    • The attack can be released only when fully charged.
    • Each tear deals 100% Isaac's Damage.
    • Each tear has a random size multiplier between 0.9x to 1.33x, but there is no effect on damage.
  • Tears down: Removed in RepentanceTear Delay × 4.3 / Added in Repentance Fire Rate ÷ 4.3 (roughly 0.23x).

Notes[]

  • Each tear has independant chance to have Tear Effects.
  • Added in Repentance Multi-shot effects such as 20/20 20/20 or Keeper Keeper adds 2.4 tears to the barrage per tear they normally grant. The resulting amount is rounded, and is capped at 50.

Synergies[]

  • 20/20 20/20 / The Inner Eye The Inner Eye / Mutant Spider Mutant Spider:
    • Removed in Repentance Adds 2, 5 or 7 tears to the barrage respectively. For the latter two, greatly slows down the charge.
      • 20/20 + The Inner Eye + The Inner Eye: 10 extra tears.
      • 20/20 + Mutant Spider: 14 extra tears.
      • The Inner Eye + Mutant Spider: 14 extra tears.
      • All three: 19 extra tears.
    • Added in Repentance Adds multi-shot effect they normally grant (see Notes section).
      • Without any other multi-shot effect, the barrage size becomes 16/19/21 respectively.
  • Added in RepentanceAlmond Milk Almond Milk / Added in RepentanceSoy Milk Soy Milk: Fires automatically upon reaching full charge.
  • Anti-Gravity Anti-Gravity: Hover effect is overidden, but tear delay down still applies, which greatly reduces the charge time.
  • Blood Clot Blood Clot: All tears are larger, with increased damage (as opposed to every 2nd tear like Blood Clot alone).
    • Added in Afterbirth † Tears have a 50% chance to be Blood Clot tears.
  • Added in AfterbirthBrimstone Brimstone: Brimstone has priority. Does not apply Monstro's Lung's tears down. Fires 3-5 additional beams in random directions around Isaac. This effect also applies to Azazel Azazel and Added in Repentance Tainted Azazel Tainted Azazel's versions of Brimstone.
    • Brimstone + Added in RepentanceEye Sore Eye Sore: Overrides this synergy with a chance to shoot 1-3 additional beams in random directions.
  • Chocolate Milk Chocolate Milk:
    • Removed in Repentance Reduces Isaac's tear delay by 20%, and each tear from Monstro's Lung is a charged Chocolate Milk shot, massively increasing fire rate and damage.
      • This does not apply to Lilith Lilith's Incubus; picking up Chocolate Milk will significantly reduce damage and increase charge time.
    • Added in Repentance The tear damage and the barrage size scale with charge amount. At 50% charge, the tear damage is 100%, the barrage size reaches 100% and is capped there. At 100% charge, the tear damage is 200%.
        • This makes damage per second drop to 80%.
  • Added in RepentanceEye Sore Eye Sore: Adds a chance to fire 1-3 additional barrages in random directions.
  • Added in AfterbirthDr. Fetus Dr. Fetus: Monstro's Lung has priority. Does not apply Dr. Fetus' tears down. Fires 6 bombs which detonate simultaneously.
    • Multi-shot effects add 1 bomb to the barrage, up to 21 bombs.
  • Added in AfterbirthEpic Fetus Epic Fetus: Epic Fetus has priority. Does not apply Monstro's Lung's tears down. 2-4 extra cursors rotate around the main cursor before the missiles land.
  • Added in Afterbirth †Flat Stone Flat Stone: All tears bounce simultaneously; the effective range is greatly increased.
  • Added in Afterbirth †Haemolacria Haemolacria: Monstro's Lung has priority. Applies +43 Tear Delay after Haemolacria tears down, instead of Monstro's Lung tears down. The barrage size is reduced to 4/7 (roughly 0.57), tears of which all burst.
    • The barrage size is 8 without any multi-shot effect. The resulting amount is rounded, and is capped at 29.
  • Ipecac Ipecac: Fires Ipecac tears, with no increase in charge time.
    • Added in Repentance Applies Ipecac's tears down.
  • Added in RepentanceTechnology Technology: Does not apply Monstro's Lung's tears down. Grants a charged shot, fires 12 lasers in 30° spead that arc 3-4 times. A laser can hit an enemy multiple times between their arcings.
      • This is equivalent of applying Monstro's Lung's tears down and its charge time, without actually altering tear delay.
    • Multi-shot effects add 12 lasers to the barrage, up to 128 lasers total.
    • Technology + Mysterious Liquid Mysterious Liquid: The lasers leave creep each time they arc, resulting in a massive amount of creep.
    • Technology + Proptosis Proptosis: The 6x damage is recovered each time they arc, nearly nullifying the distance penalty.
  • Added in AfterbirthTech X Tech X: Fires 3-5 extra rings in 30° spead. Extra rings deal from 50% to 100% damage of the main ring.
    • Additional copy of Monstro's Lung adds 3-5 more rings.

    • Removed in Repentance Charging an attack spawns spiders in rapid succession.
    • Added in Repentance Spawns spiders upon firing, not charging. The amount of spiders spawned is dependent on luck.
  • Monstro's Lung: Additional copies of this item, such as from Added in AfterbirthDiplopia Diplopia / Added in Afterbirth †Crooked Penny Crooked Penny, add Removed in Repentance 10/Added in Repentance 12 tears to the barrage.
    • This effects is equivalent of adding Removed in Repentance 4/Added in Repentance 5 multi-shot effects. The items which have priority over Monstro's Lung or override it (e.g. Brimstone Brimstone/Added in RepentanceC Section C Section) benefit from this multi-shot effect.
  • My Reflection My Reflection: Tears stay in the air much longer and consistently, allowing better reach and more focused blasts before the tears returning to Isaac.
  • Added in AfterbirthTractor Beam Tractor Beam: All the tears follow the beam at different heights without spreading out, making it much easier for multiple tears to hit a target.
