Parasitoid is a passive item added in Afterbirth †.

Effects

• Adds a chance to fire an egg sack which spawns slowing creep. If an egg sack hits an enemy, a blue fly or blue spider is spawned.
• Egg sack tears have considerably higher tear height and consequently, range.

Notes

• Egg sacks will also spawn blue flies or spiders if they hit fireplaces or invincible enemies like Death's Head and Stoney.
• The chance to fire an egg sack is affected by luck. It is 15% at base luck (0) but cannot reach 100% at high luck.

Synergies

• Compound Fracture / Cricket's Body / The Parasite: When egg sacks are fired, they will split into smaller egg sacks. Split egg sacks from The Parasite will not look like egg sacks.
• Cupid's Arrow: Egg sacks will apply their effect to every enemy hit.
• Hive Mind: Flies and spiders are bigger and deal double damage.
