Just a newb question. I've a friend (group of friends, actually) coming under prolonged attack from an individual magician. She has boasted of using all paradigms, including the Necronomicon. My friend is considering using the Nec seals of certain spirits for household protection.

My question is: I think there are some preperatory rites or actions that need be taken prior to doing this. Is that correct. And do they make good protection for a household or an individual? Any advice or help would be appreciated, since I do not want to see her run into problems.

Thanks.
