Infect your victims with your own supernatural essence: if this taint is left unchecked they become supernatural creatures as well.

Any victim who fails a Death Test caused by your unarmed or Creature Powers attacks must make a Magic roll with a difficulty of 10. You can spend Magic points to improve a victim's chances, one for one. If he succeeds, he does not die normally. Instead, he turns into a monster after the passing of three midnights. This may involve physical death, or it may not.

For additional schticks, you may reduce the amount of damage it takes to cause the metamorphosis. An extra schtick endangers anyone you damage. 

The victim's game statistics generally does not change, he retains all of his previous skills. He gains half of your Creature power schticks (selected by the GM) and the skill Creature Powers skill at the default value. At first he retains his original will and consciousness. But whenever confronted by an opportunity to act in a savage or monstrous manner, he must make a Willpower check with a difficulty equal to your Magic. If he is a player, the GM temporarily takes control of the character whenever he fails a cheek forcing him to act contrary to his player's desires. Once he has failed three of these checks his old personality is forever lost and a new bestial personality takes over. If a PC he becomes a GM character. This happens even if the creature that infected him appears to be a good entity: by definition, any creature willing to use Corruption is tainted by the foul spiritual essence of the Underworld.

Corruption remains reversible until the third Willpower check is failed. Extensive blood transfusion or the Poison Antidotes effect of the Sorcery schtick Heal are typical ways to reverse the effect.

For each living and active character you have corrupted and still control you gain 1 Corruption Point. A Corruption Point can be spent at any time during a session for a +1 bonus to any Action Value for one action only. Multiple Corruption Points can be spent on the same action. Your pool of Corruption Points returns to maximum value at the beginning of each session. It can never be higher than your Magic attribute.

If you spend an additional schtick on Corruption you gain the ability Domination with no Magic point cost and at a +6 bonus to your Creature Power Action Value: this specialized form of Domination can be used only on characters who have become supernatural creatures due to your Corruption ability.
