Wraith: The Oblivion uses White Wolf's
Storyteller System. As in all Storyteller System games, there are several special rules and systems that support the theme of the game. The most notable are: ;Pathos :Pathos is an emotional energy that the Wraith is able to draw from their Passions. They can use this to power their various Arcanoi abilities, to resist their Shadow, and to heal their Corpus. ;Corpus (Health) :As the characters are already dead, they do not necessarily sustain physical damage from attacks. Instead, they have a rating score called Corpus which measures their ability to maintain physical integrity. When Corpus falls to zero, a wraith may undergo a Harrowing, a nightmarish psychodrama which pits the wraith against their Shadow in a battle for control. ;Arcanoi :Arcanoi, the magical abilities Wraiths can use, are open to most of them, with members of secret groups called Guilds specializing in their use. Although membership within a Guild is outlawed by the oppressive Hierarchy, they still exist in secret and are playable options within the game. The Arcanoi and their respective Guilds are: •
Inhabit: the art of possessing inanimate objects, a skill of the Artificers' Guild. •
Keening: the art of inducing emotion through song, a skill of the Chanteurs' Guild. •
Argos: the art of Underworld travel, especially in the Tempest, a skill of the Harbingers' Guild. •
Pandemonium: the art of causing chaos in the traditional "ghostly" manner, a skill of the Haunters' Guild. •
Moliate: the art of bodily transfiguration (similar to Soulforging), a skill of the Masquers' Guild. •
Lifeweb: the art of manipulating Fetters and their connections to the Wraiths who possess them, a skill of the Monitors' Guild. •
Fatalism: the art of reading a Wraith's past, present, and future, a skill of the Oracles' Guild. •
Castigate: the art of taming the Shadows of other Wraiths, a skill of the Pardoners' Guild. •
Embody: the art of manifesting in the mortal world, a skill of the Proctors' Guild. •
Puppetry: the art of possessing mortals, a skill of the Puppeteers' Guild. •
Phantasm: the art of interacting with the dreams of mortals, a skill of the Sandmen's Guild. •
Outrage: the art of using telekinetic force, usually manifesting as traditional "poltergeist" activity, a skill of the Spooks' Guild. •
Usury: the art of manipulating and drawing on the emotional power of Pathos, a skill of the Usurers' Guild. Other Arcanoi exist in the possession of minor Guilds and other Dark Kingdoms. Spectres also possess their own Dark Arcanoi in addition to the standard wraithly Arcanoi. ==Release==
