Misfortune Hex

You may want to do a protection spell before you cast this. NOTE: The protection spell will not stop the threefold law but it will lessen its effects.
Use the salt to make a circle large enough for you to sit in the middle. Then, place the candles at the five points of the pentacle (right side up) going anti-clockwise, starting with 'Spirit'. Say the names of their point of position as you light them. You may wish to do this after, or while you are placing them, whatever you feel comfortable with.
Sit in the middle of your circle with your legs crossed and your palms facing upwards, towards the sky. Close your eyes and breathe deeply or meditate and imagine yourself merging with the pentagram you have now created with the salt and the candles. Now say:

 

"This person has done me wrong,
Mighty Hecate, I call thee.
Come to my aid, and punish those that have hurt me.
Make them feel remorse, and regret their existence.
I give to you the moon, in return for my asking."

Whilst you are saying this, think of the person of which you wish to place this hex on. You can use a photo or picture of them to help you but this is not compulsory for the spell to work.
Now return to your breathing/meditating and repeat until you feel it is done:

"Misfortune, misfortune,
Turn their way."

You must also imagine the person in question with this too. Once relaxed, stand up, extinguish the candles and say:

"So mote it be."

NOTE: You must not attempt this spell in a state of happiness or positive feeling towards the person you wish to hex, otherwise they shall not be cursed but you may. No amount of protection spells or power of them for that matter will prevent the threefold law from reaching you, the most it will do is buy you time, or lessen the effects. This is also a weak hex/curse and the effects may not last long or occur immediately. If you want something more powerful look elsewhere. If you wish to leave the circle there as a sign of protection you may but remove it the next night otherwise it will bring you bad luck.
