Monstro's Lung

**Monstro's Lung** is a passive item.

## Effects

* Grants a charged shot that fires 14 tears in the same fashion as Monstro.
	+ 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: Tear Delay × 4.3 /  Fire Rate ÷ 4.3 (roughly 0.23x).

## Notes

* Charge time can be found with the following equation:

Fire Rate

{\displaystyle \text{(time)} = \frac{1}{30}(Roundup(\text{Tear Delay)}) \approx \frac{1}{\text{Fire Rate}}}

* Each tear has independant chance to have Tear Effects.
* Tear falling speed ups will slightly reduce the effective range of Monstro's Lung.
	+ Since range ups always add to tear falling speed, every range up reduces effective range.
* Multi-shot effects such as  or  Keeper adds 2.4 tears to the barrage per tear they normally grant. The resulting amount is rounded, and is capped at 50.

## Synergies

* /  / :
	+ 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.
	+ Adds multi-shot effect they normally grant (see Notes section).
		- Without any other multi-shot effect, the barrage size becomes 16/19/21 respectively.
* / : Fires automatically upon reaching full charge.
* : Hover effect is overidden, but tear delay down still applies, which greatly reduces the charge time.
* : All tears are larger, with increased damage (as opposed to every 2nd tear like Blood Clot alone).
	+ Tears have a 50% chance to be Blood Clot tears.
* : 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 and  Tainted Azazel's versions of Brimstone.
	+ Brimstone + : Overrides this synergy with a chance to shoot 1-3 additional beams in random directions.
* : 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.
	+ 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%.
* : Adds a chance to fire 1-3 additional barrages in random directions.
* : Monstro's Lung has priority. Does not apply Dr. Fetus' tears down. Fires 6 bombs which detonate simultaneously.
	+ Monstro's Lung has priority. Does not apply Dr. Fetus' tears down. Fires 6 mini-bombs which detonate at different times.
	+ Multi-shot effects add 1 bomb to the barrage, up to 21 bombs.
* : 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.
* : All tears bounce simultaneously; the effective range is greatly increased.
* : 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.
* : Fires a large number of extra tears alongside the burst that begin orbiting Isaac once they reach the orbit range.
* : Fires Ipecac tears, with no increase in charge time.
	+ Applies Ipecac's tears down.
* : 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 + : The lasers leave creep each time they arc, resulting in a massive amount of creep.
	+ Technology + : The 6x damage is recovered each time they arc, nearly nullifying the distance penalty.
* : 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.
	+ Increases Tear Delay.
	+ Fire Rate is divided by 3.1.
* : The Ludovico Technique has priority. Does not apply Monstro's Lung's tears down. A cluster of variably sized tears orbit the main tear.
* : Mom's Knife has priority. Does not apply Monstro's Lung's tears down. Fires additional knives depending on charge amount, each dealing 2x tear damage. Fires 3-5 knives at maximum charge.
* : Charging an attack spawns spiders in rapid succession.
	+ 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  / , add  10/ 12 tears to the barrage.
	+ This effects is equivalent of adding  4/ 5 multi-shot effects. The items which have priority over Monstro's Lung or override it (e.g. /) benefit from this multi-shot effect.
* : Tears stay in the air much longer and consistently, allowing better reach and more focused blasts before the tears returning to Isaac.
* : Replaces tears with white technology beams that slowly branch out like lightning.
* : All the tears follow the beam at different heights without spreading out, making it much easier for multiple tears to hit a target.

## Interactions

* : Overridden by Monstro's Lung.
	+ Tears have a 50% chance to be Chemical Peel tears.
* : Overrides Monstro's Lung.
* : Overridden by Monstro's Lung.
* : Overrides Monstro's Lung.
* : Tears stat is increased properly but firing cancels the effect.
* The Forgotten: Melee swing is unaffected, but the throw attack is replaced by the burst attack with small bones instead of tears.
* /  / : Fires 8 normal tears.
* : If Monstro's Lung is picked up while Kidney Stone is ready to fire, charge time for Monstro's Lung will be significantly decreased.
	+ Only stat effects from Kidney Stone apply.
* : The tears merge into one giant tears a while after being fired, and instantly burst. Without Piercing, most of the damage is often wasted. Without Spectral, the tears often collide against obstacles due to their size.
* / : Adds a chance to fire single tears in the other direction(s).
	+ Adds a chance to fire barrages in the other direction(s).
* : Overrides Monstro's Lung
* : Only stat effects from Marked apply.
	+ Works as expected. Fires automatically upon reaching full charge.
* : Overridden by Monstro's Lung.
* : The tears still fall after being fired.
* : Overrides Monstro's Lung.
* : 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.
* : Occasionally fires a linear laser while charging.
* : If picked up after Technology, Monstro's Lung has no effect. Technology will override Monstro's Lung with a very low firerate.
	+ Technology has priority. Does not apply Monstro's Lung's tears down. Fires extra lasers in random directions.
* : Fires a linear laser while charging.
* Ipecac + Dr. Fetus: Removes Explosion Immunity
* : 7-8 tears are fired at each diagonal direction instead of a full burst.
	+ Adds a multi-shot effect (see Notes section). Full-sized barrage on each diagonal direction.
