A Blood Stone Chunk is a material in Bloodborne.
- A solid shard that forms in coldblood.
- After death, a substance in the blood hardens, and that which does not crystalize is called a blood stone.
- A chunk will never appear in the blood of an ordinary human. Seek deadlier foes if bloodstone chunks are needed.
Blood Stone Chunks are used to upgrade +6 weapons to +7 to +9. This can be done by choosing "Fortify Weapon" at the Workshop, in the Hunter's Dream.
