A ghostly Presence has a powerful tie to the formless Aether, decreasing or negating effects targeting them. The material world can barely affect a presence of this type. Entities with a Presence of this type are susceptible to effects which leave a Spiritus type manifestation upon their true death. The farther away their Presence is from the Material or Numinous, the less likely it is for such effects to accomplish this. These entities often require, or at least desire, Eternal Repose.
Spark: All but Tainted; the all-spark which it may use to pass on its own powers to others.

They gain immunity to non magical physical attacks (bludgeon/pierce/slash) and damage. They have resistance to all magical forms of damage (acid, cold, fire, lightning, thunder, etc.). They cannot be paralyzed, petrified, diseased, or poisoned. Physical grappling, restraint, unconsciousness, or knocking prone all have no impact on the presence. Sources of damage which themselves are Ghostly cause harm normally. Phantasmal sources of damage reduce immunity to resistance, and resistance to normal effects.
