Binding of Isaac: Rebirth Wiki

Added in Repentance

Larynx is an unlockable activated item added in The Binding of Isaac: Repentance.


  • Isaac shouts, damaging and pushing away nearby enemies.
    • The item can be used when not fully charged, but deals more damage and has increased range the more charges it has when used.
    • The damage the shout deals is 20 + 28 per charge used.
      • The shout also deals extra ticks of damage to enemies that are close enough. These extra ticks deal damage equal to 2.5 + 3.5 per charge used, and can tick a number of times up to half the charges used (rounding up).
        • The range of the extra ticks also varies depending on the charges used: enemies that are closer to Isaac will receive more ticks of damage.
    • The shout is able to destroy obstacles, such as rocks, Poop Poops and Fire Place Fire Places and open bombable doors, including Bedroom and Secret Room Secret Room doors.
  • Larynx gains 1 charge whenever Isaac takes damage, as well as through normal means.


  • The Battery The Battery: Larynx can hold up to two full charges. Only up to 12 charges will be used at a time.
  • Book of Virtues Book of Virtues: Spawns red wisps on the middle ring. The wisps deals contact damage equal to 30% of Isaac's damage * Charges Used. Charges Used equals the number of charges Larynx had at the time it was used. Health = 1 * Charges Used. Tear Damage = 1.5 * Charges Used.
  • Habit Habit: Both on-hit charge effects stack, charging 2 points per hit.
  • Hairpin Hairpin: Fully recharges Larynx at the beginning of boss fights, giving Isaac a way to easily devastate several bosses.


  • 9 Volt 9 Volt: The first bar gains an automatic recharge, but the further bars will not be affected.
  • Void Void: Very poor combination. Absorbing Larynx and using it through Void will cause Isaac to only perform the 1-charge version regardless of how many times he has taken damage or how many charges Void has, resulting in minimal damage.
