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 4.0 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.

Different characters start with varying range:

 * Range up pills increase range by 2.5  0.75, and range down pills decrease range by  2  0.60.
 * In co-op, Long Baby will occasionally briefly increase range, shot speed, and tear height. Dark Baby will occasionally briefly increase all stats, including shot speed. Dripping Baby will occasionally briefly grant, increasing range.
 * The card activates the  effect for the current room, which increases range.
 * The card increases range, damage, and Isaac's size for the current room.
