• Disease (Ex): The rotting bodies of Carrion Pigeons are infested with a wide-range of bacteria that can cause diseases in the living. Any creature that comes into contact with a Carrion Pigeon must make a Fortitude save (DC11) to avoid contracting an illness of the DM's choice.
- OR - Zombie Virus (Ex): A target injured by a Carrion Pigeon, or one that eats a Carrion Pigeon or drinks water contaminated by its body, must make a Fort save (DC11) or contract a Zombie Virus. Onset time: 1d4 hours, Damage: 1 Con/hour, if a target is reduced to 0 Constitution, it dies and rises as a zombie who can then transmit this virus to its victims in turn. This disease can be cured with a Remove Disease or Heal spell.
