That arrow's soaked in dead man's blood. It's like poison to you, isn't it?

Dead man's blood is a substance that is like poison to vampires, which is blood from dead people. This is an essential tool when hunting vampires, as it can create enough pain to incapacitate a vampire and in some cases, knock them unconscious.


Once in the vampire's system they can no longer move and lose all their strength. It also hurts them, which is why Gordon Walker uses it to torture Lenore.

Some vampires are rendered unconscious by dead man's blood with it acting like a sedative to them. This appears to depend on the amount of dead man's blood they are given and possibly the vampire's age.

When Celia was injected with dead man's blood, the veins on the right side of her face become prominent and her right eye began to become bloodshot.

When a person is turned into a vampire, injected with dead man's blood and then cured, they appear to suffer no ill effects from the dead man's blood afterwards.
