Binding of Isaac: Rebirth Wiki

Swarmers float aimlessly around the room, occasionally spawning Attack FlyAttack Flies. When hit, they will spawn a PooterPooter, and when destroyed, they will spawn a Boom FlyBoom Fly. Swarmers do not deal contact damage.

Notes[ | ]

  • Collectible Skatole iconSkatole will charm a Swarmer. When charmed it won't spawn any Attack Flies until it is damaged. The Attack Flies that spawn will also be charmed.
  • The ring of Flies that surround the Swarmer is an indication of how much health it has. The Flies deplete as the Swarmer takes more damage.

Trivia[ | ]

  • Swarmers are the next and possibly the final stage of the original GaperGaper.[1]
  • As Swarmers have Champion forms it's possible to encounter a White Champion (though extremely rarely). This can be a challenging occurrence as the Swarmer will regain invincibility every time it takes damage due to spawning Pooters.
