Attributes

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.
- How many tears the character fires every 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.
How many tiles 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: $\frac{30}{\text{Tear Delay} + 1}$ .
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.
