Acts as any dice item except for Spindown Dice, and can be cycled through by pressing the drop key.
- Charge time varies based on the current dice, and updates when used.

The icon of the D infinity will change to resemble the corresponding dice while being held. Putting it back on a pedestal will change its icon back to normal.
When in possession of more than one active item with the Schoolbag, all dice must be cycled through before the other active item can be used.
- When playing as Tainted Isaac and holding D infinity as well as another active item via Schoolbag, if Schoolbag is replaced by another passive item in its slot while the other active item is held, D infinity will be dropped on the ground, reset to its original state. This could allow the player to use any dice item with only a 2-pip charge.

Book of Virtues: Spawns a normal wisp in addition to having an extra effect based on the current dice selected.

Car Battery: Activates 2 dice. The second activation dice cannot be predicted.
- The second activation dice is determined by the seed and never changes.
Void: When absorbed and Void is used, replicates the effect of a random dice item.
- Acts as a copy of one of the 10 dice D infinity can replicate. This dice is randomly chosen and does not change.
