I'm going to put a few different levels of revenge.

Simple Annoying Curses:

"To performs these, light a black candle, burn a piece of paper with the name of the person you want to curse, and whisper what you want to happen before blowing out the candle.

-May you step in water while wearing socks

-May you never find the cold side of your pillow

-May Netflix always buffer

-May your teachers always round your grades down

-May you forget your homework

-May your pencil lead always break

-May you never remember your passwords

-May you forget a family member's birthday."

More intense revenge spells:

For bad luck:

You will need:

-A candle

-a bowl of cold water

-a strip of paper

-quill with ink(a pen will be fine)

First you light the candle near the bowl of water. Write the full name of the person whom you wish to cast the spell on, on the strip of paper. Speak the spell into the flame, making it flicker. The spell for misfortune:

"Alaka Mon At-tu Al(Al-aka, mon, at-too, ay-la) May luck fade, dying away Kissa ra oreume(key-sa, ra, or-em) Luck burns away from thee, until thy water sets thy free Quet Revera Sef Mopilee Aquar Pudeo (key-et re-vehr-a seph mop-e-lee aquar pood-eo)"

Now place the paper into the fire. As soon as it disappears and turns into ash, say the following,

"Seven days of misfortune torture thee, but after the spell will be released Meria Colenso peressi alakanomen nerye duli (mur-ea Colenso par-e-see ala-ka-nom-en near-ye duel-e)"

Dip the candle into water until the flame sizzles out. As soon as this happens the spell will instantly show effects and will last for seven days. I guarantee it will work if used properly although sometimes the misfortune may not appear so obvious.
