Haemolacria

**Haemolacria** is an unlockable passive item added in *The Binding of Isaac: Afterbirth † (Booster Pack #4)*.

## Effects

* Tears are fired in an arc. Upon hitting the floor, an obstacle, or an enemy they burst into smaller tears in all directions.
	+ The number of burst tears is random between 6-11 and they have equal chance.
	+ The scattered tears deal random damage that is 50-83.33% of the main tear. On average, they deal 66% damage.
* Tears down: Tear Delay × 2 + 10
	+ The tear delay adjustment is applied after fire rate downs, before fire rate ups.
* 1.31~x damage multiplier.
* +1 damage and 1.5x damage multiplier.
* Range down: 0.8x range multiplier.
* The main tear has a roughly 1.71x size multiplier.

## Notes

* Higher shot speed lowers the arc of the main shot, whereas lower speed heightens it, resulting in a very minor change in effective range.
	+ The split tears are affected normally by shot speed.
* The tear falling speed stat is entirely ignored for both the main shot and the split tears.

## Synergies

* : Haemolacria has priority. +20 Tear Delay after Haemolacria tears down, instead of Brimstone tears down. The main tears burst into 4-7 brimstone beams instead of smaller tears. The beams deal 100% damage per tick.
	+ This does not apply to  Azazel/ Tainted Azazel's default brimstone beam, which is overwritten but with no special effects.
	+ If the powered-up version is acquired through another Brimstone or through , the 1.2x damage multiplier is overriden by Haemolacria's own 1.5x damage multiplier. The beams' width doubles.
	+ Brimstone + : The brimstone beams deal 100% damage regardless the charge. Chocolate Milk allows for rapid firing of Haemolacria tears, giving Isaac the ability to flood the room with Brimstone lasers.
	+ Brimstone + : The lasers coil the beams, which is purely visual, and Technology does not grant 1.5x damage multiplier.
	+ Dangerous when combined with
* /  The Forgotten /  Tainted Forgotten: Burst effect occurs on each enemy hit. It also increases the size of the club, similar to . The throw is unaffected and does not scatter blood tears.
	+ The Soul uses Haemolacria as normal.
* : Completely charged shots and their burst tears are larger and deal higher damage than normal. Chocolate Milk also allows low-damage Haemolacria shots to be fired rapidly.
	+ Increased tear delay.
* / : The main tears can split as they burst upon hitting an obstacle, or an enemy, but not upon hitting the floor. The split tears can burst, but burst tears from main tears do not split.
* : Main tears can split as they burst upon hitting the floor, an obstacle, or an enemy. The split tears can burst, but burst tears from main tears do not split.
	+ Haemolacria's x0.8 range multiplier does not stack with Cricket's Body's own x0.8 range multiplier.
* : Both the main tear and the burst tears can increase the damage bonus, but missing the burst tears won't reset it.
* : Haemolacria has priority. +10 Tear Delay after Haemolacria tears down, instead of Dr. Fetus tears down. The main tear is reminiscent of a bomb and scatters into 3-5 bombs that explode simultaneously. The split bombs deal half of Dr. Fetus' damage calculation based on the main tear's damage.
	+ Double Dr. Fetus: Isaac fires one additional Haemolacria tear, essentially a multi-shot effect, without stat change.
	+ Dr. Fetus + : Sad bombs from Haemolacria tears shoot 10 Haemolacria tears, which then scatters into bombs without Sad Bombs' property.
* : Tear delay is increased by 1/3 compared to either of the items on their own, but Isaac now fires Ipecac shots that release poisonous, high-damage but non-explosive split tears on impact.
	+ Haemolacria's x0.8 range multiplier does not stack with Ipecac's own x0.8 range multiplier. Can be dangerous when combined with .
* : Main tears can feed on other main tears or burst tears while burst tears cannot feed. The main tears will burst into 8 tears that have Haemolacria's burst effect upon impact or being fed enough. If they impact too soon after being fired or hit an enemy, they will burst into Haemolacria's burst tears. Lachryphagy's burst tears do not benefit from Haemolacria's synergies with other items, such as  or .
* : Fires 12 Haemolacria tears, all of which will burst.
* : Haemolacria tears fire while Mom's Knife is charging.
	+ Mom's Knife has priority. +10 Tear Delay, instead of Haemolacria tears down.
	+ Mom's Knife +  Lilith: Mom's Knife overrides.
* : Monstro's Lung has priority. Fire rate is reduced. Fires 8 Haemolacria tears, all of which will burst.
* : Range becomes extremely high, making Haemolacria tears follow Isaac for a long time before hitting the ground. Burst tears do not have a boomerang effect.
* : Effects combine to create large tears that bounce off each other and burst into smaller, standard tears that are not effected by Proptosis.
* : Haemolacria has priority. Fires arcing tears that release Technology lasers upon bursting. The lasers deal 100% Isaac's Damage.
	+ Double Technology: Isaac fires one additional Haemolacria tear, essentially a multi-shot effect.
* : Haemolacria has priority. The tears burst into 3-5 Tech X rings on impact. The sizes of the rings are various, but they deal 100% Isaac's Damage.
	+ Double Tech X: Isaac fires one additional Haemolacria tear, essentially a multi-shot effect.
* : Both Trisagion and Haemolacria fire at the same time, Haemolacria does not keep spectral tears despite its tears sprite change but the arced tear keeps piercing.
	+ Haemolacria becomes one big Trisagion beam that splits into more beams when it reaches its max range.

