Bone Marrow Ash is a Consumable Item in Bloodborne.

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."

Bone Marrow Ash Usage

  • Increases Quicksilver Bullet damage on the next shot only.
  • The buff can only be applied to left-handed firearms.
  • The buff lasts for 60 seconds after applied, or until the shot is fired.
  • The buff also ends if you swap out your left hand weapon after applying.




  • You may only carry 10 at a time.
  • Very high damage output can be achieved by parrying with the Reiterpallasch's special form and shooting after with a bone marrow ash imbued weapon.
  • Particularly effective against bosses with weak points that are normally out of reach of the player's melee attacks.
  • It takes a second to use this item (the Hunter enters a "loading the gun" animation). About the same time it takes to consume a Blood Vial.
  • The gun will give off grey smoke, indicating that it is loaded with the ash.
  • Just like with any enchant, switching the weapon will result in the buff disappearing.


Trivia goes here

      the riflemen in the forest before Hemwick Charnel Lane seem to drop this as a rare drop (whit item discovery of 280 was able to gain this but rarely thouh 2 in one drop)

      • Rom, the Vacuous Spider is not required05 Jul 2016 08:37  

        I've defeated only three Bosses but can already buy it. Killed Blood-starved Beast, Cleric Beast and Father Gascoigne. Have engaged Vicar Amelia but haven't defeated her. Either one of the defeated Bosses is the requirement, or it's something else, but Rom, the Vacuous Spider is incorrect.

        • Deadly effect?05 Jul 2016 08:37  

          Alright so I'm curious how this item works. Does it just give you like a status where no matter what the next shot uses the bone marrow ash. Oooorrrr, can you use it with a specific gun, change to your secondary and fire off without using that bone marrow ash. In a specific example in my head, you apply the bone marrow ash to your cannon, switch to pistol, fire off a counter-shot, then switch back to the cannon for like what 4X damage?

          • Requirement for this item:05 Jul 2016 08:37  

            To make this item available at the Hunter's Dream Messenger you need the Radiant Sword Hunter Badge (found at the top of the Healing Church Workshop).

            • I kind of like that this is needed to do significant damage with guns...05 Jul 2016 08:37  

              ...cause it sort of fits with the aesthetic. They had to manually load and ignite flintlocks and stuff around the time period this is based on. Even if you can "spam" shots (I just chalk it up to blood magic. lol), the only way you can actually legitimately fire a deadly gun shot is to manually load it with this item each time just like they had to back in the day. Sort of gives it flavor imo.

                Looks like some of his attacks once buff will deflect a buffed pistol shot, not sure if anyone else has had this happen, but just did while I was Beckoned to help.
