I bought three St. Michael candles (I intend to eventually use nine, but will buy them in batches). I burned some bay leaves for incense and dressed them with Fiery Wall of Protection Oil. Then I wrote the name of the person threatening them on brown paper and crossed it out, then put it face down under the candle. I also dressed a small sword (you can use a knife, I happened to have a letter opener in the shape of a sword) with cinnamon and clove oil and place it in front of the candle.
As each candle burns down, I will light the next one. I intend to keep this up through nine candles.
