Larval Infection (Ex) Special—contact; save Fort 12, frequency 1 day, effect 1d3 Con and 1d3 Wis damage, cure 2 consecutive saves that exceeded the DC by 5 or more. As a full-round action, usually during an act of passion, a hirudophagus can infect a humanoid or a humanoid-blooded native outsider with one of its larvas. The larva slowly consumes the victim's intestines, with only a minimal disturbance to the victim, due to the larva's anesthetic excretions. When Constitution damage exceed the victim's Constitution score, the parasite takes over the body turning the victim into another hirudophagus. If Wisdom damage exceed the victim's Wisdom score before transformation, the infected becomes restlessly amorous and lustful, eschewing rest and personal care until the infection is cured or the transformation occurs. This is a disease effect and can be treated accordingly. A hirudophagus can infect 1d3+1 victims before dying and needs at least hour after an infection before it can infect another victim.
Scent of Prey (Ex) A hirudophagus has a scent special ability though restricted only to humanoids and humanoid-blooded native outsiders, such as aasimars or tieflings. It also allows hirudophagus to recognize and avoid creatures already infected by hirudophage larva.
Hirudophages are leech-like parasite that eat guts of their hosts, wearing infected bodies like sophisticated disguises to spread among humanoids. Being only marginally stronger and resistant than average humanoid, hirudophages are naturally cunning, trying to entice unsuspecting victims into entering intimate contact, though they retain only minimal level of intelligence and capability to use language of their host.
The exact source of hirudophage is unknown, with outbreaks of infection appearing in various place from time to time, as if a smart, long-living carriers capable of overcoming their lust were moving across population centers.
