Technology 2 is a passive item.


  • Replaces Isaac's right eye tears with an unlimited range piercing laser which fires continuously, dealing damage 15 times per second.
  • Removed in Repentance x0.65 Damage multiplier.
  • Removed in Repentance The laser deals 20% of Isaac's damage per tick.
    • This compounds with the damage down for a total of 13% of Isaac's damage per tick.
  • Added in Repentance Only the laser deals 13% of Isaac's damage per tick.
  • Added in Repentance Tears fired per second * (2/3).
  • Added in Repentance Laser is able to knock back enemies.


  • Tear delay is effectively doubled, as Isaac will do a bit of the animation to fire a right eye tear, but no tear will come out.
  • Charged shots are not affected by the effective tear delay down, as they don't use the alternative left eye/right eye fire scheme.
  • Removed in Repentance As Cain Cain can only fire tears from his right eye, Technology 2 will replace his tears altogether unless he has Technology Technology or a charged attack.
    • Added in Repentance When used by Cain, or a character that is forced to fire from one eye due to the effects of Stapler Stapler or Lead Pencil Lead Pencil, they will fire Technology Technology lasers out of their right eye instead of their normal tears, as long as they have no other items that replace their tears (Neptunus Neptunus lets them fire tears normally). These lasers cannot be angled with momentum.
  • Removed in Repentance Because Lilith Lilith is blindfolded and relies on her Added in AfterbirthIncubus Incubus, the only effect gained from Technology 2 is the damage down.
    • Added in RepentanceIncubus can fire laser as normal; stat effects apply.
    • Unlike regular Lilith, Tainted Lilith Tainted Lilith gains the standard laser from her baby as well as the tears from the demonic baby.
  • The laser can apply status effects very efficiently due to its high tick rate.


  • Added in Afterbirth8 Inch Nails 8 Inch Nails / Added in AfterbirthBlister Blister / Pisces Pisces: The laser will consistently push back enemies.
  • Blood Clot Blood Clot / Chemical Peel Chemical Peel: Since Isaac's right eye is replaced by Technology 2, he can only fire tears from his left eye, which gives all his tears higher damage and range.
  • Chocolate Milk Chocolate Milk: The laser fires while Chocolate Milk charges at normal rate.
  • Added in Repentance Cricket's Body Cricket's Body / The Parasite The Parasite: The laser will rapidly split into small low damage tears upon impact with an enemy or obstacle.
  • Cursed Eye Cursed Eye: The laser fires while Cursed Eye charges at normal rate, retaining the teleporting effect.
    • Added in Repentance Tears are replaced with lasers, fired from the same eye of Technology 2.
  • Epic Fetus Epic Fetus: The laser fires while the missiles are being aimed.
  • Added in AfterbirthExplosivo Explosivo A chance of attaching explosive tears to enemies when they laser touches them.
  • Fire Mind Fire Mind: Laser will set enemies on fire but will not explode.
  • Ipecac Ipecac: Laser damage increases dramatically while also gaining the poison effect.
  • Added in RepentanceLachryphagy Lachryphagy: The laser has its range shortened but rapidly creates and feeds Lachryphagy tears.
  • Lost Contact Lost Contact: The laser destroys all hostile projectiles that come into contact with it.
  • The Ludovico Technique The Ludovico Technique: Isaac simultaneously controls a tear and fires the laser; however, Isaac will only fire the Technology 2 laser in the direction that the tear is currently facing.
  • Added in AfterbirthA Lump of Coal A Lump of Coal: Damage increases the further away the enemy is, on a multiplier that is roughly +20% per tile of distance.
  • Added in AfterbirthMarked Marked: Isaac simultaneously controls a big red target on the ground and fires the laser in the cardinal directions.
    • Added in Repentance The laser now continuously fires towards the crosshair along with tears.
  • Mom's Knife Mom's Knife: The laser fires while the Knife charges at normal rate.
  • Monstro's Lung Monstro's Lung: The laser fires while Monstro's Lung charges at normal rate. No reduction in tear burst size.
  • Added in AfterbirthRubber Cement Rubber Cement: Laser bounces off of walls.
  • Removed in RepentanceTechnology Technology: Equips two lasers that can be fired at the same time. As Technology is always fired from the right eye, it is not affected by the halved normal attack rate.
    • Added in Repentance Technology is affected by the fire rate multiplier. Holding Stapler Stapler, Lead Pencil Lead Pencil or playing as Cain Cain will allow Isaac to angle shots with momentum again.
  • Tiny Planet Tiny Planet: The laser spirals around Isaac once and then goes straight again.
  • Added in AfterbirthThe Wiz The Wiz: Tears are fired diagonally while the laser is fired straight forward.


  • Azazel Azazel: The Technology 2 laser continuously fires as Azazel charges his Brimstone.
    • Removed in Repentance Damage is still reduced.
  • Removed in AfterbirthBrimstone Brimstone: Overrides Technology 2, but retains the reduced damage.
    • Added in Afterbirth Laser fires continuously while Brimstone charges at normal rate.
  • Removed in RepentanceIncubus Incubus: Decreases damage of Incubus' tears; Incubus does not fire a continuous laser.
  • Removed in RepentanceLead Pencil Lead Pencil: Isaac loses the ability to fire tears from the remaining eye, identical to Cain's downside.
    • Added in Repentance Replaces tears with lasers similar to Technology Technology. These are shot from the eye that shoots Technology 2, doing damage alongside the Technology 2 beam.
  • Added in Afterbirth / Removed in RepentanceMy Reflection My Reflection: Laser is bent in the opposite direction as Isaac moves sideways, then gradually becomes straight as he stands still.
    • Added in Repentance The laser makes a thin loop in front of Isaac, and fires the normal laser backwards.
  • Added in RepentancePop! Pop!: The laser has drastically reduced range, and eyeball tears are rapidly created at the end of the laser.
  • Removed in RepentanceSoy Milk Soy Milk: Both damage reductions are applied, along with removing one eye's worth of tears.
  • Technology 2 Technology 2: Multiple copies of the item provide no benefit.
