In-game Footage[]


  • 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 rested on his journey and had a dream; in the dream, he saw a ladder that served as the connection between Heaven and Earth.
  • This item's new effect closely resembles 15►120 Volt 120 Volt from Antibirth, which was added to the game with a different effect.
  • 15►The Stairway The Stairway was originally named Jacob's Ladder in Antibirth. It was renamed when being ported to avoid a naming conflict.
