Tenebrous Avatar
The Cainite using this power can transform her body into an inhuman shadow. The form this living shadow takes depends more on the character's inner nature than on her mastery of Obtenebration. For some, the form may be undulating and serpentine, while it might be a formless cloud for others. Still others might take an ominous and imposing monolithic shape. While assuming the Tenebrous Avatar form, the Lasombra is virtually immune to harm, and she can pass through slight cracks and very small openings by extruding her shadow essence the necessary thickness.
The touch of the Tenebrous Avatar is disconcerting to mortals, and taking on the shape brings the sensation of being in the grasp of a cold and inhuman otherworldly being. Lasombra lore talks of this power as a step towards becoming Ahriman itself, a mixed blessing indeed. The character can also see through even the deepest blackness while in Tenebrous Avatar form.
System: The player spends three blood points while the character takes three turns to transform. This transformation time can be reduced by one turn for each additional blood spent, but it always takes at least one full turn. while she is a Tenebrous Avatar, the character is immune to physical damage, but she cannot physically attack others. The most she can get away with is to wrap a victim in inky blackness, which is frightening enough to most beings to require a Courage roll to avoid panic. The character can, however, summon Arms of Ahriman from her form and the surrounding shadows, but she must do so separately.
Your character is still vulnerable to fire and sunlight in this form, and she is even more vulnerable to them psychologically, as the darkness of which she is now made recoils insanely from its opposite force. Add one to the difficulty of Rotschreck rolls when exposed to fire or sunlight in Tenebrous Avatar form.
