Pointy Rib is an unlockable passive item added in The Binding of Isaac: Afterbirth † (Booster Pack #5).
Effects[ | ]
- Spawns a bone familiar that can be aimed with the fire buttons in all directions and does contact damage.
- The familiar will continuously hover back and forth in the direction that it is pointing in.
- The damage is equal to Isaac's tear damage and is dealt 6 times per second.
- The damage increases when Isaac is moving on the direction the familiar is pointing in based on Isaac's current speed, up to twice of its base damage.
- The familiar will damage Poops and Fire Places.
Synergies[ | ]
- Proptosis: Triples the contact damage. Has no penalty with range.
Interactions[ | ]
- BFFS!: Doubles the base contact damage, but not the bonus damage granted from Isaac's movement.

Trivia[ | ]
- The item is possibly a reference to the Genesis story where God created Eve by removing a rib from Adam.
