The Ludovico Technique

The Ludovico Technique is a special passive item.

Effects

 * Instead of firing tears, Isaac controls one floating tear that hovers over obstacles. This tear deals constant damage when held in place over an enemy.

Synergies

 * : One smaller tear orbits the main tear.
 * : The tear becomes a nail, increases in size, damage, and provides minor knockback in the direction the tear moves.
 * / / : The tear can gain the damage multiplier from each of the items, using the appropriate appearance when it happens. Euthanasia retains its instant kill ability against non-boss enemies.
 * : The tear steadily cycles between red and "normal," dealing more damage when red.
 * : Tear takes the shape of a very large laser ring. Shot speed is ignored. The Tears stat is ignored and damage is dealt very rapidly at a rate equivalent to 2 tear delay. This ring will always be present and doesn't need charging up like normal Brimstone would.
 * + : The ring increases in diameter, but not damage, the farther away it gets from Isaac.
 * + : The ring reaches out to attack enemies near it, reforming into a ring when no enemies are present.
 * + : The ring is visually identical to a normal Brimstone ring, but the 1.5x damage multiplier applies.
 * + : The ring takes the shape of a star.
 * Azazel: Same effect as with Brimstone, but damage is halved.
 * Azazel + : Full damage of the laser ring is regained.
 * : Tear will alternate between "normal" and red, dealing more damage when red.
 * : No damage increase, but results in -1 tear delay.
 * : The tear pulses green, poisoning enemies.
 * : Shoots out smaller tears when attacking an enemy.
 * : Damage bonus increases until it hits the max of 2x. Since the controllable tear never hits the ground or wall, the bonus cannot be lost.
 * : The tear becomes a scythe (vanity), but increases in size and damage
 * : The bomb can be controlled until it explodes.
 * The Forgotten: The tear follows the Forgotten when in its skeleton form. It can be hit with its melee attack to propel it, making it do more damage. When switching to the Soul, the tear spawns on top of the player.
 * The Forgotten + : The second tear acts exactly like the first and can also be hit to propel it.
 * : The tear homes towards nearby enemies and gains a large damaging aura.
 * Guppy transformation: A large number of flies is rapidly deployed whilst controlling the Ludovico tear.
 * : Isaac gains a controlled tear while also being able to shoot normally with Incubus. Incubus's tears gain piercing and spectral properties.
 * : Two smaller tears orbit the main tear.
 * : Tear will block enemy tears without disappearing.
 * : The tear becomes larger the further away it is from Isaac, increasing in damage.
 * : Tear randomly alternates colors, which randomly petrifies enemies.
 * : Tear gains a chance to give the fear effect.
 * : The item causes spiders to spawn rapidly when moving the tear.
 * : Tear turns red and does more damage.
 * Tear becomes a cluster of variously sized tears spread over a small area. The tears move at the same speed when controlled but constantly move around each other.
 * : Three smaller tears orbit the main tear.
 * : The tear moves much faster.
 * : The tear deals damage to enemies much faster, with the range penalty having no effect.
 * : Shoots out smaller tears when attacking an enemy.
 * : The tear deals damage, even if the enemies are stopped. Moving the tear unpauses the enemies.
 * : The tear pulsates in midair, expanding and contracting. This works with normal tears as well as.
 * : Tear will slightly gravitate towards enemies near it
 * : Enemies, items and even most bosses will be sucked to the single floating tear, dealing constant damage while keeping Isaac well away from harm, making this combination extremely effective in almost all scenarios.
 * : The tear becomes a large laser ring, which visually looks like a shot fired by . Shot speed is ignored. The Tears stat is ignored and damage is dealt very rapidly at a rate equivalent to 2 tear delay.
 * + : You have a ring of technology around you and you fire bombs normally.
 * : The tear explodes into six smaller tears, then reappears next to the player.

