(2 point Flaw)
You are excited either by causing pain or receiving it. In many situations, you will seek either to be hurt or hurt someone for your pleasure. For a masochist (someone who enjoys pain), your soak roll for actual physical damage is increased by one because you really want to feel the pain. A sadist (someone who likes to hurt others) must make a Willpower roll (difficulty 5) to stop combat (modified depending on how much you are into the attack and how much you are enjoying hurting the other person). If you fail, you are so caught up in the event that you are unaware of anything else happening around you.
