Effects[edit | edit source]

  • Tears fire 1-2 sparks of electricity in random directions upon hitting an obstacle or enemy.
    • Sparks deal half of the tear's damage (Isaac's current damage stat).
    • Sparks behave like spectral homing lasers and will arc to hit enemies that are close enough, even striking multiple ones in a row.
    • Tears that hit the floor due to running out of range do not generate arcs.
  • Added in Repentance Only one electric arc happens, and they have a very short range compared with before. However, when an arc strikes an enemy, it will strike another nearby enemy with a new spark, creating a chain of sparks up to 4 more targets.

Synergies[edit | edit source]

  • All status causing tear effects: The status effects will be applied over the electric arcs as well. The poison caused by 15►Serpent's Kiss Serpent's Kiss will not drop black hearts.
    • Sinus Infection / Nose Goblin: A booger tear that strikes an enemy will also apply a booger to each enemy that gets hit by an electric arc.
  • 15►Angelic Prism Angelic Prism: All of the split tears will be electrified. Also, electric arcs that pass through the prism will be split.
  • 15►Lost Contact Lost Contact: Tears block enemy shots as normal and will then generate arcs of electricity where the shot was blocked.

In-game Footage[edit | edit source]

Trivia[edit | edit source]

  • 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.
    • The name 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 that serves as the connection between Heaven and Earth.
  • Added in Repentance This item's new effect closely resembles Added in Repentance15►120 Volt 120 Volt from Antibirth, which was added to the game with a different effect.
