Vampire Blood effects on Mortal creatures have several effects, which can be interesting.
Bonding If the user drinks fresh blood from a vampire, a psychic and emotional bond is created. The human will become sexually attracted to and have sexual dreams about the vampire. The vampire, in turn, will be able to sense the location, emotions and state of the human. This effect lasts for days.
Enhanced Abilities The user will experience enhanced strength, senses, aggression, and libido, which will last as long as the blood is in their system.
Drug Qualities The user may experience hallucinations, which vary from person to person.
Healing A human or supernatural creature that ingests vampire blood will be able to heal wounds at an accelerated rate.
Withdrawal Symptoms If the user is addicted to vampire blood and stops ingesting it, they will experience withdrawal symptoms, which are similar to those of heroin withdrawal (such as tremors, cramps, muscle and bone pain, perspiration, tachycardia, etc).
