Seed of Corruption
This power originated with the Typhonic Setites of Constantinople - probably with Khay'tall himself. The more devout (or fanatical) Setites do not know about it and would consider it heretical if they did. Seed of Corruption is a powerful tool when it comes to subjugating an enemy, slowly eroding away his morals and ethics.
System: Seed of corruption requires that the target consume at least one blood point from the Setite. Once this blood has entered the victim's system, the player must roll Manipulation + Subterfuge, with a difficulty equal to the target's Road rating (or Willpower, if the target has no Road rating). The power lasts for one lunar month per success.
The effects of Seed of Corruption are threefold. first, it delves into the subconscious of the victim and causes buried or repressed desires and hatreds to flare up suddenly from time to time. At least once per night (more frequently should the victim come face to face with an object of her desire or hatred), the victim should suddenly feel an impulse to act in a manner appropriate to her subconscious desire or hate. for example, she may find herself wanting to murder a rival's favorite ghoul, despite the possible repercussions. generally, it requires a Willpower roll (difficulty 6) not to give in to the compulsion (though great stress or other factors might modify this at the Storyteller's discretion).
Second, Seed of Corruption increases the intensity of feelings and thoughts that the victim is trying to repress. All Conscience/Conviction rolls are at +2 difficulty.
Finally, the victim's thoughts tend to gravitate toward her greatest insecurity or point of pride, depending on the type of person the victim is. A narcissistic Toreador might find that she contemplates her own beauty quite often, being distracted even during important matters by any reflective surface; while a devout Brujah who questions his own piousness might be wracked by pangs of remorse and guilt. whenever a situation that touches upon these insecurities or prides arises, the victim must roll Self-Control/Instinct (difficulty 7). If this roll is failed, the victim gives in to the urges. the narcissistic Toreador might spend hours pampering herself or seeking praise while the devout Brujah might seek out a confessor or flagellate himself for his doubt.
