Ouroboros Worm is a trinket added in The Binding of Isaac: Afterbirth †.

Effects

• Tears travel in a large spiral pattern.
• Grants spectral tears.
• +4.0 range.
  • +1.5 range, +0.4 tears.
• +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

• Aquarius: Creep has a chance to be homing.

• Dr. Fetus: Since the bombs don't follow the spiral pattern, only the extra range, spectral bombs, and chance for a homing bomb apply.
• 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

• Azazel: Increases the range of his short-ranged Brimstone. No homing chance.
  • His Brimstone now spins.
• Brimstone: Overrides Ouroboros Worm.
  • The Brimstone laser is shot in a spiral pattern. Homing does take effect, but is hardly noticeable.
• The Ludovico Technique: The tear spirals around in a difficult to control manner, with the added homing chance further complicating things.
• Mom's Knife: Overrides Ouroboros Worm.
  • Works as intended. The homing, however, is questionable.
• Proptosis: The curious pattern allows dealing full damage from a safer range.
• Tainted Azazel: His Brimstone laser is shot in a spiral pattern. Homing does take effect, but is hardly noticeable.
• Tech X: Overrides Ouroboros Worm.
  • Tech X now inherits the homing chance benefit, without being affected by the pattern.
• Technology: Grants spectral tears without a change in pattern or a chance of homing shots.
  • The tech laser is now affected by the pattern. The homing DOES take affect, but it's fairly hard to notice.

Trivia

• This trinket is a reference to Øuroboros, which was a prototype of the game "The End is Nigh" by Edmund McMillen and Tyler Glaiel.
• The Ouroboros is an ancient symbol, showing a serpent or dragon eating its tail.
