Monstro's Lung is a passive item.

Effect[edit | edit source]

  • Grants a charged shot that fires 14 tears in the same fashion as Monstro.
    • The attack can be released only when fully charged.
    • Tears down: Delay * 4.3.
    • Each tear has a random size multiplier between 0.9x to 1.33x, but there is no effect on damage.

Synergies[edit | edit source]

  • 15►Anti-Gravity Anti-Gravity: Tear delay down, which is greatly more effective due to Monstro's Lung's tear delay formula.
  • 15►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 Afterbirth 15►Brimstone Brimstone: Fires 3-5 additional Brimstone lasers in random directions around Isaac. It does not increase the charge time. This effect also applies to Azazel's version of Brimstone.
  • 15►Chocolate Milk Chocolate Milk: 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's Incubus; picking up Chocolate Milk will significantly reduce damage and increase charge time.
  • Added in Afterbirth 15►Dr. Fetus Dr. Fetus: Isaac spits multiple bombs but must charge to fire. Bombs detonate simultaneously.
  • Added in Afterbirth †15►Flat Stone Flat Stone: All tears bounce simultaneously; the effective range is greatly increased.
  • 15►Ipecac Ipecac: Isaac spews multiple Ipecac tears, with no increase in charge time.
    • Added in Repentance Charge time is greatly increased.
  • Added in Afterbirth 15►Mom's Knife Mom's Knife: Fires an additional cluster of 3-5 knives when at maximum charge, each dealing 2x tear damage.
  • Removed in Afterbirth † 15►Mom's Wig Mom's Wig: All the spiders will spawn instantly while charging his shot.
  • Added in Afterbirth15►Tractor 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.

Interactions[edit | edit source]

  • 15►20/20 20/20 / 15►The Inner Eye The Inner Eye / 15►Mutant Spider Mutant Spider: Adds 2, 5 or 7 tears to the barrage respectively.
    • 20/20 + 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.
  • 15►Chemical Peel Chemical Peel: Overridden by Monstro's Lung.
    • Added in Afterbirth † Tears have a 50% chance to be Chemical Peel tears.
  • 15►Cursed Eye Cursed Eye: Overridden by Monstro's Lung.
  • Added in Afterbirth 15►Epic Fetus Epic Fetus: Launches 3-5 cursors that rotate around each other before the missiles land.
  • Added in Afterbirth15►Epiphora Epiphora: No effect. Tears stat is increased properly but firing cancels the effect.
  • Removed in Afterbirth † Added in Afterbirth15►Kidney Stone Kidney Stone: If Monstro's Lung is picked up while Kidney Stone is ready to fire, charge time for Monstro's Lung will be significantly decreased.
    • Added in Afterbirth † Only stat effects from Kidney Stone apply.
  • 15►Loki's Horns Loki's Horns/15►Mom's Eye Mom's Eye: Isaac will still fire single tears in the other direction(s).
  • Added in Afterbirth 15►The Ludovico Technique The Ludovico Technique: Tear becomes a cluster of variably sized tears spread over a small area. The tears move at the same speed when controlled but constantly move around each other.
  • Added in Afterbirth15►Marked Marked: Only stat effects from Marked apply.
  • Monstro's Lung: Additional copies of the Lung add 10 tears to the barrage.
  • 15►My Reflection My Reflection: Tears stay in the air much longer and consistently, allowing better reach and more focused blasts before they are back.
  • 15►Strange Attractor Strange Attractor: Due to the high concentration of tears enemies will be pulled into Isaac at great force, in certain cases enough force to pull enemies through rocks.
  • Added in Afterbirth15►Tech X Tech X: Fires a group of laser rings with size dependent on how long they were charged, with increased charge time.
  • 15►Technology Technology: If picked up after Technology, Monstro's Lung has no effect. Technology will override Monstro's Lung with a very low tear shot.
    • Added in Afterbirth Charge effect is removed and fire rate returned to normal. Extra lasers will be shot in random directions around Isaac while firing.
    • Added in RepentanceRather than tears, zigzagging laser segments are fired in a spread pattern.
  • Added in Afterbirth15►The Wiz The Wiz: 7-8 tears are fired at each diagonal direction instead of a full burst.
  • The Forgotten: Skeleton charge will shoot bones and perform a melee swing, ghost works just like normal monstro's lung
