for him.

Interactions

 * All future rerolls turn into the item that is 2 less than the previous ID. While this can work in your favor to get chains further down the ID list, it also makes it impossible to get even numbered IDs from odd numbered items and vice versa, and takes away a lot of potential items for you to reroll into.
 * Disappears upon being rerolled, as its internal ID number is 1.
 * / Corrupted Data: Glitch items will disappear if rerolled.
