Bone Marrow Ash imbues the user's Firearm with a tremendous amount of extra damage, for its next shot only.

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, often one-shotting most low leveled players.
  • Can also be used on the Flamesprayer/Rosmarinus. Its effect is much different on these firearms, as not only the damage is increased, but the range and cone of fire is severely increased as well.
  • Bone Marrow Ash cannot be used on the Rifle Spear, Reiterpallasch, or Simon’s Bowblade, since it only applies to left handed weapons.


  • 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 contains 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.
