The Tears attribute affects the rate of fire of the character and is represented by 3 arrows. It is used to calculate the tear delay, which in turn is used to calculate the fire rate (number of tears fired per second). Higher tears decreases tear delay, and lower tear delay increases fire rate.
Fire Rate Calculation[]
The formulas for tear delay and fire rate are:
- is the tears stat.
- is the tears cap, defined as the number that brings you to 5 tear delay (and therefore 5 fire rate) assuming no direct modification to tear delay or fire rate. Increasing the tears stat beyond this does nothing.
- Tear Delay is rounded down to the nearest integer. is just under 1.37, meaning two items with +0.7 tears is enough to get your tear delay to under 6 and therefore to 5, assuming you start at 0.
- Tear Delay is no longer rounded down. is just under 1.82.
Tear delay is therefore the additional delay between fired tears beyond 1/30 seconds, in units of 1/30 seconds. For example, 7 tear delay means 8/30 seconds between tears, or 30/8 = 3.75 fire rate.
Items can directly reduce tear delay.
- The minimum tear delay is 1, corresponding to 15 fire rate.
- Tear delay reduction has accelerating returns, meaning each -1 tear delay is more effective the more tear delay reduction (and the higher tears stat) you have.
Almost all direct tear delay reduction is replaced with fire rate increase.
- Generally, each -1 tear delay is replaced with +0.5 fire rate increase.
- The maximum fire rate is 120, corresponding to -0.75 tear delay.
- Damage per second depends linearly on fire rate, meaning it is more effective as a percentage increase the less of it you have (and the less tears stat you have).
Characters[]
Different characters start with different initial tears:
- Samson/ Tainted Samson: -0.1
- Azazel: +0.5, x0.267
- Eden: ±0.75
- Eden/ Tainted Eden: +0.75 to -0.5
- Tainted Eden's base tears rerolls every time they take damage.
- Eden/ Tainted Eden: +0.75 to -0.5
- Keeper: -2
- Keeper: -1.9
- Tainted Keeper: -2.2
- Jacob and Esau: +0.277 for Jacob, -0.1 for Esau
- Tainted Jacob: +0.277
- Tainted ???: -0.35
- Tainted Eve: -0.5, then x0.66 (Has a 3.3 TPS softcap)
- Dead Tainted Lazarus: -0.1
- Tainted Apollyon: -0.5
- 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 (2.73) tears.
- Some characters have tears multipliers that decrease or increase all tear changes:
- Azazel: x0.267
- Tainted Azazel: x1/3
- The Forgotten/ Tainted Forgotten: x0.5
- Tainted Eve: x0.66 (Has a 3.3 TPS softcap)

Notes[]
- 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 fire rate.
