Retrieves the Tainted Forgotten's body automatically, even from a distance.

Tainted Forgotten will deal ~4-6 times Isaac's damage to enemies that collide with it while it's returning to the Soul.
Notes
This item is not in any item pool and is set to be hidden from appearing in any normal scenario. The only way to obtain it is by picking up Birthright as Tainted Forgotten which will give Tainted Forgotten the item in the consumable slot.
It can, however, activate when using Metronome. This does nothing with most characters, however it will return Tainted Forgotten's body to him if it is activated.
Re-rolling Birthright via D4, D100 or similar items will not remove Recall from the consumable slot.
The item cannot be used while the Soul is holding the body or the body is traveling after it has been thrown. Trying to use it will not waste its charge.
Obtaining Recall on any other character has no effect.
