Added in Afterbirth

Maw of the Void is an unlockable passive item added in The Binding of Isaac: Afterbirth.

Effects[]

  • Removed in Repentance +1.0 damage.
  • After firing tears for 2.35 seconds, releasing the fire button unleashes a black Brimstone Brimstone ring around Isaac that expands and contracts, dealing damage at a rapid rate to all enemies touching it.
    • The charge is completed when a red upside-down cross appears on Isaac's forehead.
    • Added in Afterbirth † With charge bars enabled, there is also an indicator that displays the charge.
    • The black ring deals damage equal to Isaac's current damage per tick, and ticks a total of 30 times. It lasts ~1.97 seconds (118 frames).
    • Removed in Repentance Enemies killed by the black ring have a 5% chance to drop Black Hearts.
      • Black Hearts will drop as soon as the enemy is killed. (In other words, the heart will drop at the beginning of the death animation rather than at the end of the death animation.)
  • This item belongs to the Leviathan set. Collecting three items from this set will transform Isaac into Leviathan.

Notes[]

  • Removed in Repentance This item does not work while playing a blindfolded character, as it requires tears to charge.
    • This restriction can, however, be bypassed by picking up The Ludovico Technique The Ludovico Technique.
    • This item's effect will not fully activate if picked up by Lilith Lilith; its stat ups will still apply to her Incubus Incubus familiar, but the ring will not appear unless she also has the Ludovico Technique.
  • Added in Repentance This item will still work while playing as a blindfolded character.
  • The ring will apply any tear status effects such as poison if Isaac has them.

Synergies[]

  • Guppy: Damaging enemies with Maw of the Void allows flies to spawn from the Guppy transformation. Flies are spawned at a rate of approximately one fly per tick of damage for each enemy it hits. This causes a lot of flies to spawn very quickly. The spawned flies will also move to attack the nearest enemy immediately.
  • Homing tears: The ring curves towards enemies.
  • Ipecac Ipecac: Massively increases ring damage and poisons enemies.
    • Added in Repentance The ring also explodes on enemy or obstacle contact.
  • Added in RepentanceJacob's Ladder Jacob's Ladder: The ring sends out electric currents when it hits something.
  • Lost Contact Lost Contact: Ring can destroy projectiles.
  • Mysterious Liquid Mysterious Liquid: Occasionally spawns a pool of creep where the ring makes contact with an enemy.
  • Pisces Pisces/8 Inch Nails 8 Inch Nails: Ring obtains knockback effect.
  • Removed in Afterbirth † Proptosis Proptosis: The ring is much larger and deals 1.5x damage per tick.
    • Added in Afterbirth † / Removed in Repentance The ring is larger but deals normal damage.
    • Added in Repentance No effect.
  • Strange Attractor Strange Attractor: Ring attracts pickups and enemies towards it.
  • Wiggle Worm Wiggle Worm: The ring has wavy edges.

Interactions[]

In-game Footage[]

Trivia[]

  • Maw of the Void has a unique charge bar, filling with red instead of the usual green, as well as having a small swirl reminiscent of its shape in the middle of it.

Bugs[]

Bug Bug! Added in Repentance When combined with Chocolate Milk Chocolate Milk, Cursed Eye Cursed Eye, Monstro's Lung Monstro's Lung or Tech X Tech X, releasing a Maw of the Void attack may prevent a charged shot from firing at the same time as expected. The charged shot is delayed by about ~0.5 seconds. Holding a full charge for a longer time makes the delay more likely to happen.
