I know that someone already answered this, but some are fake and some are not. But the best to save your energy is to not waste them on fantasy spells, think about mermaid spells. Do you really honestly think you can change who you were born into some other creature? But some realistic spells on here have purposes, I was going to suggest the Lark topic as well. If you're just starting out, read some articles and books about it. You should get pretty good info, it's really helping me and it's helping me give better advice as well. But if you need help on anything you can contact a knowledgeable person to help you that you feel comfortable with.
I really hoped this helped you!
