Binding of Isaac: Rebirth Wiki

(in Repentance)

Bone Spurs is an unlockable passive item added in The Binding of Isaac: Repentance.

Effects[ | ]

  • Enemies spawn 1-2 floating bones on death, which block enemy shots and damage/repel enemies that touch them.
    • Bones block 2 shots and/or deals 2 ticks of damage before breaking.
    • Bones deal contact damage equal to Isaac's damage in the moment they were created.

Notes[ | ]

  • Bone particles will be created whenever Isaac shoots, though this is purely visual.
  • Because the bones deal contact damage equal to Isaac's damage in the moment they were created, if the damage stat was changed, the bones that were already present on the screen will use Isaac's old damage stat.

Synergies[ | ]

  • Collectible BFFS! iconBFFS!: Doubles the bones' size and damage.
  • Collectible Spin to Win iconSpin to Win: Boosts the bones' damage while spinning even though there's no visual tell of the effect.
