Tech.5 is an unlockable passive item.



  • The damage of the laser scales directly with Isaac's damage.
  • Unlike 15►Technology Technology or 15►Technology 2 Technology 2, Isaac can still fire tears from both eyes in addition to firing the laser.
  • The laser can be fired independently from tears by slightly tilting the right analog stick, just like shooting familiars.
  • Added in Repentance Unlike 15►Technology Technology, Tech.5 Lasers do not have momentum, and fire exclusively in the cardinal directions unless Isaac has an item like Added in Afterbirth †15►Analog Stick Analog Stick, Added in Repentance15►Eye of the Occult Eye of the Occult or Added in Afterbirth15►Marked Marked.


  • Added in Repentance15►Anti-Gravity Anti-Gravity: Creates floating laser balls that will all fire simultaneously when the fire button is released.
  • 15►Brimstone Brimstone: Tech.5 does not fire. However, it will still fire when playing as Azazel Azazel with his short-ranged Brimstone. Since the laser scales with player damage, this can be a devastating combination.
    • Added in Afterbirth Tech.5 fires normally while Brimstone laser is charging.
  • Removed in Repentance 15►Cricket's Body Cricket's Body: Tear delay down as expected, but no benefit from the splash effect.
    • Added in Repentance Releases a 4-way spread of tears whenever the laser hits a wall or an enemy.
  • Added in Afterbirth Lilith Lilith: No effect, as Lilith is inherently Blindfolded.
  • 15►The Ludovico Technique The Ludovico Technique: Laser is fired in the same direction that the controlled tear is moving.
  • Added in Repentance15►Ipecac Ipecac: Laser explodes and poisons enemies on contact.
  • 15►Rubber Cement Rubber Cement: Laser will bounce in angle depending on the obstacle hit.
