Your character has the ability to draw forth the sins of other individuals, restoring lost dots of Morality (or the equivalent trait for supernatural characters). The customary technique for doing this is to place a small piece of bread on the chest of the person whose sin you wish to eat, offering a momentary prayer, and then eating the bread, which has absorbed the subject’s guilt. Others rituals, subject to Storyteller approval, may work equally well.

To consume an individual’s sin, spend a Willpower point and make an instant contested roll pitting the Sin-Eater’s Resolve + Occult against the subject’s Resolve + Composure. The Willpower point only makes the roll possible, it doesn’t grant any bonuses to the dice pool. Each attempt requires a complete performance of the sin-eating ritual, which never takes less than thirty minutes.

Success allows the subject to attempt a new degeneration roll for a past sin. The subject makes this new degeneration roll as if his Morality was one higher; if this roll succeeds, the subject gains a point of Morality. Morality may never be raised higher than 6 through sin-eating and derangements are not automatically cured through sin-eating, but with the associated Morality dot returned, recovery becomes possible. At the Storyteller’s discretion, the subject may transcend his derangement if he goes a number of days equal to 10 – his Morality without sinning against his own Morality. Never erase a derangement overcome through sin-eating (see p. 93 of the World of Darkness Rulebook) — only real changes in behavior warrant that.

If the Sin-Eater achieves an exceptional success, both he and the subject enjoy a +2 bonus to their degeneration rolls for the ceremony.

If the Sin-Eater consumes a sin whose motive was driven by his own Vice, he regains a lost Willpower point exactly as if he had indulged the Vice himself. Likewise, if the sin was committed in the name of his Virtue (such as a vigilante killing for Justice or stealing from the wealthy to help the poor for Charity), he regains all of his spent Willpower as though he had acted on that Virtue.

Drawback: When you consume an individual’s sin, you are immediately subject to a degeneration check exactly as though you had committed the sin yourself. If you fail this degeneration check, you must check for a derangement as usual.

Example: Brother Roland, who is not actually a man of the cloth, is a practicing sin-eater at the local retirement home. He’s performing a ritual to consume the sin of a war vet with Morality 3. Roland spends a Willpower point and rolls Resolve + Occult versus the vet’s Resolve + Composure. Roland succeeds, and consumes the vet’s sin. The vet makes a new degeneration roll based on Morality 4 — the moral height from which he last fell — and so rolls three dice. He succeeds.
Roland, meanwhile, must deal with the sin he ate; because it falls beneath Roland’s own Morality of 5, he makes his own degeneration roll based on the same sin and fails. Therefore, Roland’s Morality drops and he must make a derangement check. Over time, Roland’s time with other people’s evils slowly erodes his own mind.
