Perhaps through biological expertise, or perhaps by unlocking something primordial within, you have accessed the secrets of bioluminescence. Using the Vicissitude, you may grant yourself (through Malleable Visage) or others (via Fleshcraft — both as per V20, p. 241) the ability to emit a soft glow. With muscle control and practice, you can control the color and pattern of the illumination. This can light a soft glow in the dark, create beautiful displays, or even act as a primal form of communication. Some Fiends grant their ghouls or childer bioluminescence, developing an eerily nuanced and wordless language with their thralls and broods. Only characters with at least one dot of Vicissitude may purchase this Merit.
