Synergies
Book of Virtues: Spawns an extra wisp and rerolls all of Isaac's wisps. All of the wisps will reroll into the same type of wisp.
Glitched Crown / (Tainted Isaac) 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.
- (Tainted Lost) Tainted Lost: Allows him to obtain items otherwise hardcoded to never naturally spawn for him.
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) Corrupted Data: Glitch items will disappear if rerolled.
Bugs
| (Bug) Bug! | When playing as (Tainted Isaac) Tainted Isaac and holding (Butter!) Butter!, the pedestal that Spindown Dice spawns on is considered a new pedestal generation, causing it to cycle to a different item and Spindown Dice will be fully charged if picked back up. |
