Range

Range determines how long tears will travel before landing and is represented by a bow and arrow. Effective range is determined by a combination of the range stat, shot speed, and shot height.

This attribute's name is misleading because range determines the time that a shot stays in the air rather than the "distance" that it travels. The effective range is calculated based on said travel time, shot speed, and shot height. Range cannot be lowered below 5.0 but has no upper limit.

Range now represents how many tiles a tear will travel. Range cannot be lowered below 1.0, but has no upper limit.

Extremely high range makes Isaac's tears start so high in the air they can cross over obstacles as if they were spectral, but they won't go through the room walls. Once the tears fall down, they will start hitting obstacles again. This compounds with the height gain from the hidden tear height stat.

Each character's base range is as follows:

Character	Range
Cain Azazel Lazarus Tainted Judas Tainted Lazarus	4.5
Samson Jacob Tainted Samson	5.0
Isaac Magdalene Judas Dark Judas ??? Eve Lazarus Risen The Lost Lilith Keeper Apollyon The Forgotten The Soul Bethany Tainted Isaac Tainted Magdalene Tainted Cain Tainted ??? Tainted Eve Tainted Azazel Dead Tainted Lazarus Tainted Lost Tainted Lilith Tainted Keeper Tainted Apollyon Tainted Forgotten Tainted Bethany Tainted Jacob	6.5
Esau	8.0

Character	Range
Cain Azazel Lazarus	17.75
Samson	18.75
Isaac Magdalene Judas Dark Judas ??? Eve Lazarus Risen The Lost Lilith Keeper Apollyon The Forgotten The Soul	23.75

Azazel: The mini-blood barrage doesn't calculate its Range the same way as normal tear attacks, so his Range stat is misleading. His attack has a much shorter Range than other characters with the same value.
Eden: Range is a random value between 18.75 and 28.75, inclusive.
Eden and Tainted Eden: Range is a random value between 5.0 and 8.0, inclusive.
The Forgotten and Tainted Forgotten's melee attacks don't calculate their Range the same way as normal tear attacks, and their actual attack range is far less than other characters with the same value.
Tainted Azazel: The blood barrage has unlimited Range, so his Range stat isn't commonly relevant.
Tainted Soul: Incapable of firing tears.
