Donkey Jawbone Defeat The Witness as Samson.

Donkey Jawbone is a passive item.


  • When Isaac takes damage, a spin attack will damage enemies around him, doing his current damage with a multiplier.
    • The spin attack blocks projectiles.
    • When an enemy is killed with the spin attack, it has a chance to drop a red heart on the floor.


  • 20/20: Grants 1 additional spin.
  • Ipecac: Spin attack poisons enemies.
  • Menorah: Upon taking damage, Menorah's multiplier is incremented before increasing the number of spins accordingly.
  • Mom's Knife: The jawbone is thrown forwards in the air and spins several times before returning to Isaac.
  • Mutant Spider: Grants 3 additional spins.
  • The Inner Eye: Grants 2 additional spins.
  • Uranus: Enemies killed by the spin attack are frozen. Heart pickups from Donkey Jawbone's effect drop when a frozen enemy shatters.

In-game Footage


  • This item is a reference to a passage from the Book of Judges in which Samson kills one thousand Philistines using only the jawbone of a donkey.
  • This item originated from the Binding of Isaac: Community Remix mod.
    • In the Binding of Isaac: Community Remix, this item was similar to Mom's Knife. It was changed to the way it is now due to Samson's changes in Rebirth.
