First of all, you are invoking black magic with your profile picture of an upside down pentagram. Writing spells can be challenging, but not always, remember to not make it ridiculous, or it won't work. Try to write it in a spellbook, a leather bound book with blank sheets, then try casting it, also say this incantation in your mind

Say it in your mind until you start casting it. Then try having someone else try it.
