Skin of the Adder
Every new power of the Discipline of Serpentis brings the vampire closer to the god-form of Set himself. The Skin of the Adder brings this blessing to the vampire's undead skin, using vitae to strengthen and thicken it. His form also becomes more snakelike, though it is still obviously humanoid.
System: No roll is required, but the change takes three turns and costs one blood point. If the player spends three blood points at once, he can reduce this time to one turn. While wearing the Skin of the Adder, the character is scaly, mottled and clearly monstrous. This power reduces soak difficulties for all damage to 5. In addition, the player can use Stamina to soak aggravated damage from claws and fangs (though not from fire or sunlight) even if the character does not have Fortitude. Additionally, the vampire is more limber and his joints become capable of dislocating without damage. He can fit through any opening large enough to admit his head, and he can dislocate his jaw to allow one more blood point to be consumed per turn of feeding.
