A foe-killing ritual
This very effective ritual uses Reranber, who is one of the forms of Nyarlathotep. John Dee writes of him in Grimoirium Imperium: "The name of the fifteenth hour is Reranber, who is the most malevolent spirit and will murder anyone at your command. Reranber appears as a prince in glittering gold holding a black sword."
Then, say the following incantation: "I am He, the great and mighty God, the one who knows. I am Nyarla-Thot-Ep, who has given a name to everything, and therefore you are...(name of the victim)...and let there be no difference between wax and flesh! Y-hah, Iä Nyarlathotep!"
Prepare a dagger, and on a paper of such size that the figure may lie on it we will draw the black sigil of Reranber.
We proceed to the ritual itself at the beginning of the 15th hour with the incantation: 'I...(insert your name)...invoke you O Nyarlathotep, that I may offer you the soul and body of (name of your victim), invoke your form Reranber, for the terrible task! I call you O Reranber from the farthest depths of the cosmos, I curse you with a terrible formula that cannot be translated: 'Zazas Zazas Nasatanada Zazas, come and accomplish my task! I command you by the will of Azathoth, which no one can oppose, kill and destroy (name of victim)!"
Raise the knife and say, `My body is now the body of Reranber! I am Reranber, the terrible murderer of ancient Kem, and I do the will of Azathoth the creator-god himself, which nothing can prevent or oppose! Death to (name of victim)!" Then coldly plunge the knife into the wax figure. Continue stabbing, imagine blood oozing from each wound, viscera crawling out of the lacerated abdomen, your enemy on the table before you gasping for breath, gagging for blood, his life ebbing from his body and turning into a corpse. Then put down the knife and say, "The will of Azathoth has been done!"
You may bury the figure of the murdered corpse and burn it after the enemy's death.
