Devil Lord Transform

This spell must be cast a midnight. You crush the gems up into a fine powder. You make a circle 10 feet diameter with smaller circles of a one foot diameter circling the inside of the big circle. Then place the parts of the demon lords in the inside circles. You then repeat the names of all of the demon lords in order of how you placed them, facing the pert of the demon lord you say. You then open a portal to the forbidden 10th level of hell. You don't fall through. The evil magic from the 10th level of hell then surrounds you. You then turn into the first demon lord you said. Then the next day you turn into the second one you said, and so on for 9 days. An hour after the spell ends, a portal to the 10th level of hell open beneath you and drags you down into it's depths. Only a 20th level wizard that casts the wish spell every day for a year can bring you back. And on the last day the wizard dies. If you come back, your alignment changes to neutral evil, and the evil of the place you were in changed you. You have insane and only a wish spell can undo the insanity. You will never take company for granted again, for you only will meet one other creature while you were there, if you are lucky. And you can never fall in love again, of be charmed. Once a person has cast the spell, and come back, they can never cast the spell again, because of the fear of being back in the 10th level of hell.
