Bone Marrow Ash is a consumable item in Bloodborne.


In-Game Description

Additional medium that strengthens Quicksilver Bullets.
According to the workshop, this is a special bone marrow ash collected from Hemwick Charnel Lane.
Invaluable to hunters with weak bloodtinge who require the use of stronger firearms.



Imbues the user's Firearm with extra damage for the next shot only. Deals tremendous amounts of damage.

It lasts for a full minute, so players can choose carefully when they wish to fire the shot.


  • If players swap the firearm, the buff goes away, but if they transform their weapon, thus two-handing, then the effect remains.
  • It is already powerful enough in the hands of players with low Bloodtinge, but with high Bloodtinge levels it becomes extremely deadly.
  • Can also be used on the Cannon/Church Cannon, resulting in devastating damage.
  • Can also be used on the Flamesprayer/Rosmarinus. Its effect is much different on these firearms as the damage is increased, but the range and cone of fire is severely increased as well.


  • The description states that this item is produced in Hemwick Charnel Lane. Perhaps the entire area is dedicated to the burning of corpses as we can see multiple small structures, not large enough to live, but perhaps large enough to burn people, their smoke-pouring chimneys also hint at that.
  • Bone Marrow contain mostly hematopoietic stem cell.  Hematopoietic stem cells (HSCs) are the stem cells that give rise to all the other blood cells through the process of haematopoiesis. Bone marrow transplanation is most often performed for patients with certain cancers of the blood.
