Unlock Method	Defeat Delirium as Tainted Eve

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

Effects

• When used by any character other than Tainted 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 Spirit Sword.
  • Holding down the swap button allows Isaac's to move independently from the blood clots.
    • The familiars have health and will be destroyed if they take enough damage. They start with 15 HP when spawned and slowly decay down to 1 HP (5 HP for non-red hearts) over time, similarly to Minisaacs from Giant Cell.
      • They are immune to hazards such as spikes, fire places, and lasers.
      • Enemies deal 1 point of contact and projectile damage to them when hit.
      • Isaac's bombs and troll 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	Damage	Tear effect
		35%	n/a
		35%	n/a
		43%	Dark Matter
		52%	Sacred Heart
		35%	Midas' Touch (scales with luck)
		35%	Compound Fracture
		35%	n/a

For Tainted 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: Golden Hearts, Eternal Hearts, Rotten Hearts, Red Hearts, then the rightmost Soul, Black, or Bone 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.
• Clots scale with Isaac's size.

Synergies

• Baby-Bender: Gives the clots homing shots.
• BFFS!: Doubles the clots' size and damage.
• Forgotten Lullaby: Increases the clots' fire rate.
• Sacrificial Altar: Turns each clot into a penny.
• Spin to Win: Makes the clots deal 6 contact damage.
• The Ludovico Technique: Spawns a controllable Ludo tear for each clot.
  • The Ludovico Technique + A Lump of Coal: Each Ludo tear's damage is based off of the distance from its corresponding clot.

Interactions

• Book of Virtues: It will create red wisps for every clot consumed, and they will disappear if she starts creating clots again. Soul charges cannot be used to create wisps.
• Box of Friends: Cannot be used to duplicate clots.
• Car Battery: Summons 2 clots instead of one for double the health cost. Not Recommended for Tainted Keeper as it can instantly kill him.
• The Forgotten: In order to stop clots from moving while playing as The Forgotten, it is needed to hold down Left CTRL/RT while switching to The Soul, and vice-versa.
• Keeper/ Tainted Keeper: Coin hearts count as Red hearts.
• Lazarus/Revival Items: Clots will be retained after losing the extra life.
• The Lost/ Tainted Lost: Sumptorium kills The Lost and Tainted Lost immediately upon use.
• My Reflection: Clots' tears will be redirected to Isaac instead of returning back to them.
• Strawman: Clots will follow Strawman instead of Isaac if they were spawned in a previous room.
• Tainted Eden: Clots made by Sumptorium are retained after taking damage.
• Tainted Forgotten: Clots made by Sumptorium have a club too, but they are commanded by Tainted Soul, making it the only way to attack while moving freely.
• Tractor Beam: Clots' tears will be fired from Isaac instead, and will stay within the tractor beam.
• Void: Absorbing this item will consume all clots made earlier, but will not generate new clots.

Interactions with Tainted Eve

• Alabaster 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 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.
• Maggy'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.
