Black magic is not something you should play at all. Its very dangerous but if you're new and want to try dark arts. Feel free to ask questions on here or need help if needed. I know there are pretty wise people here that know a lot. :)
For those that are new and looking for beginner spells. To be honest, creating your own spells a lot easier. All you need to know is what type of spell you plan to do: love, hate, hurt, etc. What things you need to make the spell work like candles, crystals, and herbal. Put emotion into the spell poke for example: say I want to do a love spell and I need to feel being in love.
Also know what to name your spell and know what it does and how to do it.
so all you need to do is :
Name of the spell
What does it do?
What are the ingredients for the spell?
How do you do it?
The spells you create would better to put in a journal.
So that all I have to say. Again feel free to ask questions or give any advise.
