For newer users you must know that using negative, black magick can come with side effects. These side effects can range from a minor headache to becoming extremely ill. Balance is key when being a magick user and if you are going to cast you must know that the only way to balance out negative is with positive. Grounding and warding spells are a must with using black magick. Also you are not the only one who can use black magick, people can reverse these spells on you. Please, be careful with what you cast and who you cast on.
Gods bless thee.
