Binding of Isaac: Rebirth Wiki

(in Repentance)

Sumptorium is an unlockable activated item added in The Binding of Isaac: Repentance.

Effects[ | ]

  • When used by any character other than Character Tainted Eve iconTainted Eve, removes half a heart of health upon use and creates a Clot familiar.
    • Blood clot familiars mimic Isaac's movement (including flight), firing, and tear effects.
    • Blood clot familiars will mimic all tear-altering effects, such as Collectible Spirit Sword iconSpirit Sword.
    • Holding down the swap button allows Isaac to move independently from the blood clots.
      • The familiars have health and will be destroyed if they take enough damage. They start with a set amount of HP when spawned, and the health of Red HeartRed Heart and Rotten HeartRotten Heart Clots will slowly decay down to 1 HP over time, while the health of the other clot types decay down to 5 HP.
        • Their health decays at a rate of 1 HP per 2.5 seconds.
        • They are immune to hazards such as spikes, Fire PlaceFire Places, and lasers.
        • Enemies deal 1 point of contact and projectile damage to them when hit.
        • Isaac's BombBombs and Troll BombTroll Bombs deal 2 points of damage.
      • Draining health does not count as taking damage, so creating familiars will not trigger damage-activated effects.
  • Each type of heart generates a different type of blood clot:
Heart Appearance Health Damage Tear effect
Red Heart Sumptorium red familiar 15 35% n/a
Soul Heart Sumptorium soul familiar 22.5 35% n/a
Black Heart Sumptorium black familiar 15 43% Collectible Dark Matter iconDark Matter
Eternal Heart Sumptorium eternal familiar 15 52% Collectible Sacred Heart iconSacred Heart
Gold Heart Sumptorium golden familiar 15 35% Collectible Midas' Touch iconMidas' Touch (scales with luck)
Bone heart Sumptorium bone familiar 15 35% Collectible Compound Fracture iconCompound Fracture
Rotten Heart Sumptorium rotten familiar 7.5 35% n/a

For Character Tainted Eve iconTainted Eve only:

  • Passively, holding down the fire button will create blood clot familiars every two seconds and drain half a heart.
  • Upon activation, Sumptorium destroys any remaining blood clots and heals Tainted Eve for the same type of hearts that were used to generate them. The blood clots deal 3x Tainted Eve's damage to enemies they pass through as they return.
    • Should Tainted Eve have more blood clots than room in her health bar when doing this, all excess blood clots will drop next to her.
  • The charge time is only 1 second rather than 10 seconds.

Notes[ | ]

  • The type of heart drained first is decided by the following order: Gold HeartGold Hearts, Eternal HeartEternal Hearts, Rotten HeartRotten Hearts, Red HeartRed Hearts, then the rightmost Soul HeartSoul Hearts, Black HeartBlack Hearts, or Bone HeartBone Hearts.
  • Clots from a previous run will carry over during a RERUN.
  • Sumptorium can't spawn more than 64 clots at once.
    • This limit is shared with blue flies and blue spiders. If there are multiple flies, spiders and clots on the screen at the same time, the limit will be 32 for the clots and 32 for the flies/spiders.
  • Sumptorium cannot absorb more than 29 clots at once.
  • Activating Sumptorium does not restore Tainted Eve's health immediately, as it is not restored until the recalled blood clots return to Eve.
  • If Isaac obtains flight, the clots will hover instead of moving across the floor.

  • Collectible Box of Friends iconBox of Friends: Cannot be used to duplicate clots.
  • Collectible Car Battery iconCar Battery: Summons 2 clots instead of one for double the health cost. Not Recommended for Character Tainted Keeper iconTainted Keeper as it can instantly kill him.

  • Character Tainted Eden iconTainted Eden: Clots made by Sumptorium are retained after taking damage.
  • Character Tainted Forgotten iconTainted Forgotten: Clots made by Sumptorium have a club too, but they are commanded by Character Tainted Soul iconTainted Soul, making it the only way to attack while moving freely.
  • Collectible Tractor Beam iconTractor Beam: Clots' tears will be fired from Isaac instead, and will stay within the tractor beam.

Interactions with Character Tainted Eve iconTainted Eve[ | ]

  • Collectible Alabaster Box iconAlabaster Box: Sumptorium can create clots by using hearts inside the box. It prioritizes hearts inside the box instead of using Eve's soul or black hearts.
  • Lil ClotLil Clot: The clot spawned by this trinket is its own separate clot variant although it functions the same as the red one. As such, it cannot be absorbed by Sumptorium.
  • Collectible Maggy's Bow iconMaggy's Bow: Does not provide additional healing when absorbing clots.

Trivia[ | ]

  • A Sumptorium is a metal drinking straw used in the Roman Rite to receive the Blood of Christ in Holy Communion.
  • Even though Tainted Eve wields a Sumptorium-like weapon when left on half a heart and all blood clots are destroyed, this is not an effect given by the Sumptorium item itself and is a character-specific trait.
