Binding of Isaac: Rebirth Wiki

(in Afterbirth † and Repentance)

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

Effects[]

  • Tears travel in a large spiral pattern.
  • Grants spectral tears.
  • (except in Repentance) +4.0 range, +2.0 tear falling speed.
  • (in Repentance) +1.5 range, +0.4 tears.
  • 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, meaning tears stay unreliable.

Notes[]

  • (in Repentance) While in the Mirrored World, the spiral pattern will also be mirrored.

Synergies[]

  • (in Repentance) Golden Trinket Golden Trinket / Mom's Box: The spiral pattern is larger, tears travel faster and the stats increases are doubled.
  • (in Repentance) 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[]

  • (except in Repentance) Azazel / Brimstone / Technology / Technology 2: The spiral effect is overidden. All other effects still apply.
    • (in Repentance) The 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.
  • (except in Repentance) Mom's Knife: Overrides Ouroboros Worm.
    • (in Repentance) 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.
  • (except in Repentance) Tech X: Overrides Ouroboros Worm.
    • (in Repentance) Tech X now inherits the homing chance benefit, without being affected by the pattern.

Trivia[]

  • The Ouroboros is an ancient symbol, showing a serpent or dragon eating its tail.
