Technology Zero 
Effects
- Connects tears with electricity that damages enemies.
- (Removed in Repentance) The electricity's damage is equal to Isaac's Damage.
- (Added in Repentance) The electricity deals 30% of Isaac's Damage, 15 times per second.
- A tear can generate one connection. The tear does not generate another connection even after the connection is lost. However, other tears can still make connections with it.
- Each of Isaac's tears can connect to other allied tears Including those of shooting familiars.
- The number of connections is limited by the number of Isaac's tears.
Notes
Synergies
Anti-Gravity: All of the tears fired are connected by electricity, creating a series of electric fences.
Apple! /
Tough Love: The damage of the electricity can be multiplied by the items. This occurs independantly from the tears which generated the electricity.
Cricket's Body /
Compound Fracture /
The Parasite: Split tears will be connected via electricity.
Evil Eye: Tears fired by eye will be connected via electricity to Isaac's tears.
- (Added in Repentance)
Eye of the Occult: Allows you to move the electrified tears, allowing you to hit more enemies and do more damage.
- (Added in Repentance)
Haemolacria: Main tears and bursts can be connected via electricity.
Pop!: Tears in midair and tears that knock around each other will still be connected, effectively creating electric barriers.
Proptosis: Triples the electricity damage. Has no penalty with range.
Sinus Infection: Boogers will have electricity flowing between them even if attached to the same enemy, dealing massive damage to bosses.
Sulfuric Acid / (Added in Repentance)
Terra: The lasers are capable of destroying terrain, but is unable to apply knockback, allowing to easily destroy large quantities of obstacles.
Tiny Planet: Creates moving laser fields that orbit the character.
The Wiz: The diagonally-spreading tear shots will be connected by electricity, effectively making up for the item's blind spot and providing an attack with a very wide range.
Interactions
- The following items override Technology Zero. Tears from other sources such as
Lead Pencil can still generate electricity with each other.
Continuum: Tears will travel through walls; however, the electricity will not connect the tears while they are outside the room. If a tear was connected before it pass through a wall, it will not be connected after passing through, limiting the efficiency of the combination.
Flat Stone: Tears lose their connection as they bounce. As such, tears cannot make connection to another tear once they bounce, but other tears can make connection to them.
- (Removed in Repentance)
Haemolacria: Only main tears can be connected.
