Brittle Bones is an unlockable passive item added in The Binding of Isaac: Afterbirth †.

Effects

• Grants 6 empty Bone Hearts.
• Removes all Red Heart containers. Does not remove existing Bone Hearts, but does empty them.
• Upon losing a Bone Heart, including ones acquired from other sources, Isaac fires a ring of 8 bones that split into more bones and permanently gains a +0.5 tears up.
  • Each bone does twice Isaac's damage plus a flat 22 damage; split bones do half this amount.

Notes

• Picking this item up as The Lost or Keeper will give a one-time +0.5 tears up. This bonus is retained even if the item is later lost or rerolled.
  • Keeper will also gain 24 Blue Flies.
• The tears up bonuses gained through this item will persist in the escape sequence of Mines II.

Synergies

• Empty Vessel: The empty Bone Hearts will trigger Empty Vessel's effects.

Trivia

• Brittle Bones has been added in Booster Pack #5, after the initial release of the DLC.
• "Everything hurts" may be a reference to Melting from Nuclear Throne.
