Added in Afterbirth †

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

Effects[]

  • Isaac's tears decelerate as they travel. Upon stopping or hitting an obstacle, they burst into Removed in Repentance8 tears Added in Repentance5 to 8 tears, depending on tear size, in all directions.
    • Hitting an enemy will not cause them to burst.
  • Tears can be fired into other tears to feed them, increasing their damage and the damage of the burst tears.
    • If one tear is fed 5 other tears, it will immediately burst.
    • The tears will have their damage added together, with the first consumed tear giving additional damage.
    • Tears in the burst will deal half the damage the main tear would have.
    • This also applies to Familiar tears.
  • Tear bursting can also happen from sheer shot size. With sufficiently high damage or several tear-size increasing items, the tears will burst almost immediately after firing.

Notes[]

  • Certain items that cause tears to split and feed each other, when combined, can cause the resulting tear to become so large that the game will crash. Use caution when using Lachryphagy with splitting tears.

Synergies[]

  • 20/20 20/20 / The Inner Eye The Inner Eye / Mutant Spider Mutant Spider: Tears tend to clump together soon after firing for high damage shots. It may take more than 5 tears in total to cause a burst.
  • Added in RepentanceAkeldama Akeldama: Akeldama tears can feed and be fed by the Lachryphagy tears. Fed Akeldama tears will gain increased damage but will not burst, and will cap at 5 tears fed each.
  • Added in RepentanceBook of Virtues Book of Virtues / Added in RepentanceJar of Wisps Jar of Wisps: Wisps' tears can feed the Lachryphagy tears.
  • Compound Fracture Compound Fracture: Bone tears split into a random spread of fractured tears and bone tears.
  • Cricket's Body Cricket's Body / The Parasite The Parasite: Fed tears split into 12 tears.
  • Dead Eye Dead Eye Firing into the floating tear won't reset the multiplier as long as that tear doesn't hit a wall. The burst tears will never reset the multiplier.
  • Euthanasia Euthanasia: Needle shots will allow the tears to burst at least twice.
  • Eye of Belial Eye of Belial: Tear burst retains Eye of Belial's effect, greatly increasing the effectiveness of the tear burst due to the piercing, spectral, and increased tear damage. By proxy, piercing, spectral, and continuum tears all improve the value of Lachyphagy.
  • Evil Eye Evil Eye: can compound tears with Lachryphagy.
  • Haemolacria Haemolacria: Tears look like Haemolacria. They can be fed and will burst into 8 tears that have Haemolacria's burst effect upon hitting obstacles or enemies.
    • Added in Repentance Haemolacria + Brimstone Brimstone / Tech X Tech X / Technology Technology: The tears behave like Lachryphagy tears. On hitting enemies, they always burst into respective Lachryphagy-synergized lasers (if available), but on hitting a wall or an obstacle, slower-moving shots burst into normal shots and faster ones into lasers.
  • Ipecac Ipecac: Lachryphagy tears will burst into ipecac shots and explode. The Ipecac tear burst will travel like a normal tear instead of an arc.
  • A Lump of Coal A Lump of Coal: Tears continually grow in size without being fed other tears, but they will still only deal bonus damage based strictly on how far they travel. Burst tears will still grow in size and damage as they travel.
  • Monstro's Lung Monstro's Lung / Lead Pencil Lead Pencil: The tears clump together soon after firing, causing potentially up to 20x tear damage on a direct hit on an enemy.
  • My Reflection My Reflection: causes tears to float back towards Isaac and clump together with any tears they come along.
  • Pulse Worm Pulse Worm: The fluctuating hitboxes of the tears causes them to clump together at a faster rate.
  • Added in RepentanceRevelation Revelation: The revelation beam will have reduced range, but spawns a stream of red Lachryphagy tears.
  • Sinus Infection Sinus Infection: Boogers will always burst into more boogers, though some of the boogers may incorrectly appear to be normal tears. When a booger sticks to an enemy, it will burst into 8 boogers which have a high chance of sticking again to the same enemy.
  • Technology 2 Technology 2: Significantly shortens the range of the laser. A Lachryphagy tear spawns at the end of the laser every tick, rapidly feeding off of each other and bursting when standing still.
  • Removed in RepentanceTractor Beam Tractor Beam: All split tears will travel along the beam.
