Attributes, also known as stats, are the numerical values of a character that affect their performance and the behavior of their tears, the game's primary weapon. All characters start with a different set of values and they can be increased or decreased during a run. The seven main stats are:
Health: The amount of damage the character can take before dying.
Speed: How quickly the character moves.
Tears: The character's rate of fire. The lower the number, the faster tears are fired.
As of Repentance, Isaac's tear rate is shown in tears fired per second; the higher the number, the faster tears are fired.
- Damage: The amount of damage that each of the character's tears deals to enemies.
- Range: How long the character's tears will travel before landing.
- Shot speed: How quickly the character's tears travel.
- Luck: Affects a variety of chance-based effects.
Additionally, there are a few Hidden Attributes.
Stat Screen[]
Most attributes can be viewed on the pause menu, except for health (which is shown in the game HUD). The pause menu's attributes are shown on an imprecise scale from 1 to 7 (
0 to 7), and the values are as follows:
| Attribute | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
|---|---|---|---|---|---|---|---|
| Speed | 0.10 - 0.99 | 1.00 - 1.49 | 1.50 - 1.99 | 2.00 | N/A | N/A | N/A |
| Tear Delay | ≥8 | 7 - 6 | 5 - 4 | N/A | 3 | N/A | 2 - 1 |
| Damage | 0.00 - 2.99 | 3.00 - 4.49 | 4.50 - 5.99 | 6.00 - 7.49 | 7.50 - 8.99 | 9.00 - 10.49 | ≥10.50 |
| Range | ≤19.99 | 20.00 - 39.99 | 40.00 - 59.99 | 60.00 - 79.99 | 80.00 - 99.99 | 100.00 - 119.99 | ≥120.00 |
| Shot Speed | 0.60 - 0.99 | 1.00 - 1.49 | 1.50 - 1.99 | 2.00 - 2.49 | 2.50 - 2.99 | 3.00 - 3.49 | ≥3.50 |
| Luck | ≤1 | 2 | 3 | 4 | 5 | 6 | ≥7 |
- Tear falling speed increases range stat in the pause menu by 1 for every 0.5 tear falling speed added.
| Attribute | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
|---|---|---|---|---|---|---|---|---|
| Speed | 0.10 - 0.66 | 0.67 - 0.88 | 0.89 - 1.11 | 1.12 - 1.33 | 1.34 - 1.55 | 1.56 - 1.77 | 1.78 - 1.99 | 2.00 |
| Fire Rate | ≤1.58 | 1.59 - 2.32 | 2.33 - 3.13 | 3.14 - 3.99 | 4.00 - 4.91 | 4.92 - 5.86 | 5.87 - 6.86 | ≥6.87 |
| Damage | 0.00 - 1.69 | 1.70 - 2.83 | 2.84 - 4.21 | 4.22 - 5.84 | 5.85 - 7.69 | 7.70 - 9.77 | 9.78 - 12.06 | ≥12.07 |
| Range | ≤4.24 | 4.25 - 5.74 | 5.75 - 7.24 | 7.25 - 8.74 | 8.75 - 10.24 | 10.25 - 11.74 | 11.75 - 13.24 | ≥13.25 |
| Shot Speed | 0.60 - 0.69 | 0.70 - 0.89 | 0.90 - 1.09 | 1.10 - 1.29 | 1.30 - 1.49 | 1.50 - 1.69 | 1.70 - 1.89 | ≥1.90 |
| Luck | ≤-1.51 | -1.50 - -0.51 | -0.50 - 0.49 | 0.50 - 1.49 | 1.50 - 2.49 | 2.50 - 3.49 | 3.50 - 4.49 | ≥4.50 |
The pause menu stat screen is made almost completely irrelevant by the introduction of the "Found Hud" feature in the Afterbirth+ DLC. Once it is enabled from the in-game options, the player's stats will be displayed in numerical form below the key count.
Found HUD[]
Some stats on the Found HUD are calculated and displayed differently from the internal, technical side of stats.
- Damage: Simply displays base damage per tear, without considering any special tear effects.
- Tears: Displayed as "tear delay" or "tears per second".
- To convert the internal tear delay to "Tears per second", use this formula: .
- Range: Displayed as approximate "tear lifespan" per tear or "range in tiles".
- There is no straightforward conversion from tear lifespan to range in tiles, as tear falling speed and shot speed are also involved.
