Monstro's Lung is a passive item.

Effect[]

  • Grants a charged shot that fires 14 tears in the same fashion as Monstro.
    • The attack can be released only when fully charged.
    • Removed in Repentance Tears down: Delay * 4.3.
    • Added in Repentance Fire rate is divided by 4.3 (roughly 0.23x).
    • Each tear has a random size multiplier between 0.9x to 1.33x, but there is no effect on damage.

Synergies[]

  • 20/20 20/20 / The Inner Eye The Inner Eye / Mutant Spider Mutant Spider: Adds 2, 5 or 7 tears to the barrage respectively. For the latter two, greatly slows down the charge.
    • 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.
  • Anti-Gravity Anti-Gravity: overidden, but tear delay down still applies, which greatly reduced the charge time, leading to better damage output.
  • 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 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 Azazel and Added in RepentanceTainted Azazel Tainted Azazel's versions of Brimstone.
    • + Added in RepentanceEye Sore Eye Sore Not recommended. Overrides this synergy with a chance to shoot 1-3 additional Brimstone lasers in random directions.
  • Added in RepentanceSoy Milk Soy Milk: Continuously fires shotgun-style tears without the need to release the attack button, resulting in a significant damage per second increase.
  • 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 Lilith's Incubus; picking up Chocolate Milk will significantly reduce damage and increase charge time.
    • Added in Repentance Tear delay is increased, and the tear damage, along with the amount of tears fired is dependent on charge time.
  • Added in Afterbirth Dr. Fetus Dr. Fetus: Isaac spits multiple bombs but must charge to fire. Bombs detonate simultaneously.
  • Added in Afterbirth Epic Fetus Epic Fetus: Launches 3-5 cursors that rotate around each other before the missiles land.
  • Added in Afterbirth †Flat Stone Flat Stone: All tears bounce simultaneously; the effective range is greatly increased.
  • Removed in Repentance Ipecac Ipecac: Isaac spews multiple Ipecac tears, with no increase in charge time.
    • Added in Repentance Isaac spews multiple Ipecac tears. Charge time is greatly increased.
  • Added in RepentanceTechnology Technology: Grants a charged shot, but rather than firing a cluster of tears, fires a cluster of zigzagging lasers in a short-range spread pattern.
    • +Soy Milk Soy Milk: Continuously fires laser clusters without having to charge.
  • Added in AfterbirthTech X Tech X: Fires a group of laser rings with size dependent on how long they were charged, with increased charge time.
  • Added in Afterbirth 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 Afterbirth Mom's Knife Mom's Knife: Fires an additional cluster of 3-5 knives when at maximum charge, each dealing 2x tear damage.
    • With two copies of Monstro's Lung, throws a fan of four extra knives alongside the basic attack regardless of charge.
  • Removed in Afterbirth † Mom's Wig Mom's Wig: All the spiders will spawn instantly while charging a shot.
    • Added in Repentance Amount of spiders spawned dependent on luck.
  • Monstro's Lung: Additional copies of the Lung add 10 tears to the barrage.
  • 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.

Interactions[]

  • Removed in Afterbirth Technology Technology: If picked up after Technology, Monstro's Lung has no effect. Technology will override Monstro's Lung with a very low firerate.
    • Added in Afterbirth / Removed in Repentance Charge effect is removed and fire rate returned to normal. Extra lasers will be shot in random directions around Isaac while firing.
    • Added in Repentance Grants a charged shot, but rather than firing a cluster of tears, fires a cluster of zigzagging lasers in a short-range spread pattern.
