The Parasite

Effects

• Tears that deal more than 1.0 damage split into two tears with half damage and half remaining range on impact with obstacles or enemies.
  • Damage less than 1.0 causes the tears to simply disappear.
  • The splitting can keep up as long as the tears have range remaining and the damage of the split tears stays above 0.5.
  • Split tears are scaled down by 0.5x from the parent one, ignoring damage based size reduction.

Synergies

• (Added in Afterbirth †) Angelic Prism: All tears split by the prism will burst into split tears when hitting obstacles.
• Bob's Rotten Head: Two further explosions appear perpendicular to the head's direction of travel when it blows up.
• (Added in Repentance) C Section: Fetuses fire short-ranged tears constantly while in contact with an enemy.
• (Added in Afterbirth †) Compound Fracture: Both tear split effects happen simultaneously.
• (Added in Afterbirth) 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.
• (Added in Afterbirth †) Flat Stone: Every time tears bounce, burst tears spawn.
• (Added in Afterbirth †) 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.
• (Added in Afterbirth †) 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.
• Tiny Planet: The split tears will continue to orbit Isaac, increasing damage potential.
• (Added in Afterbirth) Tractor Beam: The split tears will be forced directly forward, impacting whatever caused the first tear to split. This increases damage immensely.
  • If all shots connect, effective damage will be multiplied by 2 + log2(damage).
• (Added in Afterbirth †) Trisagion: When beams hit obstacles, the beam will split; the split beams can split again when hitting other obstacles.

Interactions

• Aquarius: No effect.

  • (Added in Repentance) Creep trail turns dark orange but doesn't affect the creep itself.

• (Removed in Repentance) Brimstone: Overrides The Parasite.

  • (Added in Repentance) 2 beams will be fired perpendicular to the main beam at the closest point of intersection with an enemy or obstacle.

• (Added in Afterbirth) Diplopia: No effect.

• (Removed in Afterbirth) Dr. Fetus: Bombs turn orange and with no other effect.

  • (Added in Afterbirth) Dr. Fetus: Bombs split into two bombs upon detonation.
    • +(Added in Repentance) Rocket in a Jar: Rockets split into two bombs (not rockets) upon detonation.

• Epic Fetus: Overrides The Parasite.

• (Added in Repentance) Eye of the Occult: Split tears can be controlled similarly to normal tears, which results in a large amount of floating tears.

• 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 (Added in Afterbirth) Host Hat or Pyromaniac is strongly recommended.

• (Added in Afterbirth) Kidney Stone: Drastically decreases range making it less likely for tears to split. The stone will not split.

  • (Added in Repentance) Laser splits into two perpendicular beams upon hitting an obstacle.

• (Added in Afterbirth) Tech X: Overrides The Parasite. Laser rings become orange.
