Haemolacria

Haemolacria is an unlockable passive item added in Booster Pack #4.

Effects

 * Tears are fired in an arc. Upon hitting the floor, an obstacle, or an enemy they burst into many smaller tears in all directions.
 * Increases tear delay by a static 35.
 * Increases damage by about 31%.
 * The scattered tears deal random damage that is around 50-80% of the main tear.

Interactions

 * : If a fire button is held down when a Haemolacria tear bursts, the burst tears will hover in place before being fired outwards.
 * / / : The visual effects on tears don't work, but the damage bonuses do.
 * Azazel: Haemolacria overrides Azazel's Brimstone.
 * : Isaac's tears shrink considerably, but otherwise function as expected: tears pierce enemies instead of bursting on contact. The visual effect is not maintained.
 * : Overrides Haemolacria, with increased damage and tear delay.
 * + : Isaac shoots Haemolacria tears, which spawn tear bombs, which explode and create more Haemolacria tears in a continuous chain. This can cause lagging, and may possibly crash the game. The chain may stop during some phase changes in boss fights like Mega Satan.
 * : The tear loses its ability to burst on hitting enemies, turning into an Eye of Belial tear instead.
 * This no longer happens as of Booster Pack 5; the tear bursts as normal.
 * : At base range, the main tear bounces once, releasing burst tears which do not bounce, then bursts normally. At high range, the main tear can bounce multiple times.
 * : The main tear has the damaging aura but burst tears do not.
 * + The Forgotten: The blood tears from the bone club have the damaging aura.
 * : Overridden by Haemolacria. Only stat changes apply.
 * : Overridden by Haemolacria.
 * : The large tear will shrink if an enemy dies on hit, reducing the damage of the burst tears.
 * : Tears will burst only when they hit the floor, not on walls or enemies.
 * : If the main tear is a booger, it will get stuck and not burst on hitting an enemy, dealing its heightened damage. Split tears have an independent chance of being booger tears.
 * : The main tear follows the beam, but the burst spreads normally.

Synergies

 * //: Multiple Haemolacria shots are fired simultaneously.
 * : The main tear splits if it hits the prism. Burst tears will only split if the main tear did not split.
 * : Significantly increased tear delay. Isaac fires a large arcing tear with the Brimstone symbol on it that fires several Brimstone beams in random directions upon bursting.
 * : Completely charged tears and their burst tears are larger and deal higher damage than normal. Chocolate Milk also allows low-damage Haemolacria tears to be fired rapidly.
 * Conjoined transformation: Fires 3 Haemolacria tears simultaneously.
 * /: Similar to Cricket's Body, tears will split, scattering massive amounts of smaller tears across the room. Hits on walls or the floor absorb most of the extra tears.
 * : A single tear can scatter massive amounts of smaller tears in a wide area regardless of what it hits.
 * : Both the main tear and the burst tears can increase the damage bonus, but missing the burst tears won't reset it.
 * : Significantly increased tear delay. Isaac fires a large arcing tear reminiscent of a bomb that scatters into 3-5 bombs that explode simultaneously.
 * : The fire rate penalty of Haemolacria applies after Eve's Mascara's, which means in most cases fire rate is lowered much less than expected, while damage is still doubled.
 * : The familiar fires additional Haemolacria tears.
 * The Forgotten: Several blood tears are scattered upon the bone club hitting an enemy. Also increases the size of the club, similar to . The throw is unaffected and does not scatter blood tears.
 * : The main tear can be a holy tear and bursts normally in addition to the light beam. Split tears have an independent chance of being holy tears.
 * : Fires a large explosive shot that releases more explosive shots in all directions upon bursting.
 * : Tears look like Hameolacria. They can be fed and will burst into 8 tears that have Haemolacria's burst effect upon hitting obstacles or enemies.
 * : Fires a barrage of Haemolacria tears, all of which will burst.
 * Keeper: Fires 3 Haemolacria tears simultaneously, with lower fire rate.
 * : Haemolacria works with minimal tear delay while Mom's Knife has to be charged.
 * Does not work with Lilith, Mom's Knife overrides Haemolacria.
 * : Fires a barrage of Haemolacria tears. Increases charging time considerably.
 * : Removes the arcing behavior of the tears, massively increasing airtime of both the main tear and the scattered ones.
 * : The large tear floats in the air before exploding, and the smaller burst tears can be knocked around.
 * : Large tear and burst tears do roughly double normal damage.
 * : Fires a ring of Haemolacria tears.
 * : The tears burst into 3-5 Tech X rings on impact.
 * : Fires arcing tears that release Technology lasers upon bursting.
 * : Enemies and objects will be pulled toward the Haemolacria shot, increasing accuracy.
 * : The ten tears fired upon taking damage will all burst.

Trivia

 * Haemolacria is based on this Steam Workshop item by HiHowAreYou, originally known as Water Balloon.
 * The item is a reference to the rare condition with the same name that causes people to produce tears that are composed of blood.
