The Tears attribute affects the rate of fire of the character and is represented by 3 arrows. This attribute is related to tear delay (the delay between successive shots, as opposed to the inverse 'tears per second'); a higher tears stat means a shorter delay and a higher fire rate. 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:
"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: .
Conversely, Tear Delay can be calculated from the fire rate given ingame with the formula . Note that the fire rate given by the ingame HUD is rounded.
Tear delay as a mechanic is no longer as significant in Repentance, and instead items that used to affect the tear delay now instead affect the fire rate directly. Effectively, this means tear delay can be less than 1.
- The absolute maximum fire rate achievable is 120, corresponding to -0.75 tear delay.
Different characters start with different initial tears:
- Eden/ Tainted Eden: ±0.75
- Tainted Eden's base tears rerolls every time they take damage unless they have Birthright.
- Azazel: +0.5, x1/3
- Tainted Jacob: +0.277
- Jacob and Esau: +0.277 for Jacob, -0.1 for Esau
- Samson: -0.05
- Samson: -0.1
- Tainted Samson: -0.1
- Tears fired per second is halved and then increased by 2 while berserking.
- Tainted Samson: -0.1
- Dead Tainted Lazarus: -0.1
- Tainted ???: -0.4
- Tainted Apollyon: -0.5
- Tainted Eve: -0.5, then x0.66 (Has a 3.3 TPS softcap)
- Keeper: -2
- Keeper: -1.9
- Tainted Keeper: -2.2
- Some characters have tears multipliers that decrease or increase all tear changes
- Azazel: x0.33
- Tainted Azazel: x0.33
- The Forgotten/ Tainted Forgotten: x0.5
- Tainted Eve: x0.66 (Has a 3.3 TPS softcap)
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. Generally, for these items, each unit of tear delay in Afterbirth+ and before converts to +0.5 tears per second in Repentance.
|Item||Tear delay adjustment||Fire rate adjustment|
|Chocolate Milk||x2.5 (for maximum charge)||No change, displayed value = maximum charge time|
|Cracked Crown||x0.8||Fire rate over base value x1.2|
|Epiphora||x0.5 (while at maximum "charge")||x2 (while at maximum "charge")|
|Haemolacria||x2, then +10
x2, then +11
|Tear delay adjustment, not fire rate|
|Ipecac||x2, then +10||x1/3|
|Mutant Spider||x2.1, then +3||x0.42|
|Polyphemus||x2.1, then +3||x0.42|
|Soy Milk||x0.25, then -2||x5.5|
|The Inner Eye||x2.1, then +3||x0.51|
|Brittle Bones||N/A||+0.4 per bone heart lost|
|Dark Prince's Crown||N/A||+2|
|Death's List/ Void/ Black Rune||N/A||+0.5|
|Berserk!||N/A||x0.5, then +2|
|Bloody Gust||N/A||Up to +3 after taking damage 6 times|
|Tainted ???/ IBS/ Soul of ???||N/A||+1.5 while on unique creep|
Additional x3 if the creep is in contact with white poop
|It Hurts||N/A||+1.2 on the first hit, then +0.4 on subsequent hits|
|Luna||N/A||+1 for the first beam of light, then +0.5 for subsequent beams|
|Paschal Candle||N/A||+0.4 for every room cleared without taking non-self damage, up to +2 total|
|Wavy Cap||N/A||+0.75 (halved if Isaac leaves the room, and wears off at the rate of one room clear per use)|
- 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.
