" After writing an Our Father backward on a page in blood, "you should carve runes on a staff and go to the cemetery at midnight with these two things, and go to whatever tomb strikes your fancy. However, it would be more prudent to attack the smaller graves.
You should then place the staff on top of the grave and roll it back and forth while reciting the Our Father backward at the same time,
following how it is written on the page, as well as some magic spells that few people know, except for witches. During this time, the revenant will slowly rise from the tomb, because this is not something that takes place quickly, and revenants will be praying greatly and saying: "Let me (rest) in peace.
