Vicissitude

Vicissitude is the art of shaping living flesh. It uses an esoteric skill, Body Crafts, which is a specialization of the Medicine skill. The first three levels all have two rolls: Intelligence + Medicine to activate the power, and Dexterity + Expression in order to do anything artistic. (This second roll is occasionally optional: for instance, making someone ugly is easy if you don't care about the Masquerade.) One blood point is spent per body part to be altered at both the first and second levels. (Grapple rolls are not necessary if the subject is willing or incapacitated.)

At the third level, weapons built from bone deal aggravated damage (+0).

Level four, Horrid Form, is the same as the book except that natural weapons now deal +1 aggravated damage.

One blood point must be spent to activate Blood Form, after which the vampire may convert as many body parts into blood as they choose. If enough of this blood is spent or destroyed that the vampire cannot reconstitute fully, they may choose which body parts to re-form. (For example, a vampire with only three blood points left could become a head and a torso, a head and two arms, and so forth.)
