(Added in Afterbirth) This item belongs to the Seraphim set. Collecting three items from this set will transform Isaac into an angel.

(???) ???, (Tainted ???) Tainted ???, (Dark Judas) Dark Judas, (Tainted Judas) Tainted Judas, and (Tainted Forgotten) Tainted Forgotten: Decreases the chances of useless red heart drops, which these characters can't pick up.
(Bethany) Bethany: Sacrifices potential healing for more charges. Usefulness depends on active item.
(Eve) Eve/ Whore of Babylon: Decreases the chance of useless red heart drops when trying to maintain the half a heart (full heart on Eve) of health required to keep Whore of Babylon's ability active.
(Keeper) Keeper/ (Tainted Keeper) Tainted Keeper: Nearly useless, since all hearts are converted into blue flies anyway. Only use is contributing to the Seraphim transformation.
(Tainted Bethany) Tainted Bethany: Sacrifices potential blood charges for more health. Overall, still a beneficial pickup.
(Tainted Magdalene) Tainted Magdalene: Due to the "in your face" gameplay of Tainted Maggy, soul hearts will not be as useful up until the later floors.
