Hidden Attributes

This article is about the attribute. For Isaac's primary weapon, see effects.

The Tears attribute determines the rate of fire of the character and is represented by 3 arrows. This attribute is also known as the tear delay (the delay between successive shots, as opposed to the inverse 'tears per second'); a higher tears stat means a shorter delay. The tear stat is a measurement of tear frequency, as opposed to Shot Speed, which measures how fast those shots move.

Tear Delay Calculation

The formula for tear delay is:

${\text{Tear Delay}}={\begin{cases}16-6\times {\sqrt {T\times 1.3{+}1}}&{\text{if }}T\geq 0\\16-6\times {\sqrt {T\times 1.3{+}1}}-6\times T&{\text{if }}T<0{\text{ and }}T>-0.77\\16-6\times T&{\text{if }}T\leq -0.77\end{cases}}$

"T" in the above formula is equal to the normal tears stat, with all adjustments added together. For example, picking up The Sad Onion would grant 0.7 tears, making Isaac's tear delay 7.7, which is rounded down to 7.

The minimum tear delay that can be reached with regular tears up items is 5, giving Isaac a soft cap of 5 tears fired per second. With items that directly reduce tear delay, tear delay can be reduced further, down to a hard minimum of 1 tear delay (15 tears fired per second).

The number of tears per second that Isaac fires is found by the formula: ${\frac {30}{{\text{Tear Delay}}+1}}$.

Conversely, Tear Delay can be calculated from the fire rate given ingame with the formula ${\frac {30}{\text{Fire Rate}}}-1$. Note that the fire rate given by the ingame HUD is rounded.

The tear delay hard cap of 1 is removed, allowing Isaac to shoot much faster than before with the right combination of items. Additionally, many items have had their effects changed to change Isaac's tears fired per second rather than his tear delay.

• The absolute maximum fire rate achievable is 120.

Characters

Different characters start with different initial tears:

• Samson: -0.05
  • Samson: -0.1
• Azazel: +0.5, x1/3
• Eden/ Tainted Eden: ±0.75
  • Tainted Eden's base tears rerolls every time they take damage unless they have Birthright.
• Keeper: -2
  • Keeper: -1.9
• The Forgotten/ Tainted Forgotten: x0.5
• Jacob and Esau: +0.277 for Jacob, -0.1 for Esau
• Tainted ???: -0.4
• Tainted Eve: -0.5, then x0.66
• Tainted Samson: -0.1
  • Tears fired per second is halved and then increased by 2 while berserking.
• Tainted Azazel: x0.33
• Dead Tainted Lazarus: -0.1
• Tainted Keeper: -2.2
• Tainted Apollyon: -0.5
• Tainted Jacob: +0.277
  • All other characters ( Isaac, Magdalene, Cain, Judas, Dark Judas, ???, Eve, Lazarus, The Lost, Lilith, Apollyon, The Soul, Bethany, Tainted Isaac, Tainted Magdalene, Tainted Cain, Tainted Judas, Tainted Lazarus, Tainted Lost, Tainted Lilith, and Tainted Bethany) have the base +0 tears.

Direct modifiers to Tear Delay/Tears Fired per Second

Several items directly modify tear delay after the main calculation:

• Many items that used to modify tear delay now modify tears fired per second instead. They still allow the soft cap of 5 tears per second to be broken, but now have a greater impact on runs that have a lower fire rate compared to those with a higher one; this is in contrast to Afterbirth+, where the opposite was true.
• Anti-Gravity: -2 tear delay
  • +1 tears fired per second
• Brimstone: tear delay * 3
• Cancer: -2 tear delay
  • +1 tears fired per second
• Capricorn: -1 tear delay
  • +0.5 tears fired per second
• Chocolate Milk: tear delay * 2.5
  • This fire rate modifier does not affect Isaac's actual tears stat; it's only the rate at which fully charged shots can be fired.
• Cracked Crown: -20% tear delay
  • : Boosts the tears fired per second given by normal tears upgrades by 20%
• Cricket's Body: -1 tear delay
  • +0.5 tears fired per second
• Dr. Fetus: tear delay * 2.5
• Epiphora: tear delay / 2 (while at max "charge")
• Eve's Mascara: tear delay * 2
  • Eve's Mascara: tear delay * 1.5
• Guillotine: -1 tear delay
  • +0.5 tears fired per second
• Haemolacria: (tear delay * 2) + 10
• Hallowed Ground: tear delay / 2
  • : Tears fired per second * 2.5
• Ipecac: (tear delay * 2) + 10
  • Tears fired per second / 3
• Milk!: -2 tear delay (after taking damage for the current room)
  • +1 tears fired per second
• Mom's Perfume: -1 tear delay
  • +0.5 tears fired per second
• Monstro's Lung: tear delay * 4.3
• Mutant Spider: (tear delay * 2.1) + 3
• Pisces: -1 tear delay
  • +0.5 tears fired per second
• Polyphemus: (tear delay * 2.1) + 3
• Purity: -4 tear delay while blue aura is active
  • : +2 tears fired per second
• Soy Milk: (tear delay / 4) - 2
  • Tears fired per second * 5.5
• Technology 2: tear delay * 1.5
• The Inner Eye: (tear delay * 2.1) + 3
  • (tear delay * 2)
• Brittle Bones: +0.4 tears fired per second per bone heart lost
• Dark Prince's Crown: +2 tears fired per second
• Death's List/ Void/ Black Rune: +0.5 tears fired per second
• Almond Milk: Tears fired per second * 4
• Berserk!: (Tears fired per second / 2) + 2
• Consolation Prize: +0.5 tears fired per second
• Tainted ???/ IBS/ Soul of ???: +1.5 tears fired per second while standing on unique creep
  • This also triples fire rate if the creep is in contact with white poop
• It Hurts: +1.2 tears fired per second on the first hit, then +0.4 tears fired per second on subsequent hits
• Luna: +1 tears fired per second on touching the first beam of light, then +0.5 tears fired per second on subsequent beams touched
• Paschal Candle: +0.4 tears fired per second for every room cleared without taking non-self damage, up to a max of +2 tears fired per second
• Wavy Cap: +0.75 tears fired per second (halves if Isaac leaves the room he used it in, and wears off at the rate of one room clear per use)

Notes

• Assuming no other modifications to the tears stat, +1.4 tears up is enough to bring you to the normal delay cap. In this case, it would reduce the delay to 5.92, which rounds down to 5.
• With a tear delay of 1, the maximum achievable rate of fire is 15 tears per second (every 4 frames).
• Polyphemus, Mutant Spider, and Inner Eye's tear delay formulas do not stack with each other, meaning that there is no downside to taking another after you have already taken one.
• Charge-bar items like Monstro's Lung or Brimstone stop working at 30 tears per second. Spirit Sword instead constantly activates the spin attack.
