(in Afterbirth † and Repentance)

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 (except in Repentance)8 tears (in Repentance)5 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[ | ]

  • Collectible 20 20 icon20/20 / Collectible The Inner Eye iconThe Inner Eye / Collectible Mutant Spider iconMutant 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.
  • (in Repentance)Collectible Akeldama iconAkeldama: 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.
  • Collectible Bob's Rotten Head iconBob's Rotten Head: The head act as a tear, dividing itself if enough time has passed and interacting with other tears. The five heads coming from the main head deal half damage. Feeding a head with another increases damage by the amount of damage Isaac has. If a tear is fed with a head, the tear will gain the head's damage.
  • (in Repentance)Collectible Book of Virtues iconBook of Virtues / (in Repentance)Collectible Jar of Wisps iconJar of Wisps: Wisps' tears can feed the Lachryphagy tears.
  • (in Repentance) Collectible Brimstone iconBrimstone: Brimstone's range is now limited, but comically large Lachryphagy tears will form at the end of the beam.
    • Character Azazel iconAzazel: Lachryphagy effectively leaves Azazel's brimstone unchanged given it already has limited range
  • Collectible Compound Fracture iconCompound Fracture: Bone tears split into a random spread of fractured tears and bone tears.
  • Collectible Cricket's Body iconCricket's Body / Collectible The Parasite iconThe Parasite: Fed tears split into 12 tears.
  • Collectible Dead Eye iconDead 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.
  • Collectible Euthanasia iconEuthanasia: Needle shots will allow the tears to burst at least twice.
  • Collectible Eye of Belial iconEye 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.
  • Collectible Evil Eye iconEvil Eye: can compound tears with Lachryphagy.
  • Collectible Haemolacria iconHaemolacria: 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.
    • (in Repentance) Haemolacria + Collectible Brimstone iconBrimstone / Collectible Tech X iconTech X / Collectible Technology iconTechnology: 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.
  • Collectible A Lump of Coal iconA 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.
  • Collectible Monstro's Lung iconMonstro's Lung / Collectible Lead Pencil iconLead Pencil: The tears clump together soon after firing, causing potentially up to 20x tear damage on a direct hit on an enemy.
  • Collectible My Reflection iconMy Reflection: Causes tears to float back towards Isaac and clump together with any tears they come along.
  • Pulse WormPulse Worm: The fluctuating hitboxes of the tears causes them to clump together at a faster rate.
  • (in Repentance)Collectible Revelation iconRevelation: The beam's range is now limited, but Lachryphagy tears will form at the end of it.
  • Collectible Sinus Infection iconSinus 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.
  • (in Repentance) Collectible Technology iconTechnology: Technology's range is now limited, but piercing Lachryphagy tears will form at the end of the beam.
  • Collectible Technology 2 iconTechnology 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.
  • (except in Repentance)Collectible Tractor Beam iconTractor Beam: All split tears will travel along the beam.
  • (in Repentance) Collectible Trisagion iconTrisagion: Trisagion tears will fade faster, but will constantly spit out more Lachryphagy tears while they are active.
