Recharge: 1 seconds
- Holding down the fire button will create blood clot familiars every two seconds and drain half a heart.
- Blood clot familiars mimic Tainted Eve's movement, firing, and tear effects.
- The familiars have health and will be destroyed if they take enough damage.
- Each type of heart generates a different type of blood clot:
- Red Hearts: A red familiar with tears that deal 33% of Tainted Eve's damage.
- Soul Hearts: A blue hush-like familiar with tears that deal 33% of Tainted Eve's damage.
- Black Hearts: A black devil-like familiar with tears that deal 40% of Tainted Eve's damage and have a effect.
- Eternal Hearts: A white familiar with tears that deal 50% of Tainted Eve's damage.
- Golden Hearts: A golden familiar with tears that deal 33% of Tainted Eve's damage and have a effect.
- Bone Hearts: A skeletal familiar with tears that deal 33% of Tainted Eve's damage and have a effect.
- Rotten Heart: A green familiar with tears that deal 33% of Tainted Eve's damage.
- Upon activation, Sumptorium destroys any remaining blood clots and heals Tainted Eve for the same type of hearts that were used to generate them.
- If every remaining clot is killed and Tainted Eve's has only half a heart left, she is granted a -like effect and begins to use Sumportium as a weapon that functions similar to for the rest of the room.
- The effect is also triggered if Tainted Eve's summons a blood clot while having no others and is left with half a heart. The summoned blood clot will use a small Mom's Knife for the rest of the room.
