Graft Life to Life
With normal Vicissitude, a Tzimisce may take the arm from one person and graft it to another, but the recipient is unable to control the arm and it soon begins to decay. With this power, the user may take body parts from living creatures and graft them on to others, living or undead, and allow for the recipient to use the new limb. Exceptionally monstrous and disturbing creatures can be created with this power or one may graft extra organs into others, allowing them to function longer while wounded.
System: Removing a limb requires an Intelligence + Body Crafts roll (difficulty 6). Extracting an organ is an extended Intelligence + Body Crafts roll (difficulty 7), with 10 successes required and each roll representing an hour of work. The process of grafting must then begin within an hour. or the limb or organ dies. Attachment is an extended roll of Intelligence + Body Crafts (difficulty 7), requiring 10 successes and each roll representing half an hour's work. Attaching an appropriate limb, such as a human arm to a human, is difficulty 7. Attaching an inappropriate limb, such as horse legs to a human, is difficulty 8. Inserting organs is difficulty 9. Attaching limbs to a vampire is somewhat easier (difficulty 6). Theoretically, one could put organs inside a vampire, but this has no effect.
The effect of attaching extra limbs is entirely up to the Storyteller. Extra arms might help in grappling and multiple attacks and extra legs might aid stability but the main effect is generally freakishness rather than effectiveness, since coordinating the extra limbs is very difficult. Extra organs grant the recipient an additional wounded health level per organ, though a maximum of two can be grafted.
