Undead Bone Shard is a Consumable in Dark Souls 3.

Undead Bone Shard

Undead bones that yet burn.

Cast it into the shrine bonfire to boost the recovery provided by the Estus Flask.

The bonfire's cinders are the bones of Undead, and a bone that still burns is a fresh cinder indeed. Before feeding upon death, one must first pray to it.


Undead Bone Shard Usage


Undead Bone Shard Locations

  1. Undead Settlement - Start near the Dilapidated Bridge bonfire near the white birch tree where the arrows fall if you haven't killed or befriended the giant, to the right of this tree is a platform you can jump to with the Undead Bone Shard on a dead body.
  2. Farron Keep - On the bottom of the tower to the right of the door with the three flames that you have to light. It is surrounded by a bunch of slugs. Video location (fextralife video starting at 1h 22m 27s)
  3. Cathedral of the Deep - Also near a white birch tree that the Giant shoots arrows around,  on the roof area of the Cathedral after navigating the graveyard and crossing a bridge.
  4. Catacombs of Carthus - Kill the skeleton with a hat at the bottom of the long stairs, near the first Skeleton Ball, to break the ball and reveal a shard.
  5. Smouldering Lake - Kill the Carthus Sandworm.
  6. Smouldering Lake - From the Demon Ruins bonfire. Head down the stairs into the long room filled with floating fireballs and demons. Head left towards the end of the room. The boneshard is located with bodies of dead demons. Below a Fire Slime that attemps to fall ontop of you. (Video)
  7. Irithyll of the Boreal Valley - Starting at the Church of Yorshka bonfire, go down the hallway stairs, and go right along the cliff. The Undead Bone shard is located behind the large tombstone at the end of this path (Video)
  8. Profaned Capital - After you fight the first Gargoyle of the area, it will be on a corpse right next to the bonfire.
  9. Lothric Castle - Starting at the Dragon Barracks bonfire, go up the stairs and to the bridge where the two dragons are. Run almost all the way across the bridge and drop off at the end. The Undead Bone Shard is underneath the bridge.
  10. Grand Archives - In the area of the rooftops where you fight some Gargoyles, there will be a broken window that you can enter. The shard will be in this room.

      the location for the grand archives could be more clear; spent 20 minutes running all over the rooftops trying to figure out where this secret 'room' was before finally searching video and realizing the shard is on the chair on the walkway above the second(?) big group of wax-head dudes hanging around all those bookshelves and can be way more easily reached from the elevator right next to the grand archives bonfire if you've unlocked it already.

          Unless I have forgotten how to read, Prima's guide doesn't mention the Shard located inside one of the Skele-balls in the catacombs.<br/><br/>So, for all of you unable to find your tenth shard - and came here, like I did - that is the one you're missing.

            I accidentally spill a bucket of tears on my bonfire and put it out. Does anyone know how I can re-light it?

              Do these re-appear in NG+? I want to be able to get every item and have my bonfire maxed, and I don't want to have to sacrifice estus power to get the shield

                @ first comment, you get the shield if you trade in 1 shard , not the shard if you trade the shield

                  I thought I picked all the shards up, I even re-checked the spots a few times, but my bonefire is still at +10 and I dont have any shards to burn.

                    I just tested the +0 and +1 flasks, and got 250 / 335 points of healing respectively. I was not using the Estus Ring. Those values are already on the table for higher level flasks. I think that data must be wrong. PC, v1.07.

                      The profaned capitol shard...24 May 2016 03:18  

                      Is right next to the bonfire (literally). I feel that's a better explanation than "After the first gargoyle on an corpse nearby."
