Effects[edit | edit source]

  • Tears travel in a large spiral pattern.
  • Grants spectral tears.
  • +4.0 range.
  • +2.0 tear height.
  • A luck-based chance for a homing shot, reaching 100% at 9 luck.
    • The homing shots are not different in appearance.
    • The homing does not override the spiral pattern, making them still unreliable.

Synergies[edit | edit source]

  • 15►Dr. Fetus Dr. Fetus: Since the bombs don't follow the spiral pattern, only the extra range, spectral bombs, and chance for a homing bomb apply.
  • 15►Tractor Beam Tractor Beam: The tears follow a straight path, ignoring the spiral pattern, the tears also stall at a specific point giving a greater chance to land tears.

Interactions[edit | edit source]

  • Azazel: Increases the range of his short-ranged Brimstone. No homing chance.
  • 15►Brimstone Brimstone: Overrides Ouroboros Worm.
  • 15►The Ludovico Technique The Ludovico Technique: The tear spirals around in a difficult to control manner, with the added homing chance further complicating things.
  • 15►Mom's Knife Mom's Knife: Overrides Ouroboros Worm.
  • 15►Tech X Tech X: Overrides Ouroboros Worm.
  • 15►Technology Technology: Grants spectral tears without a change in pattern or a chance of homing shots.
