-The Arm of Saint Lawrence-
While not actually the arm of the third century saint, this artifact was once used by a cult devoted to him. The church purged the heretical cult long ago, but this artifact escaped destruction. The arm is covered in the dark red splotches of a burn victim. The skin is well preserved, and held rigid by its original bones. It is filled with a viscous, smelly fluid which makes it appear bloated. The arm is mounted on the end of a four foot iron staff. It is extremely heavy, and if used as a weapon suffers a -2 to hit.
The wielder of the arm can touch people with the hand, and invoke a blessing to the saint. Those who experience this feel a vague, but pleasant, sense of serenity and connection to the divine. With this power, it would not take much effort to begin the cult anew, though the church would frown on such activity.
The staff’s wielder is immune to feelings of pain. They are aware of pain, and can interpret its severity, but they are not inhabilitated by it. They can act normally while their hit points are between 0 and -3. (Though, like any character, once they have reached -3 they will die in 1d10 minutes).
If the staff’s wielder falls below 1 hit point, any damage they take after that is divided evenly between themselves, and everyone they have blessed within the last 24 hours. The effect can occur even mid-damage roll. So, if the staff wielder has 2 hit points, and takes 4 damage, they take the first two damage normally, and are reduced to 0. The remaining two hit points are divided between them and the blessed.
If the damage does not divide evenly between the character and the blessed, determine randomly who takes damage. But keep track. No character should take a 2nd point of damage until every other has taken a 1st point.
When the staff’s wielder dies, they and each character they have blessed become powerful revenants with burning hands, which subsist on human ashes.
