Apep's Semblance
The Followers of Set developed this power to defend against the affronts of mortals and undead alike. The Setites claim that this power channels Set's own spirit, transforming them into a blend of human and snake. When a Cainite activates this power, his legs fuse together and grow into a tail that stretches over 10 feet in length. His torso and arms lose their rigidity, becoming much more limber. His fingers sprout webs. The vampire's neck thickens and stretches, gaining flexibility like his tail. His face extends out into a serpentine muzzle. His teeth grow grotesquely long. A mottled hide covers his body.
System: The player spends three Blood Points and the vampire assumes this shape, which takes three turns to develop (spending additional Blood Points reduces the time of transformation by one turn per point spent). A vampire wearing Apep's Semblance is gifted with more than a disturbing shape. The large, sinuous form can squeeze through openings less than a foot in diameter, and it can swim twice as fast as the most accomplished human swimmer. The difficulties of Perception rolls based on smell are reduced by two due to the Cainite's acutely sensitive tongue; this tongue may be used like Tongue of the Asp. Furthermore, Strength and Stamina increase by two, and Dexterity by three, but Appearance drops to 0 (the vampire's Charisma and Manipulation remain the same due to the snake's hypnotic movement). The tail can strike for Strength + 1 bludgeoning damage, and may grapple an opponent (treat as a grappling combat maneuver), while the Setite's bite inflicts Strength + 2 aggravated damage, and does not require a successful grapple to hit. Finally, the vampire's tough skin adds one die to soak rolls. The Setite retains this form until the next sunrise, or until he wishes to change back.
It is possible to invoke Skin of the Adder while in this form, and receive all relevant benefits.
