The Parasite is an unlockable passive item.

Effect

• Tears split into two tears on impact with obstacles or enemies.
  • The split tears deal 50% of Isaac's normal tear damage.
  • If one of those split tears hits an obstacle or enemy, it will split again and deal 25% of Isaac's normal tear damage.

Synergies

• Angelic Prism: All tears split by the prism will burst into split tears when hitting obstacles.
• Compound Fracture: Both tear split effects happen simultaneously.
• Continuum/Spectral Tears: When tears pass through solid objects, like rocks, they will split, resulting in many tears shooting out from every rock the original tear passed through.
• Cricket's Body: Two groups of this item's four tears, creating eight additional miniature tears on every point of impact instead.
• Dr. Fetus: Bombs split into two bombs upon detonation.
• Flat Stone: Every time tears bounce, burst tears spawn.
• Lachryphagy: Fed tears split into 12 tears. When tears are minimally fed and hit an obstacle, they will split into 5 Lachryphagy burst tears and Parasite burst tears.
• Lead Pencil/Monstro's Lung: All tears in tear barrage will burst into split tears when hitting obstacles or enemies.
• The Ludovico Technique: Repeatedly spawns miniature tears when on top of an enemy, greatly increasing damage.
• Piercing Tears: Split tears form for each hit as the tears pass through the enemies.
• Sad Bombs: After bombs explode, all tears burst into split tears if they hit obstacles.
• Spectral Tears: Split tears form continuously when tears hit obstacles.
• Tiny Planet: The split tears will continue to orbit Isaac, increasing damage potential.
• Tractor Beam: The split tears will be forced directly forward, impacting whatever caused the first tear to split. This increases damage immensely.
• Trisagion: When beams hit obstacles, the beam will split; the split beams can split again when hitting other obstacles.

Interactions

• Bob's Rotten Head: Two further explosions appear perpendicular to the head's direction of travel when it blows up.
• Brimstone: Overrides The Parasite.
• Diplopia: No effect.
• Dr. Fetus: Bombs turn orange and with no other effect.
• Epic Fetus: Overrides The Parasite.
• Ipecac: The Ipecac tear will spawn two smaller explosive tears when it collides with a solid object, but not with an enemy. These tears can spawn tears on their own as well, potentially leading to huge chain reactions. Having Host Hat or Pyromaniac is strongly recommended.
• Kidney Stone: Drastically decreases range making it less likely for tears to split. The stone will not split.
• Mom's Knife: Knife turns orange with no other effect.
• Rubber Cement: Tears only split when hitting enemies and no longer off the wall or most obstacles.
• Technology: Overrides The Parasite.
• Tech X: Overrides The Parasite.
