Mirror Banishing Spell

Mirror Banishing Spell:
You will need the following items for this spell:
A small mirror
Photo or drawing of the person
Piece of onyx
A little bit of mugwort
Place the mirror flat on a table, and sprinkle a pinch of mugwort in one spot on the face of the mirror. Lay the photo face-down on the mirror so the face of the person is over the mugwort. Repeat the following words:
You cannot see me
You cannot hear me
You do not want me
Now let me be
Now set the piece of onyx on top of the photo, also over where the persons face is (or as close as you can get since the photograph is lying upside down at this point).
Repeat the words again, and leave the items on your altar to keep this person away. For the most powerful effect, cast this banishing spell on the night of the new moon.
