Polished Bone is an unlockable trinket added in The Binding of Isaac: Repentance.
Effects[ | ]
Interactions[ | ]
- Ace Cards: Friendly monsters are still affected by Ace Cards.
- Blood Puppy: Either angry version of Blood Puppy will target friendly enemies as well and can drag them along with it when it charges them. Blood Puppy cannot damage friendly enemies however friendly enemies can damage Blood Puppy despite not targeting it outright.
- Broken Modem: Broken Modem also affects friendly enemies and projectiles created by them.
- Eraser: Bonies erased by Eraser will never spawn again, greatly diminishing the value of Polished Bone. If Black Bonies are also erased, Polished Bone becomes useless.
- Ghost Bombs / Hungry Soul / Purgatory / Vade Retro: Explosions from ghosts can kill friendly enemies.
- Glowing Hourglass: Each use of Glowing Hourglass that does not move Isaac to a different room than the one he is currently in (such as the starting room of a new floor) will duplicate friendly enemies. (This is possibly a bug)
Trivia[ | ]
- The namesake of this item most likely comes from the fact that "polishing one's bone" is sexual innuendo for male masturbation.
- This is furthered by the fact that the item has a rather phallic shape and nature to it.
