Recharge Time	1 seconds
Item Pool	None
Unlock Method	Defeat Delirium as Tainted Eve

Sumptorium is an activated item added in The Binding of Isaac: Repentance. It is available exclusively for Tainted Eve as her starting item.

Effects

• Holding down the fire button will create blood clot familiars every two seconds and drain half a heart. This is indicated by a red charge bar, similar to that of Maw of the Void.
  • Blood clot familiars mimic Tainted Eve's movement (including flight), firing, and tear effects.
    • Blood clot familiars will mimic many (all?) tear-altering items, such as Spirit Sword.
    • Holding down the swap button allows Tainted Eve to move independently from the blood clots.
  • The familiars have health and will be destroyed if they take enough damage. They are immune to hazards such as spikes and fire places.
    • They are also immune to all kinds of 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	Health	Damage	Tear effect
		3	35%	n/a
		4.5	35%	n/a
		3	43%	Dark Matter
		3	52%	Sacred Heart
		3	35%	Midas' Touch (scales with luck)
		3	35%	Compound Fracture
		1.5	35%	n/a

• 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, a red blood stream will appear on her for each excess blot clot. This provides a very brief opportunity to create a blood clot free of charge, without draining any health, after which the stream disappears.

Interactions

Note: While Sumptorium is technically unlockable, it does currently not appear in any item pools, making it unobtainable for any character other than Tainted Eve, not even with Spindown Dice, without using mods or the Debug Console.

• Box of Friends: Cannot be used to duplicate clots.
• Car Battery: No interaction.
• 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.
• My Reflection: Clots' tears will be redirected to Isaac instead of returning back to them.
• Void: Absorbing this item will consume all clots made earlier, but will not generate new clots.

• The Forgotten: Clots made by Sumptorium will have a bone club as well. 2 red clots and 1 bone clot can be made with each full bone heart.
  • The active character will create clots, leaving the other character's health intact.
  • Switching to The Soul can be used to create extra soul clots, and they will switch between the bone club and firing tears normally as well.
  • 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.
  • Clots created while having the boomerang attack charged will instantly swing their bone, then hold their bone club like The Forgotten does in the opposite direction until throwing their bone.
• 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.
• Keeper/ Tainted Keeper: Clots made by Sumptorium will be red, and can not be consumed after using Sumptorium, but the clots have triple/quadruple shot respectively. Sumptorium will drain half a coin heart which is not usually seen for these characters.
• Bethany/ 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.
• Jacob and Esau: Sumptorium will only affect the brother whom it was given. Both brothers will generate clots at the same pace if given to both, but will only consume the clots from the brother that used the item.
• Tainted Magdalene: Making clots drains Magdalene's health much quicker, and at 12 red hearts, it will only absorb most of the hearts due to the character's unique ability.
• Tainted Samson/ Berserk!: Clots made by Sumptorium will have a donkey jawbone while berserking too.
• Tainted Azazel: Clots made by Sumptorium will have an even thinner Brimstone attack, and will sneeze too.
• Lazarus/Revival Items: Clots will be retained after losing the extra life.
• The Lost/ Tainted Lost: Unable to create clots, rendering this item useless.
• Tainted Lazarus: Sumptorium will only start making clots depending on which version it was given. You can give Dead Tainted Lazarus's health to Tainted Lazarus after using Flip just after using Sumptorium.
• Tainted Eden: Clots made by Sumptorium are retained permanently after taking damage.

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.

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.
• This item is unavailable for any character except Tainted Eve.
  • Defeating Delirium as Tainted Eve "unlocks" the item. However, it is not in any item pools.
    • This item will work on any other character, but it can only be obtained after spawning it/giving it directly to yourself via the Debug Console.
• If the player obtains flight, the clots will hover instead of lay down on the floor.

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.
