A powerful curse to inflict someone's sins and wrongdoings against them. Perfect for cursing an abuser and revealing their true nature while bringing them ruin. Best performed before midnight or sunrise to send out the energy with a new day.
A chime candle in white to represent how the person presents themself.
An ink made of dragon's blood resin and wormwood (grind them finely and steep in 90% or higher alcohol for several hours, if not several days, it will be sticky to the touch because of the resin)
Several nails, however many you seem fit. The rustier the better, I generally use 6.
A dish or something to hold the sand in
A baneful sigil or a taglock
Optional: A demonic sigil
Draw out the sigil on paper if you don't have a taglock and use that paper or the taglock to rub along the entire surface of the candle.
Dip the bottom 2/3 of the candle in the ink you've made and set aside to dry. While this happens, set up the dish with sand.
Take the nails and focus on your seething rage towards this person, how they made you feel, and what they've done. Push the nails into the ink-stained part of the candle (you may have to heat them a bit).
Take the sigil or taglock and burn it, setting the burning piece onto the black sand. When it burns out, place the candle into the sand and light it.
As the candle burns, speak out everything you wish to happen to this person. Wish their life ruined. Wish everyone to know what they did to you. Wish their life to be utter hell and chaos. As the nails drop, imagine them as gaping wounds in their facade that reveal their horrid soul for all the world to see. Spend the entire time the candle burns pushing your anger and energy into it.
As the last of the nails drop and the candle fades, picture their life crumbling down. Enjoy the sunrise of a new day knowing that they will no longer be a burden to you.
Optional: If you work with demons at all, set the demonic sigil on top of the remains and let said demon carry out the spell. (As a demonolater, I recommend Andras.)
After the curse is complete, destroy it. There is no need to treat this person kindly, so toss it out unceremoniously. Stomp on it. Spit on it. Do whatever you like.
