Added in Afterbirth †

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: Removed in Repentance Tear Delay × 2 + 10 / Added in Repentance Tear Delay × 2 + 11.
    • Added in Repentance The tear delay adjustment is applied after fire rate downs, before fire rate ups.
  • Increases damage by about 31%.
    • Added in Repentance +1 damage and 1.5x damage multiplier.
  • Added in Repentance Range down: 0.8x range 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 height stat is entirely ignored for both the main shot and the split tears.
  • The main tear has a roughly 1.71x size multiplier.

Synergies[]

  • Brimstone Brimstone: 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 Azazel/ Tainted Azazel Tainted Azazel's default brimstone beam.
    • Added in Repentance Double Brimstone: Grants +1 Damage, does not grant 1.2x damage multiplier. The beams' width doubles.
    • Brimstone + Chocolate Milk Chocolate Milk: 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.
    • Added in Repentance Brimstone + Technology Technology: The lasers coil the beams, which is purely visual, and Technology does not grant 1.5x damage multiplier.
  • Added in RepentanceBerserk! Berserk! / The Forgotten The Forgotten / Tainted Forgotten Tainted Forgotten: Burst effect occurs on each enemy hit. It also increases the size of the club, similar to Polyphemus Polyphemus. The throw is unaffected and does not scatter blood tears.
  • Chocolate Milk Chocolate Milk: 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.
    • Removed in Repentance Increased tear delay.
  • Compound Fracture Compound Fracture / The Parasite The Parasite: 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.
  • Cricket's Body Cricket's Body: 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.
  • Dead Eye Dead Eye: Both the main tear and the burst tears can increase the damage bonus, but missing the burst tears won't reset it.
  • Dr. Fetus Dr. Fetus: 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.
    • Added in Repentance Double Dr. Fetus: Isaac fires one additional Haemolacria tear, essentially a multi-shot effect, without stat change.
    • Dr. Fetus + Sad Bombs Sad Bombs: Sad bombs from Haemolacria tears shoot 10 Haemolacria tears, which then scatters into bombs without Sad Bombs' property.
  • Ipecac Ipecac: +10 Tear Delay after Haemolacria tears down, instead of Ipecac tears down. The main tears explode on impact and burst. The burst tears are poisonous and non-explosive and inherit the high damage from Ipecac.
  • Lachryphagy Lachryphagy: 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. Lachrypha's burst tears do not benefit from Haemolacria's synergies with other items, such as Brimstone Brimstone or Tech X Tech X.
  • Lead Pencil Lead Pencil: Fires 12 Haemolacria tears, all of which will burst.
  • Mom's Knife Mom's Knife: Haemolacria tears fire while Mom's Knife is charging.
    • Added in Repentance Mom's Knife has priority. +10 Tear Delay, instead of Haemolacria tears down.
    • Mom's Knife + Lilith Lilith: Mom's Knife overrides.
  • Monstro's Lung Monstro's Lung: Monstro's Lung has priority. +43 Tear Delay after Haemolacria tears down, instead of Monstro's Lung tears down. Fires 8 Haemolacria tears, all of which will burst.
  • My Reflection My Reflection: 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.
  • Technology Technology: Haemolacria has priority. Fires arcing tears that release Technology lasers upon bursting. The lasers deal 100% Isaac's Damage.
    • Added in Repentance Double Technology: Isaac fires one additional Haemolacria tear, essentially a multi-shot effect.
  • Tech X Tech X: 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.
    • Added in Repentance Double Tech X: Isaac fires one additional Haemolacria tear, essentially a multi-shot effect.
  • Trisagion Trisagion: 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.
    • Added in Repentance Haemolacria becomes one big Trisagion beam that splits into more beams when it reaches its max range.
