Template:DisambigMsg

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

The formula for tear delay is:

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

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

Different characters start with different initial tears:

• Isaac, Magdalene, Cain, Judas, ???, Eve, Lazarus, The Lost, Lilith, Apollyon, and The Forgotten: 0
• Samson: -0.05
• Azazel: +0.5, x1/3
• Eden: ±0.75
• Keeper: -2

Several items directly modify tear delay after this main calculation:

• Anti-Gravity: -2 tear delay
• Brimstone: tear delay * 3
• Cancer: -2 tear delay
• Capricorn: -1 tear delay
• Chocolate Milk + The Ludovico Technique: -1 tear delay
• Cracked Crown: -20% tear delay
• Cricket's Body: -1 tear delay
• Dr. Fetus: tear delay * 2.5
• Epiphora: tear delay / 2 (while at max "charge")
• Eve's Mascara: tear delay * 2
• Guillotine: -1 tear delay
• Ipecac: (tear delay * 2) + 10
• Milk!: -2 tear delay (after taking damage for the current room)
• Mom's Perfume: -1 tear delay
• Monstro's Lung: tear delay * 4.3
• Mutant Spider: (tear delay * 2.1) + 3
• Pisces: -1 tear delay
• Polyphemus: (tear delay * 2.1) + 3
• Purity: -4 tear delay while blue aura is active
• Soy Milk: (tear delay / 4) - 2
• The Inner Eye: (tear delay * 2.1) + 3

The minimum tear delay that can be reached with regular tears up items is 5, but with items that directly reduce tear delay, tear delay can reach a minimum of 1.

The number of tears per second that the player fires is found by the formula: $\frac{30}{TearDelay + 1}$.

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.
