Shadow of Apep
Only Set and Set's own childer can perform this terrifying power. These ancient monsters cna take the form of Set's defeated enemy, Apep. The vampire becomes a giant serpent of fluid, glittering Darkness - not mere shadow, but anti-light, like the black force commanded by Obtenebration. Int his form, physical force cannot harm the vampire: not claws or fangs, not bullets, not explosions, not anything except fire, sunlight or magic. Physical barriers cannot easily stop the vampire, whose shadowy form can seep through even the tiniest crack. The vampire, however, can still exert physical and supernatural force quite freely.
System: Taking the form of Apep costs a Willpower point; the vampire stays in this form for a scene. The transformation takes three turns to complete. IN this form, the vampire takes no damage from any physical attack: fists, weapons or falling buildings pass through the vampire as if she were a shadow. Fire and sunlight inflict the normal aggravated damage, however, and magic still affects the transformed vampire. The vampire itself gains three dots in each Physical Attribute. The transformed vampire can use its Strength to make normal close combat attacks and can bite for Strength +2 dice of damage. The vampire can also employ any Discipline that does not require hands.
