Rank 2

Bitter Blood = Quietus 2 + Vicissitude 2  –  The player spends a blood point and makes their blood taste absolutely foul for the scene.  Someone attempting to drink their blood must succeed as a Stamina roll diff 7 each round they continue to make the attempt.  Failure means they vomit and must spend Willpower to even bring themselves to try again for the remainder of the scene.  There is an advanced rank of this, using Vicissitude 5 instead, which causes actual damage in addition to these effects.
