Oh, you should never mess with dark entities. That's a major no-no. Allowing them into your life, or worse, your home can lead to them torturing you and draining you of your life essence. Sometimes you don't even need to invite them. They attach themselves to you, follow you to your home and make your life absolutely miserable. And Goddess knows I have enough problems with being miserable already.

Then you'd have to go through blessing the property and that in and of itself is very draining. The more powerful the caster of the blessing the more effective it is, and the more powerful dark entities need powerful blessings to vanquish them.

No dark magic for me. No way. Goddess forbid I hurt myself, or another with my disregard for the powers that be. I only dabble in white magic, if any, and only that which I am comfortable with.
