"This is an abnormal fascination with death and the dead, especially an erotic attraction to corpses. Due to this mental illness, the Debauchery (see Chap. 6: Soctalty) of this character increases to 100. Whenever a character is afflicted with necrophilia and close to a corpse, they must pass a Drive sub-ability check at TH 20 or be unable to resist their urge to copulate with the corpse."
