Shot Speed Stat Icon Shot Speed is the attribute that governs how quickly an individual tear travels and is represented by a speeding ball.

(except in Repentance) Shot Speed also affects the effective range of the tears. As the range stat determines how long tears will stay in the air (and not distance traveled), a lesser shot speed reduces effective range.

Shot speed measures the velocity of each tear in contrast to the Tears stat, which measures tear frequency.

A tear traveling at 1.0 shot speed crosses one tile in 4 ticks (8 frames, or 0.133 seconds), giving a velocity of 7.5 tiles per second. Higher and lower values of the attribute scale the velocity linearly.

Notes[ | ]

  • All characters start with the same shot speed except for Character Samson iconSamson, who has 1.31 shot speed, Character Jacob iconJacob, who has 1.15 shot speed, Character Esau iconEsau, who has 0.85 shot speed, and Character Eden iconEden, whose shot speed can be anywhere between 0.75 and 1.25.
  • A higher shot speed will increase the directional knockback of enemies hit by the tears.
  • Having a high shot speed is not always desirable. While a high shot speed means enemies are easier to aim at, (except in Repentance) and effective range is increased , it also means more knockback, which can make enemies move in unpredictable ways, potentially damaging Isaac and making it harder to land consecutive shots. Some items will also directly benefit from low shot speed, such as (except in Rebirth)Collectible Tech X iconTech X and (in Afterbirth † and Repentance)Collectible Trisagion iconTrisagion, and particularly items that grant homing tears, such as Collectible Godhead iconGodhead and Collectible Spoon Bender iconSpoon Bender.
  • Items that reduce shot speed cannot lower it past 0.6.
