Ouroboros Worm

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

Effects

 * Tears travel in a large spiral pattern.
 * Grants spectral tears.
 * +4.0 range.
 * +1.5 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

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

 * Increases the range of his short-ranged Brimstone. No homing chance.
 * : Overrides Ouroboros Worm.
 * The Brimstone laser is shot in a spiral pattern.
 * : The tear spirals around in a difficult to control manner, with the added homing chance further complicating things.
 * Overrides Ouroboros Worm.
 * Works as intended. The homing, however, is questionable.
 * : The curious pattern allows dealing full damage from a safer range.
 * Overrides Ouroboros Worm.
 * Tech X now inherits the homing chance benefit, without being affected by the pattern.
 * 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.