## Interactions

* Azazel: Haemolacria overrides Azazel's Brimstone.
* + //: Haemolacria's 1.5x damage multiplier stacks with these items' own 1.5x damage multipliers as expected.
* : C Section has priority. +4 Tear Delay, instead of Haemolacria tears down. Fetuses explode into a burst of tears when they hit the ground.
* : Epic Fetus has priority. +10 Tear Delay, instead of Haemolacria tears down.
* : At the base range, the main tear bounces once, releasing burst tears which do not bounce, then bursts normally. At a high range, the main tear can bounce multiple times.
* : Main tear retains all effects, but burst tears do not.
	+ The main tear has the damaging aura as well as the burst tears.
* **Haemolacria**: Additional copy of this item, such as from  / , grants +1 damage instead of normal stat changes.
* : The main tear can be a holy tear and bursts normally in addition to the light beam. Burst tears have an independent chance of being holy tears.
	+ The burst tears inherit the effect from the main tear. They do not have an independent chance.
* : Overridden by Haemolacria. Only stat changes apply.
	+ Works as expected. The kidney stone also bursts when it reaches its max range.
* : Overridden by Haemolacria, provides piercing.
* : Only the main tear will leave creep.
	+ Both main and burst tears spawn creep.
* : **Not recommended.** Unlike other similar items, Haemolacria's x0.8 range multiplier does stack with Number One's own x0.8 range multiplier, thus drastically reducing range.
* Piercing tears / Spectral tears: The main tear gains these effects, but the burst tears don't inherit them.
	+ Burst tears inherit these effects.
* : Stat changes applied as normal. The main tear gains the semi-piercing ability and may not burst when hitting a weaker enemy. Burst tears do not semi-pierce.
	+ Burst tears do semi-pierce.
* : Tears no longer arc, but will still burst when hitting an obstacle or stopping and falling to the ground. Burst tears do not bounce off of each other.
* : Split tears from thrown keys are normal tears.
* : If the main tear is a booger, it will get stuck and not burst on hitting an enemy. Split tears have an independent chance of being booger tears.
	+ The burst tears inherit the effect from the main tear. They do not have an independent chance.
* : Spirit Sword has priority. +10 Tear Delay, instead of Haemolacria tears down. The projectiles from the sword arc and burst.
* : Only main tears can be connected.
	+ Main tears and bursts can be connected via electricity.
* : The main tear follows the beam, but the burst spreads normally.

## Trivia

* Haemolacria is based on this Steam Workshop item by HiHowAreYou, originally known as Water Balloon.
* Haemolacria is a rare condition that causes people to produce tears that are composed of blood.
* When  Tainted ??? uses Haemolacria, the tears will be black instead of red. This is purely cosmetic, and is probably a reference to how stools containing dried blood are often black.
