A powerful way to hex or curse an enemy is with a voodoo hex bullet. Ideally, you locate an old battle ground, dig around to find a bullet, then at the witching hour, call down the spirits of warfare.
After that, you enter a possession trance and receive psychic battle sigils via “unknown tongues” (language of the voodoo spirits).
The voodoo spirits will then enter the bullet as you paint the sigils, and you will be ready for psychic battle.
My old voodoo mentor Earl Marlowe used to say:
“You gotta quarrel going down, an enemy on your back, take ’em down with a voodoo hex bullet. They’ll be lyin’ dead on the floor ‘fore 24-hours is up.”
