Iv'e read his seven faces of darkness before, like I said on my previous post "I find his frame rite useful," but I do not necessarily find his spells to add being useful." I do however improvise a lot during ritual such as visualizing the Pentagram of Set seeing it transform to earth and by visualizing my enemies and the change its causing.
I've never liked spells, in fact a half spell book is usually a turn off for me. I did write one based on the pyramid texts though:
Greetings to Khepri who created himself, who comes into being in thy name of Khepri. I have come into being. Nephthys praises me: “you have equipped yourself as the Great-in-magic, Set. Nothing is lacking in thee, nothing ceases with thee. You are more glorious and powerful than the gods of Egypt and their spirits. You are equipped as Set, who mightily broke forth. Set, who is more powerful than his father. If you go Horus goes, if you speak Set speaks.”
Horus has caused me to recognize Set in myself without him getting away, to seize the hand of Set without him escaping. My arms are like those of Set when he ascends and lifts himself to the sky. I have escaped the day of my death as Set escaped the day of his death. I am as Set, who once suffered want and decided to live on the being of every god, who ate their entrails when they were full of magic. I send Khonsu to slaughter the gods and bring me their entrails, Khonsu is the messenger I send forth to punish. I have thrown Osiris to the ground, I have left Horus behind me. Nuit opens the heavens to me and places me among the imperishable stars. I look down upon Osiris, I stand far from him. I am not of them, I shall not be of them. Let not Osiris come in his evil coming, do not open your arms for him, let him be gone.
I ascend to the heavens and the heavens rejoice for me. The earth quakes for me, the storm roars for me. I howl like Set and the doors of heaven open for me between the two thighs of Nuit. Set and Nephthys announce me to the gods: “he has come as an imperishable spirit, if he wishes your death you shall die.”
