Sumptorium

**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 .
	+ 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 Heart and Rotten 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 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:

**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: Gold Hearts, Eternal Hearts, Rotten Hearts, Red Hearts, then the rightmost Soul Hearts, Black Hearts, 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

* : Gives the clots homing shots.
* : Doubles the clots' size and damage.
* : Increases the clots' fire rate.
* : Each use of Glowing Hourglass that does not move Isaac to a different room than the one he is currently in (such as the starting room of a new floor) will duplicate the clots. (This is possibly a bug)
* : Turns each clot into a penny.
* : Makes the clots deal 6 contact damage.
* : Spawns a controllable Ludo tear for each clot.
	+ + : Each Ludo tear's damage is based off of the distance from its corresponding clot.

## Interactions

* : For Tainted Eve, 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. Has no effect for other characters.
* : Cannot be used to duplicate clots.
* : 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.
* : Clots' tears will be redirected to Isaac instead of returning back to them.
* : 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.
* : Clots' tears will be fired from Isaac instead, and will stay within the tractor beam.

## Interactions with  Tainted Eve

* : 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.
* : 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.
* : 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.
