Vicissitude is the signature power of the Tzimisce and is almost unknown outside the clan. Similar in some respects to Protean, Vicissitude allows the Fiends to shape and sculpt their own or others' flesh and bone. When a Tzimisce uses Vicissitude to alter mortals, ghouls and vampires of higher generation, the effects of the power are permanent; vampires of equal or lower generation may heal the effects of Vicissitude as though they were aggravated wounds. Naturally, a wielder can always reshape her own flesh.
Note that while this Discipline permits powerful and horrific effects, the wielder must obtain skin-to-skin contact and must often physically sculpt the desired result. This even applies to the use of the power on oneself. Tzimisce skilled in Vicissitude are often inhumanly beautiful; those less skilled are simply inhuman.
Note: Nosferatu always "heal" back Vicissitude alterations, at least the ones that make them better-looking. The ancient curse of the clan may not be circumvented through Vicissitude, except possibly by the Antediluvian of the Tzimisce clan (who is rumored to have been destroyed anyway).
A vampire with this power may alter her own bodily parameters: height, build, voice, facial features and skin tone, among other things. Such changes are cosmetic and minor in scope - no more than a foot of height gained or lost, for example. She must physically mold the alteration, literally shaping her flesh into the desired result.
This power is similar to Malleable Visage, above, but allows the vampire to perform drastic, grotesque alterations on other creatures. Tzimisce often use this power to transform their servitors into monstrous guards, the better to frighten foes. Only flesh (skin, muscle, fat and cartilage, but not bone) may be transformed.
A vampire may use this power to move clumps of skin, fat and muscle tissue, thus providing additional padding where needed.
This terrible power allows a vampire to manipulate bone in the same manner that flesh is shaped. In conjunction with Fleshcraft, above, this power enables a Vicissitude practitioner to deform a victim (or herself) beyond recognition. This power should be used in conjunction with the flesh-shaping arts, unless the vampire wants to inflict injury on the victim (see below).
Vicissitude is as much an art as it is a power, and vampires who wish to use it well must learn a particular version of the Crafts Skill, known as Body Crafts. This Skill enables its possessor to make all manner of alterations to living and dead flesh and bone. The Skill also gives insight into more mundane techniques; many Tzimisce are skilled at flaying, bone-carving, embalming, taxidermy, tattooing and piercing.
The vampire may utilize this power (on herself or others) to form spikes or talons of bone, either on the knuckles as an offensive weapon or all over the body as defensive "quills." If bone spikes are used, the vampire or victim takes one health level of lethal damage (the vampire's comes from having the very sharp bone pierce through his skin - this weaponry doesn't come cheaply). These health levels may be healed normally.
