This will add the guarantee to any of my spells. It will not be cheap but if you purchase any of my spells, this will add the guarantee that it will work. IE: I won't stop, no matter how long it takes, to ensure it works for you. Normally you cast spells, and they work but for some, if you are clogged more, or in need of more specialized work this will guarantee it works. now my spells do work, but like I said, sometimes you need a more personal and specialized touch, this is going to give it to you. I hope that makes sense, if you have purchased past spells, this will work on those as well. but you must remind me which spells it was so i can personalize it and work with you for a more successful outcome.
