Grimorium Verum, Plangiere translation:
Take the brain of a cock, the powder from the grave of a dead man (which touches the coffin), walnut oil and virgin wax. Make all [this] into a mixture, wrapped in virgin parchment, on which is written the words:
GOMERT KAILOETH, with the character of Khil.
Burn it all, and you will see prodigious things. But this experiment should be done only by those who fear nothing.
This spell invokes the demon Khil
