Binding of Isaac: Rebirth Wiki
Disambig.png This article is about the attribute. For Isaac's primary weapon, see effects.

Tears Stat Icon.png 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 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. Removed in Repentance 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.

Added in Repentance 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:

Direct modifiers to Tear Delay/Added in RepentanceTears Fired per Second[]

Several items directly modify tear delay after the main calculation:

  • Added in Repentance 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.

  • 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.
  • Removed in Repentance Charge-bar items like Monstro's Lung or Brimstone stop working at 30 tears per second. Spirit Sword instead constantly activates the spin attack.
