Tech X

Tech X is a passive item added in Afterbirth.

Effects

Isaac's tears are replaced with laser rings.
- Shots can be charged to increase the size of the rings.
- Only the outer circumference of the rings will deal damage.
- Rings pass through obstacles and enemies.
- Rings have infinite range and will travel until they hit a wall.

Notes

The rings are similar in appearance to the combination of The Ludovico Technique and Technology.
The laser rings will linger for a brief moment upon touching a wall, allowing more damage to be dealt to enemies closer to walls.
The "R U A WIZARD?" pill effect does not work with Tech X.
Charging only increases size, not damage. It is useful for hard-to-hit enemies, or hitting a wide area at once, but spamming small, uncharged shots will lead to much higher damage output.

Synergies

20/20: Shoots two rings instead of one.
Brimstone: Fires a brimstone circle instead of a tech circle.
- Azazel: Picking up Brimstone will still override Tech X. When you pick up Tech X as Azazel with his inherited Brimstone, Tech X does nothing at all.
  - As Azazel, Brimstone no longer overrides Tech X, and the two interact normally.
Chocolate Milk: Reduce the charge time. No effects on damage.
The Common Cold: The laser ring becomes green and inflicts poison.
Continuum: The ring will go over the wall and come out the opposite one.
- Continuum + Incubus: Incubus's laser rings cannot go through walls.
Diplopia: Picking up 2 copies of Tech X will cause two rings to fire instead of one, similar to the 20/20 effect.
Dr. Fetus: Shoots a laser ring with a bomb in the middle. Overrides the charging effect, replacing it with normal firing mode. Sometimes killed enemies will drop black hearts.
Epic Fetus: Each missile shoots 10 laser beams like from Technology in each direction, similar to Tammy's Head.
Eve's Mascara: Laser rings move slower, increasing damage as enemies spend more time in the laser. Rings also appear thicker.
Lazy Worm: Slows the ring, increasing damage as enemies spend more time in the laser.
Lost Contact: The rings have a chance to block enemy shots.
Maw Of The Void: If charged for long enough, a cross-shaped marker will appear on the goggles and the black aura will activate upon release of the attack keys.
Mom's Eyeshadow: Adds the charm effect to the laser ring.
Mom's Knife: Simultaneously fires the knife and laser ring(s).
- Mom's Knife + Incubus: Allows the Incubus to fire laser rings as fast as the player can press and release the fire button.
- Mom's Knife + Brimstone: Fires the knife and a brimstone ring, then a barrage of knives depending on how long it was charged.
Monstro's Lung: Extra laser rings with different sizes depending on how long Isaac charges it are fired, will increase charge time.
Mutant Spider: Shoots four rings instead of one.
Pupula Duplex: Increases the size of the rings.
Soy Milk: Charges up extremely quickly, almost as fast as you can press the button. Greatly reduces damage per ring. (Tendinitis warning!)
Spoon Bender: While the rings won't home in on enemies, they will bend inwards to hit enemies within each ring, resulting in a substantial damage area increase.
Strange Attractor: Magnetic effect pulls pickups and objects to the edge of the ring, increasing accuracy.
Technology/Tech.5: Equips both laser systems.
Technology 2: Equips both laser systems with the damage down from Technology 2.
The Inner Eye: Shoots three rings instead of one.
Wiggle Worm: Replaces the outer laser ring with a star-shaped oval, slightly increasing its area of effect.
