Haha, that's funny, curses easy?
Lol, curses are the hardest type of spells to cast, or master.
White, try some protection spells, hun, they are the easiest in my opinion. Plus, they are very helpful here's a long list of them: http://www.everythingunderthemoon.net/spells/protection-banishing-curses.htm
Also, you might want to start writing a few, the spells you write are usually the most powerful, they also seem to backfire less. Before you start casting any though make sure you cast a magick circle you can get the instructions for that here: http://www.meddevi.com/witchery/circle.html
I wish you luck on your magickal journey :)
I would agree with Kyori try protection spells there are many out there and some are really simple or so u can get better at spells pratice doing psionics cause though it may seem hard at first its a great way to learn how to direct energy for when you do harder spells.
Yeah everyone should know the dangers of black magic but she can learn that as well as the directing of energy to a spell cause if she doesn't know how to direct her energy its just going to go everywhere possibly coming back on her in a bad way.
