Binding of Isaac: Rebirth Wiki

Disambig.png This article is about the item. For the enemy, see Mulligan.

The Mulligan is a passive item.


  • Tears have a 1/6 chance of spawning allied Blue Flies when they hit an enemy.
  • This item belongs to the Beelzebub set. Collecting three items from this set will transform Isaac into a giant humanoid fly.


  • Removed in Repentance Because the Guppy transformation includes the guaranteed ability to spawn flies on hit, the Mulligan's effect is nullified. This means individual tears cannot spawn more than one fly per hit.
    • Added in Repentance Guppy has been lowered to have a 50% chance of spawning a fly, allowing the 2 items to work together.
  • Removed in Repentance This item does not work for Lilith Lilith since the Added in AfterbirthIncubus Incubus tears do not count for her tears.
  • Items and trinkets that increase tear firing rate synergize well with the Mulligan.
  • This item is not affected by luck.


  • Brimstone Brimstone: Constantly spawns blue flies when attacking.
  • Chocolate Milk Chocolate Milk: The Mulligan's ability isn't affected by the charge time, meaning rapidly firing uncharged shots will generate a ton of blue flies.
  • Cricket's Body Cricket's Body / The Parasite The Parasite: Has a 1/6 chance to spawn a fly on every hit by a split shot, which boosts the spawning of flies immensely.
  • Added in Afterbirth †Finger! Finger!: Rapidly spawns blue flies when pointed at an enemy.


  • Azazel Azazel: Azazel's default brimstone spawns flies like regular tears.
  • Epic Fetus Epic Fetus: Overrides The Mulligan.
  • Mom's Knife Mom's Knife: Flies only have a chance to spawn if the knife is stationary.
