Blood Gem Imprints are part of Bloodborne's advanced weapon upgrades.

Each weapon comes with Blood Gem Imprints, which acts as infusion slots. Trick Weapons usually have 3 slots, while Firearms mostly have 1 slot.

  • Imprints decide which shape of Blood Gems the weapon can be infused with, but Droplet shaped Blood Gems will fit into any slot.
  • Imprints are unlocked by fortifying the weapon. Fortify to +1 unlocks the 1st slot, +3 the 2nd slot, and +6 the 3rd slot.
  • Most Trick Weapons also comes in 3 different varieties; Normal, Uncanny and Lost. The Uncanny and Lost versions are found in Chalice Dungeons, and the only difference between them are the Imprint slot shapes.
  • Generally speaking, all types of right-hand weapon gems share from a loot table of similar possible effects. Without farming gems, frequency patterns of stat boosts versus attack-type modifications can be seen through collecting during normal play.

      My question is how much does the elemental gems effect scaling. Does it make make going over the base required stats redundant in other words with arcane on the weapon shown would it be better to just have 16 str 12 skill and then pump 40-50 arcane. Also how would it effect the scaling of weapons that already have the elemental damage effects? ex. Blades of Mercy, Chikage. I would test these things out myself but i have been having bad luck on getting worthwhile elemental gems.

        This image is misleading... Since the player has not equipped the fire stone yet, the damage shown is not accurate, once equipping a fire stone all physical damage becomes fire, and scaling for that weapon changes.
