Zombies have a minimum of 1 in any physical attribute and have the same amount of Stamina as they did in life. They do not use coordinated attacks or pack strategy, they just mill around and swarm anything that looks alive. An outbreak of the zombie radiation in the World of Darkness may not be as disasterous with the supernatural elements able to fight the creatures. However, the odds are still in favor of the living dead. The living dead will tear into a vampire as readily as a human, much to the surprise and ultimate demise of the Kindred.
Vampire blood has no effect on the living dead.
Ghouls are seen as food as well, and a ghoul who is bitten will become a living dead just like a normal person. Once this occurs, all ghoul powers are lost. Vampire blood will not heal the infection. A vampire who is bitten will not die, but he is now a carrier and will turn anyone he bites into one of the walking dead. A were-creature who is bitten may not die, depending on its abilities to fight off disease.
