What u need: nothing
Spell:It is very important to be able to see strands or bonds or knots that hold it together.Those are what you are going to release slowly.Do note that this spell can take a long time depending on the strength and complexity of the evil. You must imagine yourself undoing the knots or bonds and then say out loud as many times as needed:
I bind this evil from doing harm To those around us And itself I bind it to be free But not harmful.
