How To Perform The Killing Curse

First set up your brewing station, you'll need a bunsington burner and a stand for you cauldron. Then, using your magic wand, light a dark flame.

Then you'll need to add some water to your cauldron, I'm using double-cursed lake water.

Then you'll need some dried petals from the deadly nightshade plant.

Crush the petals into a fine powder using a pestle and mortar.

Then pour the grinds into your mixture.

Next, you'll need one lanson's jar of crimson tendrills. Pour the tendrills straight into the cauldron from above.

Then you'll need the juice of 100 devil eye butterflies, this can be hard to find as the butterflies only live on the remote island of Manchester.

Stir your mixture well and using a spoon serve up some of the potion into a chalice.

To activate you'll potion you'll need to add one drop of blood to the chalice.

Drink the potion and instantly you'll have the power of the killing curse.
