Blood Dreg is a Consumable Item in Bloodborne.
|"The Vilebloods of Cainhurst, blood-lusting hunters, see these frightful things in coldblood.
They often appear in the blood of echo fiends, that is to say, the blood of hunters. Queen Annalise partakes in these blood dreg offerings, so that she may one day bear the Child of Blood, the next Vileblood heir."
- Received from killing hunters while in the Vileblood Covenant.
- NPCs will drop these as well but you must have the Corruption Rune equipped. (Confirmed on Djura)
- NPCs when killed in other Hunters' Worlds also count.
- They seem to have an extremely rare chance to drop from hunters inside Chalice Dungeons with the Corruption rune equipped.
- Used to increase covenant ranking by offering to Queen Annalise
- Using them from inventory will give Insight (+1) without adding rank in the covenant
- The blood dreg item looks suspiciously like sperm cells. Perhaps that is what Annalise, Queen of the Viledbloods needs in order to bear a child.
