Jacob's Ladder

Jacob's Ladder is a passive item added in Afterbirth †.

Effects

 * Tears fire 1-2 sparks of electricity in random directions upon hitting an obstacle or enemy.
 * Sparks deal half of Isaac's tear damage.
 * Sparks have a chance to arc and hit multiple enemies.
 * Tears that hit the floor due to running out of range do not generate arcs.

Synergies

 * Homing tears: Enemies are more likely to be hit by both sparks and tears.
 * Ipecac: Electric arcs happen normally and gain benefit from Ipecac's high base damage.
 * The Ludovico Technique: The Ludovico tear spawns a large number of sparks when in contact with an enemy.
 * The Ludovico Technique+Monstro's Lung: Lightning is spawned by all the tears in the cluster but also will damage Isaac.
 * The Ludovico Technique+Conjoined (Transformation): Lightning is spawned by all three tears but also will damage Isaac.
 * The Parasite: Additional tears caused by The Parasite also create arcs of electricity.
 * Serpent's Kiss: Sparks sometimes poison enemies and generate black hearts.
 * Mom's Perfume: Sparks caused by a perfume shot that arc to other enemies have a chance to cause the fear effect.

Interactions

 * Brimstone / Azazel: Overrides Jacob's Ladder.
 * Evil Eye: Sparks created by Evil Eye's tears will hurt Isaac.
 * Mom's Knife: Overrides Jacob's Ladder.
 * Spectral Tears: Spectral tears make Jacob's Ladder spawn electricity for every obstacle the tears go through. Electricity does not spawn when tears go through room walls.
 * Rubber Cement: Tears bouncing off of obstacles will not spawn sparks; thus, only collision with enemies will trigger it.
 * Soy Milk: Spawns sparks of electricity rapidly, but the sparks will deal very little damage.
 * Tech X: Overrides Jacob's Ladder.
 * Technology: Overrides Jacob's Ladder.
 * Dr. Fetus / Epic Fetus: Overrides Jacob's Ladder. Bombs do not generate sparks of electricity.

Trivia

 * Jacob's Ladder is a reference to The Book Of Genesis from the Old Testament. In Genesis 28:10-19 Jacob rests on his journey and has a dream; in the dream he sees a ladder which serves as the connection between Heaven and Earth.
 * This item may also be a reference to the psychological horror movie of the same name, in which a man is tormented by hallucinations and can't make out what's real and what isn't.
 * This item refers to high voltage traveling arcs, which are colloquially known as Jacob's ladders. It creates a small electric arc rising between two metal rods, as the item graphic represents.