Interactions

 * / : The tear and familiar(s) travel together, as they are controlled in the same way. Because the familiars' travel speeds are not affected by Isaac's shot speed, they only travel in the same spot when Isaac has exactly the amount of shot speed to sync them up.
 * : Overridden by The Ludovico Technique.
 * : Overridden by The Ludovico Technique.
 * : No effect.
 * : Overrides The Ludovico Technique.
 * : Tear will alternate between "normal" and black. If it touches an enemy, it will stick to it, grow in size, then explode. The tear can not damage anything or be controlled when stuck to an enemy.
 * The tear will grow and explode very quickly when stuck to an enemy, instead of the normal Explosivo delay.
 * : Tears retain the ability to ignite enemies and explode. Tears respawn at Isaac's location after exploding.
 * : Fires created from Ghost Pepper will destroy the tear and cause it to respawn on Isaac.
 * Homing Tears: The tear slowly homes toward the nearest enemy. Once locked in an enemy moving the tear somewhere else becomes harder.
 * : Tear moves in a zig-zag pattern while controlled.
 * Invulnerability: Tear cannot be moved while in effect, but will still do damage.
 * : Overridden by The Ludovico Technique. (No damage increase or explosion.)
 * +4 damage bonus, no explosion.
 * : The Ludovico tear will sometimes shoot 4 smaller tears in each direction.
 * : The Ludovico tear will sometimes shoot smaller tears behind it.
 * : The tear becomes a controllable knife that deals double Isaac's damage. Effective shot speed is lowered. Tears stat is ignored and damage is dealt at a rate equivalent to 5 tear delay.
 * + : Replaces the Ludovico tear with Mom's Knife but removes the Godhead aura.
 * + : Creates an uncontrollable laser ring centered on Isaac. The knife becomes stuck under Isaac and cannot be fired.
 * : No effect.
 * An additional Ludovico tear is spawned when it passes through Multidimensional Baby, at the start of every room, and persists like the Ludovico tear itself. However, it cannot be controlled; it instead slowly follows Isaac.
 * : The Ludovico tear cannot be moved while Notched Axe is held up.
 * : The closer the tear floats to Isaac, the larger it is. The farther away, the smaller.
 * : Decreases the tear size by taking the form of a Pupula Duplex tear; however, it travels faster.
 * : The tear disappears upon contact with a flame created by the candle and reappears near Isaac, slightly shrinking the flame.
 * : The tear spins rapidly in small circles.
 * : The tear can occasionally stick to an enemy. If the enemy does not die quickly, the tear pops and a new one spawns.
 * : The tear controls as usual, and Isaac fires the laser towards the tear relative to his position, rather than in the direction the player is moving the tear.
 * + : Laser is fired directly at the tear while it is being moved, instead of being limited to cardinal directions.
 * : Overrides The Ludovico Technique.
 * : The tear controls as usual, and Isaac fires the laser towards the tear relative to his position, rather than in the direction the player is moving the tear. Technology 2's damage penalty still applies.
 * + : Laser is fired directly at the tear while it is being moved, instead of being limited to cardinal directions.
 * : The tear controls strangely. It orbits Isaac slowly when not controlled, and when controlled, the tear's movement is distorted. Additionally, the tear's range becomes limited to Tiny Planet's orbit distance.
 * : The Ludovico Technique overrides the beam's effect.
 * : The controls of the tear and the shield overlap, making it impossible to consistently control both.
 * : A smaller Ludovico tear will spawned and revolves round the main one. Also, the Ludovico tear now moves in a very unusual way, up is up-right, down is down-left, left is left-up, right is right-down. This can be counteracted by holding the keys or d-pad in its associated path (up-right to make it go up and so forth with the other keys).

Trivia

 * The Ludovico Technique is a reference to Anthony Burgess' novel A Clockwork Orange and Stanley Kubrick's film adaptation, where it was referred to as "Ludovico's Technique." The technique involved headgear which forced the patient's eyelids open (hence "Controlled Tears") while watching violent films under nausea-inducing drugs, conditioning them against violence.
